Stainless Steel

Stainless Steel is a highly versatile and durable alloy composed mainly of iron, chromium, and varying amounts of nickel and other elements. The addition of chromium provides excellent resistance to corrosion, oxidation, and staining, making it an ideal choice for a wide range of industrial and commercial applications.

At Mittal Overseas, we supply premium-grade stainless steel products that meet global quality standards, offering exceptional strength, durability, and a long service life. Our stainless steel materials are widely used in industries such as Oil & Gas, Petrochemical, Food Processing, Pharmaceutical, and Construction.

We offer stainless steel in various forms including Pipes & Tubes, Sheets & Plates, Bars & Rods, Flanges, and Fittings in multiple grades such as 304 / 304L, 316 / 316L, 310, and 321. Each product undergoes strict quality inspection to ensure superior performance and precision engineering.
