Made from one of the most commonly used austenitic steels, added with titanium, the bars benefit from titanium, which minimizes carbide precipitation during welding and increases resistance to oxidation coming from air, water, or chemical environments. The excellent resistance in a wide range of corrosive media makes them industrially applied for long life with high performance under challenging conditions, more so in applications of shaping and machining.
SS 440B round bars offer good resistance to nitric and sulfuric acids and intergranular corrosion. They show excellent properties, including flexibility, durability, high ductility, outstanding strength, and high-temperature efficiency. Before dispatch to our clients, the SS 440B Round Bars undergo a series of tests that prove their quality and performance. The tests carried out are under international standards and customer requirements. Safe and efficient transportation comes with proper packing methods that ensure that our products are in good condition even while in transit
