Stainless Steel Coil Price
The price of stainless steel coils in India ranges from about ₹188 to ₹208 per kg. While in international markets, they are generally around $2.25 to $2.50 per kg. Price varies based on factors such as grade, thickness, width, surface finish, order volume and current raw material surcharges. Extra charges for nickel, chromium, and molybdenum set by major mills directly affect the final price of coils. Hot rolled (HR) coils are usually 5-10% more cost-effective than cold rolled (CR) coils of the same grade and thickness. Share your specifications with us for up-to-date, project-specific pricing. We offer coils in all grades and provide flexible minimum order quantities at competitive prices.
Applicable Standards for Stainless Steel Coils
Flat-rolled stainless steel coils conform to several international standards depending on the target market and application.
| Standard | Scope |
|---|---|
| ASTM A240 / ASME SA-240 | Plate, sheet, strip for pressure vessels and general use |
| ASTM A666 | Austenitic sheet, strip, plate |
| ASTM A480 / ASME SA-480 | General requirements for flat-rolled stainless |
| IS 6911 | Stainless steel plate, sheet, strip |
| EN 10088-2 | Corrosion-resisting steels for general purposes |
| JIS G 4304 / JIS G 4305 | HR and CR stainless steel plate, sheet, strip |
| GB/T 4237 / GB/T 3280 | HR and CR stainless steel plate, sheet, strip |
Stainless Steel Coil Grades
Stainless steel coils are produced in grades 304, 316 and 430. Choosing the right grade depends on the material used, the required resistance to corrosion and the budget.
Stainless Steel 304 Coils (HR & CR)
SS 304 Hr and CR coils contain 18% chromium and 8% nickel. Good general corrosion resistance. Used in fabrication, kitchen equipment, tanks and piping. Suitable for normal atmospheric and mild chemical environments.
Stainless Steel 316 Coils (HR & CR)
316 stainless steel HR and CR coils include molybdenum, giving them stronger resistance to corrosion in chloride environments. They perform better than 304 in tough, high-temperature conditions and are commonly used in marine, chemical, and pharmaceutical applications.
Stainless Steel 430 Coils (HR & CR)
430 SS hot-rolled and cold-rolled coils are ferritic stainless steel with chromium content around 16–18%. Moderate corrosion resistance. Used in appliances, automotive trim and indoor applications. Lower cost compared to austenitic grades.
Stainless Steel Coil Types
Stainless steel coils are produced in 3 main types, called hot rolled (HR), cold rolled (CR) and slit coils. Each type serves different downstream processing needs.
Stainless steel Hot Rolled (HR) Coils
Stainless Steel Cold Rolled (CR) Coils
Stainless Steel Slit Coils
Stainless Steel Coil Applications
Stainless steel coils serve 5 major industry sectors mentioned below. Grade and finish selection depend on the specific application environment.
Automotive & Transportation
304 and 430 coils serve in trim, structural components, and fuel tank straps.
Construction & Architecture
Coils in grades 304 and 316 are used for roofing, cladding, curtain walls, and structural supports. Grade 430 with a polished finish is used in decorative panel work.
Food Processing & Kitchen Equipment
For food-contact uses, 304 or 316L stainless steel coils with a 2B or BA finish are preferred. These grades withstand frequent cleaning with both acidic and alkaline cleaners.
Chemical & Petrochemical Processing
Grade 316 coils handle chloride-bearing and acidic process streams. Vessel linings, heat exchanger plates, and reactor components are common uses.
HVAC & Heat Exchangers
Stainless steel coils in grades 304 and 316 are formed into fin stock, tubing shells, and ductwork components for heating, ventilation, and cooling systems.
Hot Rolled vs Cold Rolled Stainless Steel Coils
The table below displays the key differences between HR and CR stainless steel
| Property | Hot Rolled (HR) | Cold Rolled (CR) |
|---|---|---|
| Processing Temperature | Above recrystallisation | Below recrystallisation |
| Thickness Range | 2.0-12 mm | 0.3-4.0 mm |
| Surface Finish | No. 1 (HRAP), rough | 2B, BA, polished |
| Dimensional Tolerance | Wider tolerances | Tighter tolerances |
| Cost | Lower | Higher |
| Applications | Structural, industrial | Precision stamping, decorative |
HR coils are the more cost-effective option for structural fabrication, while CR coils are better for applications requiring tight tolerances and smooth finishes.
