Density for SS 304 weight calculation: 7,930 kg/m³ (7.93 g/cm³) — NOT the MS value of 7.85. Using 7.85 for SS 304 gives a 1% undercount, significant on large orders. Formula: Weight (kg) = L (m) × W (m) × T (mm) × 7.93. Thickness range in India: 0.5 mm to 80 mm for sheet/plate. Most common stocked thicknesses: 0.5, 0.6, 0.8, 1.0, 1.2, 1.5, 2.0, 2.5, 3.0, 4.0 mm.

* For a 10 MT SS 304 order using MS density (7.85) instead of 7.93: undercount = 10,000 × 1% = 100 kg error. At ₹220/kg for SS 304, that's ₹22,000 under-quoted per 10 MT order. Always use 7.93 for SS 304.

SS 304 Sheet Finish Types — India Stocking Guide

Standard surface finishes available from Indian SS 304 suppliers — IS 6911 and ASTM A240 finish designations

Standard Cold Rolled Bright

Cold rolled, heat treated, pickled, then skin passed on polished rolls. Smooth, moderately reflective, grey-silver appearance. Most widely stocked SS 304 finish in India.

Chemical tanks, food equipment, general fabrication, architectural panels

⭐ Most Common in India

Cold Rolled Dull

Cold rolled, heat treated, pickled — not skin passed. Dull, matte silver appearance. Better forming characteristics than 2B as the rough surface holds lubricant during deep drawing.

Deep drawn parts, utensil blanks, sinks, forming operations

Common

No.1

Hot Rolled Annealed Pickled

Hot rolled, annealed and pickled. Rough, dull, non-uniform surface. Only available in thicker gauges (3mm+). Less expensive than cold rolled. Not aesthetically finished.

Industrial tanks, structural applications, non-visible surfaces, pressure vessels

Thicker Gauges Only

Bright Annealed

Cold rolled, annealed in a protective atmosphere (no oxidation), then slightly skin passed. Bright, highly reflective, near-mirror finish. More expensive than 2B.

Decorative panels, appliances, elevator interiors, premium kitchen equipment

Premium Finish

No.4

Brushed / Satin Finish

Ground with 120–180 grit abrasive belt, producing a unidirectional linear grain texture. Most widely specified decorative finish worldwide and in India. Available with PVC film protection.

Kitchen countertops, equipment panels, handrails, food processing, catering equipment

⭐ Popular Decorative

No.8

Mirror / Polished

Buffed to a high mirror reflectance with no visible grain. Ra surface roughness <0.1 µm. Maximum reflectivity. Usually supplied with PVC protective film in India.

Decorative cladding, signage, elevator doors, architectural features, displays

Premium / Decorative

Hairline Finish

Ground with very fine 240+ grit abrasives to produce long, continuous, parallel polishing lines. Elegant appearance widely used in Indian architectural SS applications.

Architectural cladding, lift doors, building facades, interior design panels

Premium / Architectural

Matt PVC

Matt Finish with PVC Film

Matte surface finish (No.4 equivalent) with a PVC protective film applied on one or both faces. Very common from Jindal Stainless India — PVC film protects surface during transit and fabrication.

Kitchen equipment, fabrication where surface protection during forming/welding is needed

⭐ Jindal Standard

Weight note: Surface finish does NOT change the sheet weight — a 2mm 2B and a 2mm Mirror finish sheet weigh exactly the same (15.86 kg/m²). However, remove PVC film before weighing or comparing to IS 6911 thickness tolerance tables — PVC adds ~0.05–0.1 kg per m² and is not structural material.

SS 304 Procurement Tips — India 2026

Always Use 7.93 — Not 7.85 for SS 304

The 1% density difference between SS 304 (7.93) and MS (7.85) compounds significantly on large orders. A 50 MT SS 304 order estimated at 7.85 is 500 kg short — at ₹225/kg that's ₹1.1 lakh in underbilling. Set 7.93 as a fixed constant in all SS 304 estimating templates.

Jindal Stainless — India's Primary SS 304 Maker

Jindal Stainless Ltd (Hisar, Haryana) is the dominant domestic producer of SS 304 sheet in India. Standard sizes are 2500×1250 and 3000×1500 mm with 2B and Matt PVC finishes. For imported material (Korean, Taiwanese coil), size tolerance and finish may differ from Jindal — always check the MTC for actual thickness.

IS 6911 Thickness Tolerance is Tighter Than MS

IS 6911 (SS sheets) has tighter thickness tolerances than IS 1079 (HR MS). For 2mm CR SS 304: IS 6911 allows −0.05/+0.11 mm. For 2mm MS HR (IS 1079): ±0.16 mm. SS measurements are more consistent — a good reason to use actual MTC thickness for precision weight calculations.

Verify Grade on MTC — 202 vs 304 Fraud

In India, SS 202 (a lower-cost, lower-nickel grade) is sometimes supplied in place of SS 304. The visual appearance is nearly identical — the only reliable check is the Mill Test Certificate (MTC) showing chemical composition (Ni ≥8% for 304 vs ≤5% for 202) or a PMI (Positive Material Identification) test using an XRF gun. Density: 202 = 7.75 vs 304 = 7.93.

Ordering in mm — Not Gauge for SS

Always specify SS 304 sheet orders in mm, not gauge numbers. SWG gauge values do not correspond neatly to the standard metric thicknesses (0.5, 0.8, 1.0, 1.2 mm) that Jindal produces. Write "1.0 mm SS 304 2B IS 6911" — not "20 SWG" — on every PO. Gauge confusion in SS is one of the most common causes of incorrect material delivery in India.

SS 304 Price Fluctuates with LME Nickel

SS 304 prices in India are directly linked to LME (London Metal Exchange) Nickel prices — nickel is ~8% of SS 304 by weight and is the most expensive alloying element. When nickel prices rise, SS 304 sheet prices follow within 2–4 weeks. Lock in prices on large procurement orders or request price validity on quotations — typically valid 7–15 days from Indian SS service centres.

FAQ — SS 304 Sheet Sizes & Weight India

What is the standard size of SS 304 sheet in India?

The most common standard sizes of SS 304 sheet stocked in India are 2500×1250 mm and 2000×1000 mm for sheet, and 3000×1500 mm for the large format. Jindal Stainless (the primary Indian manufacturer) produces 2500×1250 mm as their standard cut sheet size. The 4ft×8ft (1219×2438 mm) size is also quoted by traders, particularly for older job specifications. Sheets outside these standard sizes are available as custom cut from service centres in Mumbai, Delhi, Ahmedabad, Chennai and Coimbatore — usually at a premium of ₹5–15/kg over standard size pricing.

What is the weight of a 1mm SS 304 sheet (2500×1250 mm) in India?

A 1mm SS 304 sheet, 2500×1250 mm, weighs 24.8 kg (theoretical).

Formula: 2.5 × 1.25 × 1.0 × 7.93 = 24.78 kg ≈ 24.8 kg

Note: Jindal's published weight tables use 8.0 g/cm³ (rounded), giving 25.0 kg for the same sheet. The difference is 0.2 kg (0.8%) — negligible for single sheets but adds up on large orders. Use 7.93 for precise estimates and 8.0 if cross-referencing Jindal's official weight charts.

What is the weight of a 2mm SS 304 sheet (2500×1250 mm)?

A 2mm SS 304 sheet, 2500×1250 mm, weighs 49.6 kg (theoretical at 7.93 g/cm³).

Formula: 2.5 × 1.25 × 2.0 × 7.93 = 49.56 kg ≈ 49.6 kg per sheet

Sheets per metric tonne: 1000 ÷ 49.6 = 20.2 sheets/MT. For 3mm: 74.3 kg/sheet (13.5 sheets/MT). For 1.5mm: 37.2 kg/sheet (26.9 sheets/MT).

Which is better for Indian fabrication — SS 304 2B or No.4 finish?

Depends entirely on application:

SS 304 2B — choose for: tanks, pressure vessels, chemical equipment, structural fabrication, non-visible surfaces, any application where appearance is not primary. 2B is cheaper, better corrosion resistance data, widely stocked, takes welds and bends predictably.

SS 304 No.4 Brushed — choose for: commercial kitchens, food processing equipment, hospital/pharma surfaces, customer-visible panels, counter tops and cabinets where hygiene and aesthetics both matter. No.4 is easier to maintain — scratches are less visible and surfaces clean easily.

Weight is identical for both at the same thickness. Price difference: No.4 typically costs ₹15–25/kg more than 2B in India for the same grade and thickness.

How do I check if an SS 304 sheet is genuine (not SS 202)?

Three methods used in India:

1. MTC check: Request the Mill Test Certificate — nickel content must be ≥8.0% for SS 304. SS 202 has ≤5.5% nickel. This is the most reliable method and should be standard practice for all SS procurement.

2. PMI (XRF gun): Positive Material Identification using a portable X-ray fluorescence (XRF) analyser. Many Indian inspection agencies and large fabricators have these. XRF reads the chemical composition of the surface in seconds. Cost: ₹500–2000 per test point from NABL inspection agencies.

3. Magnet test (limited): SS 304 in annealed (sheet) condition should be only weakly magnetic or non-magnetic. SS 202 is also weakly magnetic. However, cold working during rolling makes both grades slightly magnetic — this test is unreliable for confirming grade.

Never accept SS 304 without MTC from the original mill (Jindal, SAIL, or named import coil manufacturer). Trader-only invoices without MTC are a red flag.
