Stainless Steel

Stainless steel is a highly corrosion-resistant alloy primarily composed of iron, chromium, and varying amounts of nickel, molybdenum, and other elements. Its exceptional strength, durability, and resistance to rust and oxidation make it an ideal material for demanding applications across industries such as pharmaceuticals, food processing, chemical processing, marine, and architecture.

Available in various grades such as 304, 316, 310, and 321, stainless steel is tailored to meet specific performance requirements including heat resistance, hygiene, and mechanical strength. It offers excellent weldability, formability, and long service life even in extreme environments. Compliant with international standards like ASTM, ASME, and EN, stainless steel is essential to modern engineering and sustainable industrial solutions.

Available forms are Stainless Steel Pipes & Tubes, Stainless Steel Fasteners, Stainless Steel Sheet, Stainless Steel Plate, Stainless Steel pipe fittings, Stainless Steel flanges.
