FE2187 AISI 4150 Alloy Steel Round Bar

Description of AISI 4150 Alloy Steel Round Bar

SAE or AISI 4150 is a low‐alloy steel that contains chromium and molybdenum as strengthening agents. This steel alloy has a tensile strength of 731 MPa (106 000 psi), a defined wear resistance and a hardness of 197 HB as specified. It requires heat treatment prior to machining. The material is weldable and can be produced by conventional methods. Currently, AISI 4150 is used in the aerospace sector, in defence applications, in the oil and gas industry and in the automotive industry.
