FAQ

Frequently Asked Questions

Is X5CrNi18-10 identical to 304 stainless steel?

Yes. X5CrNi18-10 is the official European EN designation (Werkstoff 1.4301), while 304 is the American ASTM code for the standard 18% chromium and 8% nickel austenitic alloy.

Why purchase from a direct 304 Stainless Steel Sheets & Plates Manufacturer in India?

Buying directly from a certified 304 Stainless Steel Sheets & Plates Manufacturer in India eliminates intermediary pricing, guarantees authentic factory test certificates (EN 10204 3.1 MTC), and allows custom cut-to-size shearing.

What surface finishes work best for food processing equipment?

2B, BA, and NO.4 (Brushed) finishes on Stainless Steel 304 Sheets & Plates are preferred for food-grade equipment because their smooth surfaces prevent bacterial buildup and simplify cleaning.

Can an X5CrNi18-10 Sheets & Plates Supplier in India provide laser-cut blanks?

Yes. As a full-service X5CrNi18-10 Sheets & Plates Supplier in India, we supply precision laser-cut circles, rings, and custom blanks based on your exact engineering drawings.

How do SS 304 Plates handle structural welding?

SS 304 Plates exhibit excellent weldability using standard TIG, MIG, and submerged arc methods, maintaining structural toughness across thin sheets and thick plates alike.

What is the corrosion resistance level of SS 304 in marine environments?

SS 304 offers excellent resistance to atmospheric corrosion and general seawater exposure. However, for highly aggressive saltwater applications, super austenitic grades like 6Mo or 254SMO are recommended.

Can I get custom thickness and size specifications from a 304 Stainless Steel Sheets & Plates Supplier in India?

Absolutely. As a dedicated 304 Stainless Steel Sheets & Plates Manufacturer in India, we offer full customization including thickness ranges from 0.3mm to 120mm and lengths up to 6000mm with precision edge cutting.
