Technical Profile

Aero Enterprises stocks secondary stainless steel sheets in SS 304, SS 316, and SS 202 grades at Unit II Dhumal Nagar, Vasai East, at 15–20% discount versus prime. Secondary SS sheets carry minor cosmetic imperfections — surface scratches, handling marks, edge damage, or 2B finish variations — from manufacturing, processing, or transit. These are surface-level issues only. The chromium content, nickel content, chromium oxide passive layer, corrosion resistance, tensile strength, and weldability of secondary SS are identical to prime material. Thicknesses from 0.8mm to 2.0mm are stocked in standard 8x4 ft (2440mm × 1220mm) subject to current mill overstock availability. Secondary SS sheet moves quickly — availability is unpredictable and batch-dependent. Contact the sales desk for current grades, thicknesses, condition photos, and today's per-sheet price before planning a project quantity around secondary material.

What Are Secondary SS Sheets – Definition and Properties

Secondary stainless steel sheets are prime-grade material that failed cosmetic grading during manufacturing, finishing, or handling — but retain full ASTM A240 chemical composition and corrosion resistance. The passive chromium oxide layer that prevents rust is not removed by surface scratches — it re-forms instantly on exposed metal. For the full definition of what stainless steel is, see our <a href='/products/ss-sheet-supplier-mumbai'>SS Sheet guide</a>. Common imperfections found in secondary SS sheets: surface scratches from light to moderate depth, handling marks and dents from transit impact, 2B surface finish irregularities or uneven reflectivity, slight discolouration from heat or chemical exposure, edge nicks or irregular sheared edges, minor pitting or mill blemishes from rolling or annealing, and strapping or stacking marks. None of these affect chemical composition, tensile strength, yield strength, ductility, or weldability.

Secondary SS Sheet — Available Grades

Certified Grade Variations in Stock

Inquire Grade Availability
1

SS 304 – Most Consistent Secondary Supply

The most reliably available secondary grade. Build procurement programs around SS 304 secondary — predictable batch availability versus other grades. Full 18% Cr / 8% Ni composition. See the <a href='/products/ss-sheet-supplier-mumbai#grades'>SS Sheet Grade Guide</a> for complete SS 304 technical specification.

2

SS 316L – Rare, Batch Only

SS 316L secondary is intermittent — SS 316L is produced in smaller quantities so secondary batches arise infrequently. Do not plan a continuous production program around secondary SS 316L. Confirm availability at time of enquiry.

3

SS 202 – Occasional Availability

Already 30–35% cheaper than SS 304 prime. Secondary SS 202 is the most cost-effective SS option for dry indoor non-contact applications. Availability is batch-dependent — confirm stock before planning.

4

SS 430 – Ferritic, Limited

Magnetic ferritic grade. Secondary availability is rare and highly unpredictable. Only plan SS 430 secondary use if you have confirmed batch stock on-hand.

Secondary SS Sheet Weight Reference

Secondary SS sheet weight formula (same as prime): Weight (kg) = Length (m) × Width (m) × Thickness (mm) × 8.0. For standard 8x4 ft (2440mm × 1220mm): 2.44 × 1.22 × Thickness (mm) × 8.0. Quick reference: 0.8mm = 19.0 kg, 1.0mm = 23.8 kg, 1.2mm = 28.6 kg, 1.5mm = 35.7 kg, 2.0mm = 47.6 kg per sheet. Actual secondary sheet weight may vary marginally due to dimensional tolerance of ±2–3mm. All secondary SS consignments from Aero Unit II are weighed on the certified 50-tonne digital weighbridge with full weight documentation.

HSN Code and GST – Secondary SS Sheet

Secondary SS sheet invoiced under HSN 7219 — same as prime. Classification is by product form and grade, not cosmetic condition. GST: 18%. GSTIN: 27AGCPK5633K1Z9. Full 8-digit HSN sub-code breakdown by thickness: see <a href='/products/ss-sheet-supplier-mumbai#hsn'>SS Sheet HSN Code guide</a>.

Technical Q&A

Verified Procurement Intelligence

Is secondary SS sheet still rust-proof?
Yes. Corrosion resistance in stainless steel is a function of chemical composition — specifically the 10.5%+ chromium content that forms a self-healing chromium oxide passive layer on the metal surface. Surface scratches do not remove this protection — the passive layer re-forms instantly on the exposed metal. Secondary SS 304 with scratches has identical corrosion resistance to prime SS 304 with a flawless surface. The scratch affects appearance only, not the underlying electrochemical protection mechanism.
How much can I save using secondary SS sheets?
15–20% below prime at current Mumbai rates. Example: SS 304 1.2mm prime = approx ₹5,580/sheet (28.6 kg × ₹195/kg). Secondary = approx ₹4,640–₹4,750/sheet — saving ₹830–₹940 per sheet. On a 50-sheet order: ₹41,500–₹47,000 saved. On a 5-tonne project, the saving on the secondary-grade portion can reach ₹1.5–₹2.4 lakh depending on grade and thickness mix.
What is secondary SS 304 sheet price per kg in Mumbai?
Secondary SS 304 sheet price per kg in Mumbai as of May 2026 is approximately ₹155–₹170/kg versus ₹190–₹210/kg for prime. Per sheet for 1.2mm (28.6 kg): approximately ₹4,430–₹4,860. Price varies by batch condition — lighter cosmetic defects attract 15% discount, heavier defects attract 20%. Call +91 8459121717 for current secondary SS 304 pricing and condition confirmation.
Can secondary SS be used for food equipment surfaces?
For non-contact surfaces — frames, stands, backs, legs, and structural panels — secondary SS is correct as supplied. For food-contact surfaces (product contact zones), the same material applies but requires polishing to remove scratches before use, as scratches can harbour bacteria that compromise hygiene. In food processing environments, product-contact surfaces must meet the applicable finish standard (typically Ra 0.8µm or smoother). Use prime SS for food-contact surfaces and secondary for all structural and non-contact components of the same equipment.
Can scratches on secondary SS be removed?
Yes, partially. Light to moderate scratches can be significantly reduced through progressive sanding — 180 grit → 320 grit → 600 grit abrasive followed by SS polishing compound. The result will match a No. 4 brushed finish rather than restore the original 2B smoothness. Deep gouges can be minimised but not fully eliminated without specialist grinding. For powder-coated applications, light 180-grit scuff sanding is all that is required — the coating fully covers all surface marks.
Is SS 316 available in secondary grade?
Occasionally, but secondary SS 316L is rare in the Mumbai market. SS 316L is produced in smaller quantities than SS 304, so secondary batches arise less frequently. Do not plan a continuous production program requiring regular secondary SS 316L supply — availability is batch-dependent and unpredictable. Contact the sales desk to check if secondary SS 316L is currently in stock. For reliable 316L procurement, specify prime material.
Can secondary SS be welded?
Yes. Secondary SS welds identically to prime material. Use ER308L filler for SS 304 and ER316L filler for SS 316. Clean surface marks near the weld zone before welding for best bead appearance. Corrosion resistance is maintained in the heat-affected zone with correct inter-pass temperature control (below 150°C for austenitic grades to prevent sensitisation). The cosmetic imperfections on secondary material do not affect weld quality or metallurgical performance.
How is secondary SS priced relative to defect severity?
At Aero Enterprises, secondary SS pricing reflects grade, thickness, and defect severity. Light cosmetic surface marks — minor scratches, light strapping marks — attract 15% discount vs prime. Moderate surface damage — deeper scratches, moderate dents, edge damage — attracts 17–18% discount. Heavy cosmetic defects attract 20% discount. Condition photos are provided via WhatsApp before purchase so you can assess suitability for your application before committing.
Do you deliver secondary SS sheets across Mumbai?
Yes. Delivery covers Vasai-Virar, Mumbai, Navi Mumbai, Thane, and Palghar from Unit II Dhumal Nagar. Minimum 3 sheets recommended for economic delivery given SS's higher per-sheet value. For 10+ sheets, transport is arranged with protective packaging to prevent additional surface damage in transit. Same-day dispatch for confirmed orders before 12 PM for local Mumbai region.
Can I reserve secondary SS stock before deciding?
For bulk orders of 10+ sheets, Aero Enterprises holds stock for up to 7 days with a 25% advance payment. Secondary SS sells quickly due to limited and unpredictable mill supply. Once suitable material is confirmed and condition photos shared, a fast decision is recommended — unconfirmed secondary stock is released back to open availability within 24–48 hours. Call +91 8459121717 to check current availability and initiate a hold.
Does Aero Enterprises fabricate from secondary SS?
Yes. Aero Enterprises Unit I Vasai Phata processes secondary SS sheets through the full fabrication sequence — 3000W fiber laser cutting, CNC press brake bending (100T, 3100mm), MIG and TIG welding, and 7-tank powder coat finishing. Finished components from secondary SS are functionally identical to prime-material components for all non-cosmetic and non-food-contact applications. Secondary SS + in-house fabrication is the most cost-efficient route for OEM equipment interiors, industrial enclosures, and structural frameworks.
What is the HSN code for secondary SS sheet?
Secondary SS sheet is invoiced under HSN Code 7219 — flat-rolled products of stainless steel, width 600mm or more. Classification is based on material form and grade, not cosmetic condition. 8-digit: 7219 3300 (1–3mm cold-rolled), 7219 3400 (0.5–1mm). GST rate: 18%. GSTIN: 27AGCPK5633K1Z9.
Which SS grades are available in secondary at Aero Enterprises?
SS 304 is the most consistently available secondary grade. SS 202 is occasionally available. SS 316L is rare but possible. SS 430 in limited batches. All grades are subject to current mill overstock — confirm availability at the time of your enquiry rather than assuming a specific grade is in stock. Aero Enterprises provides condition photos and grade confirmation before any purchase commitment.
