The SS 440A Round Bars offer excellent resistance to corrosion, rust, acids, and alkalized solutions for various industries. They show high mechanical strength and flexibility, coupled with robust resistance to pitting, chloride stress corrosion cracking, and cracking corrosion at temperatures as high as up to 1000°F.
Hardness and strength further raise their utility in the most demanding settings. Widely used in industries like petrochemical, oil and gas, heat exchangers, automobiles, textiles, fertilizers, pharmaceuticals, specialty chemicals, off-shore oil drilling, food-processing, power generation, pulp and paper, pharmaceutical equipment, seawater equipment etc,. SS 440A Round Bars are subjected to various tests to ensure quality standards that involve Hardness Test, Chemical Composition Test, Mechanical Properties Test, Positive Material Identification test, and many others to make sure that the product is perfect. We provide them with a wide range of packaging options, from wooden boxes to plastic ones, and customized solutions as per their specific needs.
