17-4ph Stainless Steel Bar

With the assistance of skilled and dedicated professionals, we are eminent Exporter and Supplier of 17-4ph Stainless Steel Bar in Wuxi, Jiangsu, China. 17-4PH alloy is a precipitation of copper, niobium / columbium constituted hardening martensitic stainless steel. This level has high strength, degree (up to 300A C / 572A F) and anti-corrosion properties. After heat treatment, the mechanical properties of the product more perfect, can reach up to 1100-1300 mpa (160-190 ksi) of compressive strength. This level can not be used above 300A C (572A 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.
