Good translation Metal Products (Shanghai) offers stainless steel (made of stainless steel / stainless steel imports) 17-4PH stainless steel / 17-4PH steel / 17-4PH steel bars / 17-4PH steel coil / 17-4PH steel / 17-4PH steel / 17-4PH steel (good translation Metal Products (Shanghai) Co., Ltd.) 
 Introduction 
 17-4PH is a martensitic precipitation hardening stainless steel .17-4PH performance characteristics are easy to adjust the intensity level can be adjusted by changes in heat treatment process (process towards the development of the Shanghai company specializes in metal). Martensitic transformation and aging dealing with the formation of precipitation hardening is the main means of strengthening ,17-4PH attenuation performance, corrosion fatigue and anti-drop performance strong. 
 17-4PH alloy is a precipitation hardening, martensitic stainless steel, and this level has a high strength, hardness and corrosion resistance properties. After heat treatment, the mechanical properties of the product more complete, can reach up to 1100-1300 mpa (160-190 ksi) of compressive strength. This class can not be used above 300 ℃ (570F) or very low temperatures, dilute acid or its salt air and has good corrosion resistance, corrosion resistance and its 304 and 430 the same.
