Caliper Overseas is a reputable manufacturer and supplier of Stainless Steel 420B Bars in India. We offer only the best-designed products for durability and performance. Stainless Steel 420B bars fall under the category of martensitic stainless steel, which is predominantly appreciated for its increased hardness and remarkable wear resistance. This grade possesses a higher carbon content as compared to the standard 420 stainless steel; hence, it is most ideal for those applications where mechanical strength is considerably enhanced. Referred to as 1.4028 or X30Cr13 in the designation system, these bars provide satisfactory resistance to corrosion in mildly aggressive environments.
These bars are made in compliance with international specifications like ASTM A276, DIN 1.4028, and EN 10088-3 for premium quality materials. These contain typical chemistry of 13% chromium and around 0.30% carbon to achieve properties like 800 MPa tensile strength, 650 MPa yield strength, and 245 HB hardness. The Stainless Steel 420B bars suit the sectors needing powerful and resistant corrosion products. Get your orders in now with reasonable price quotations and expedient dispatch.
