Overview of 17-4PH stainless steel round bars:
17-4PH is a precipitation hardening steel material with high strength, high hardness, good welding performance and corrosion resistance. It has been widely used in valves, shafts and chemical fiber industries, and high-strength parts with certain corrosion resistance requiremen
17-4PH is a precipitation hardening martensitic stainless steel composed of copper, niobium/columb, with low carbon content, better corrosion resistance and weldability than general martensitic stainless steel, similar to 18-8 stainless steel, heat treatment process Simple and good machinability, but it is difficult to satisfy cryogenic processing.
Features: Precipitation hardening steel with copper added. Used in the manufacture of shafts and steam turbine parts.
Chemical Composition of Stainless Steel Grade 630 Round Bar:
17-4PH belongs to the chemical composition of precipitation hardening steel materials:
C: ≤0.07 Si: ≤1.00 Mn: ≤1.00 S: ≤0.030 P: ≤0.035 Cr: 15.50~17.50 Ni: 3.00~5.00 Cu: 3.00~5.00 Nb: 0.15~ 0.45
It has high strength, high hardness, good welding performance and corrosion resistance.
