Home > Stainless Steel > Stainless Steel Garde > 201 Stainless Steel
201 stainless steel is an austenitic, chromium-nickel-manganese alloy specifically designed as a cost-effective alternative to 304 and 301 grades, offering similar corrosion resistance and mechanical strength. Due to its lower nickel content, this grade is economically advantageous, maintaining essential properties for applications in moderately corrosive environments. Solitaire Steel & Engineering LLP, located in Mumbai, India, specializes in 201 stainless steel products, supplying them in various forms like sheets, plates, pipes, tubes, bars, angles, channels, beams, and fittings, meeting high-quality standards such as ASTM A240, ASTM A666, and ASME SA240.
