Caliper Overseas is a reliable Stainless Steel 420 Bars Manufacturer and Supplier in India, providing high-quality bars for strength and durability. Stainless Steel 420 bars are made from martensitic stainless steel, which has high hardness, high wear resistance, and moderate corrosion resistance. The bars come in the forms of round, square and rectangular and are highly suitable for use where strong performance is required. SS 420 has a minimum of 12% chromium and increased carbon content, enabling it to be heat-treated to harden and increase strength and toughness.
These SS 420 bars are in accordance with international standards like ASTM A276, ASME SA276, and ASTM A479/SA479 to provide uniformity in quality and size. Black, bright polished, rough turned, matte and BA finish is provided. SS 420 bars are also supplied under UNS S42000, DIN 1.4021, ASTM A313 and BS 420S29 specifications. These multi-purpose bars are ideal for engineering and industrial purposes. Get in touch with us today for guaranteed supply and best price.
