Stainless Steel Square Bar-15-5 PH

According to the production process, stainless steel rods can be divided into three types: hot rolling, forging and cold drawing. The specification of hot rolled stainless steel round bar is 5.5-250 mm. Among them: 5.5-25mm small stainless steel round bars are mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25mm are mainly used for the manufacture of mechanical parts or as seamless steel pipe billets .

15-5 PH Stainless Steel Rod - AMS 5862 - UNS S15500
15-5 stainless steel is a martensitic precipitation hardening material containing chromium, nickel and copper. It is often the first choice for fasteners and structural components in the aerospace industry. Its unique structure provides higher toughness and better corrosion resistance than its predecessor, 17-4 PH. Inclusion control and minimal delta ferrite contribute to the toughness of 15-5 compared to 17-4 stainless steel. The alloy is further strengthened by a low temperature heat treatment which precipitates a copper-containing phase in the alloy. 15-5 PH is capable of meeting the stringent mechanical properties required by the aerospace and nuclear industries. It is also widely used in the food processing, paper and general metalworking industries.
Alloy 15-5 is a precipitation hardening alloy with high strength and hardness and moderate corrosion resistance. Alloy 15-5 is a variant of the older 17-4 and 15-5 alloys and is designed to have higher toughness than S17400, especially in the through-thickness (short transverse) direction. Alloy 15-5 is used in applications requiring high transverse strength and toughness, such as engine components, aircraft components, nuclear reactor components, etc.
