38MnB5 grade steel is a micro alloy steel with added boron for enhanced hardenability. The material is capable of through hardening by quenching and tempering to produce tensile strengths of 1025 MPa (on limited sections) and achieves good wear resistance along with excellent mechanical loading performance.Welcome to come and Visit our factory.
