Duplex alloy EN 1.4507

Steel EN 1.4507 / Alloy F255

1.4507 super duplex alloy is demanded in the industry stainless steel, which buy at affordable price the company offers. It is based on iron (around 67-68%), as well as additive and alloying components, including: • chrome; • molybdenum; • silicon; • manganese; • copper. This composition is distinguished by high mechanical strength, resistance to wear, durability. Steel 1.4507 – this anti-corrosion material, resistant to all types of moisture and aggressive environments (surface, crevice, pitting). Features and scope of use This steel grade has a low thermal expandability, it is simply welded (subject to technical conditions) and processed. High durability allows to use the alloy in remote locations where there is no possibility of the regular maintenance. The main application is the production of pipes, fittings, rods, wire for the oil gas industry. Also the alloy used in food and medical industry. If you need stainless steel, which price is available, and the quality complies with international standards, choose the raw material steel 1.4507. Our company offers a wide range of products from alloy of the type: pipe, wire, stainless steel rods (the price matches the quality).
