17-7PH S17700 0Cr17Ni7Al Mainly Applicaiton
Offshore platforms, helicopter deck, other platforms, food industry, pulp and paper, aerospace (turbine blades), mechanical parts, barrels of nuclear waste 17-4PH alloy is a precipitation hardening martensitic stainless steel. 17-4PH alloy is a precipitation of copper, niobium / columbium constituted hardening martensitic stainless steel. This level has high strength, hardness (up to 300 & ordm; C / 572 & ordm; F)and anti-corrosion properties. After heat treatment, the mechanical properties of products more perfect,can reach up to 1100-1300 mpa (160-190 ksi) of compressive strength. This level can not be used above300 & ordm; C (572 & ordm; F) or under very low temperatures, its atmosphere and dilute acid or salt has good corrosion resistance, corrosion resistance and its 304 and 430 the same.
