Super Duplex Steel 2507 is a super duplex stainless steel intended for applications which request uncommon quality and consumption resistance. Amalgam 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen substance brings about incredible imperviousness to chloride setting and hole erosion assault and the duplex structure furnishes 2507 with excellent imperviousness to chloride stress consumption splitting. Use of Duplex 2507 ought to be constrained to applications beneath 600° F (316° C). Developed lifted temperature introduction can decrease both the sturdiness and consumption resistance of compound 2507.
Super Duplex Steel 2507 has amazing mechanical properties. Regularly a light gage of 2507 material can be utilized to accomplish the same outline quality of a thicker nickel combination. The subsequent funds in weight can drastically decrease the general expense of manufacturers.
