2507 (UNS S32750) duplex stainless steel has strong strength and corrosion resistance, which is mainly used in chemical processing, petrochemical industry and subsea equipment. It has strong chloride corrosion resistance, high thermal conductivity and low coefficient of thermal expansion. The high content of chromium, molybdenum and nitrogen makes it highly resistant to patchy, crevice and general corrosion.

UNS S32760 is able to compete strongly with the 6% molybdenum “super austenitic” grades in some applications, as it has fewer amounts of Mo and Ni which drive up the base cost of the material. Although, 32760 has lower amounts when compared to “6% Moly” grades it still has higher contents of Cr, Ni, and Mo when referring to other alloys, these elements improve the intergranular and pitting corrosion resistance of the material.

Type 301 is an austenitic chromium-nickel stainless steel that is available in the annealed and cold worked conditions. In the annealed condition, Type 301 offers the highest level of stretch formability of any stainless steel and in the heavily cold worked condition offers the highest strength level of any 300 series stainless steel. Type 301 is non-magnetic in the annealed condition but becomes magnetic as a result of cold working.Type 301 is corrosion resistant in many environments, but the corrosion properties are less than that of 304/304L stainless steel.
