Nandini Steel is a trusted 304L stainless steel sheet manufacturer and supplier in Mumbai, India. We supply ASTM A240 / ASME SA-240 Type 304L stainless steel sheet (also known as UNS S30403 / AISI 304L / SS 304L sheet) in a complete range of thicknesses, widths, and surface finishes. Our low‑carbon 304L stainless steel sheet offers strong corrosion resistance, easy welding without post‑weld heat treatment, and good formability for a wide range of industrial applications.
This 304 low-carbon stainless steel sheet belongs to the austenitic family and contains 18.0-20.0% chromium and 8.0-12.0% nickel, with carbon restricted to 0.030% maximum. That reduced carbon level is the defining characteristic of the “L” designation. Our 304L stainless steel sheet meets a minimum tensile strength of 485 MPa (70 ksi) and minimum yield strength of 170 MPa (25 ksi), with elongation of at least 35%. This grade resists intergranular corrosion after welding, so it is often chosen for fabricated parts used in corrosive environments. We stock 18-8 low‑carbon stainless steel sheet from 0.1 mm to 100 mm thick, up to 2,500 mm wide, and in standard 4×8 ft sheets. Finishes include 2B, BA, No.1, No.4, and mirror (No.8). Custom cut-to-size options are available on request.
All sheets conform to ASTM A240 and ASME SA-240 standards. We supply customers in the food processing, chemical processing, pharmaceutical, architectural, and oil and gas sectors. Nandini Steel is an ISO 9001-certified organisation.

Frequently Asked Questions
What is the difference between 304 and 304L Stainless Steel Sheet?
304L stainless steel has less carbon than 304, so it welds better and keeps its corrosion resistance. Standard 304 may lose corrosion resistance in welded areas unless heat-treated after welding. For welded sheet fabrications, 304L is the preferred choice.
Can 304L Stainless Steel Sheet be welded without post-weld annealing?
Yes. 304L stainless steel sheet’s low carbon content (0.030% maximum) prevents carbide precipitation during welding. Post-weld annealing isn’t required for most applications. This is one of the main reasons fabricators select 304L over standard 304 for welded assemblies, storage tanks, and process equipment.
What finishes are available for 304L Stainless Steel Sheet?
304L stainless steel sheet is available in 2B, BA, No.1, No.4, and mirror (No.8) finishes. 2B is the most common finish for general-purpose use: cold rolled, heat treated, pickled, and skin passed. BA (bright annealed) offers a reflective surface without mechanical polishing. No.4 provides a brushed satin texture. Mirror finish (No.8) is used for decorative and architectural work.
What is the maximum service temperature for 304L Stainless Steel Sheet?
What Standard Sizes are available for 304L SS Sheet?
Standard 304L SS sheet sizes are 4 ft x 8 ft (1,220 mm x 2,440 mm), 5 ft x 10 ft (1,500 mm x 3,000 mm), and 1,250 mm x 2,500 mm. Thicknesses range from 0.1 mm to 100 mm. We also supply custom-cut-to-size sheets per client specification.
Is 304L Stainless Steel Sheet magnetic?
304L stainless steel sheet is not magnetic when it has been annealed. If it is cold worked (bent, rolled, or formed), it can become slightly magnetic because of changes in its internal structure. Heating it again with a full anneal removes this effect and makes it non-magnetic again. For applications requiring confirmed non-magnetic behaviour, specify annealed-condition material and verify with a permeability test.
How much does a 4x8 Sheet of 304L Stainless Steel cost?
A 4×8 ft sheet of 304L stainless steel ranges from ₹190 to ₹350 per kg in India, and $1.50 and $3.00+ per kg in USD. Final cost depends on thickness, surface finish, quantity ordered, and current nickel/chromium market rates. Contact Nandini Steel for a current quote.
What is the weight of 304L Stainless Steel Sheet per square meter?
The weight of a 304L stainless steel sheet per square metre depends on the thickness. With a density of approximately 8,000 kg/m3, a 1 mm thick sheet weighs about 8 kg/m2. A 2 mm sheet weighs approximately 16 kg/m2, and a 3 mm sheet comes to roughly 24 kg/m2. Multiply thickness (in mm) by 8 to calculate the weight per square metre for any gauge.
What is the price of 304L Stainless Steel Sheet?
304L stainless steel sheet price in India starts from ₹190 and goes up to ₹350 per kg, depending on thickness, finish, quantity, and current market conditions. International pricing is from USD $2.50 to $5.00 per kg.
