50Mn2V steel round bar

50Mn2V steel round bar has stable composition uniformity and low inclusions. 50Mn2V steel round bar has high carbon and alloy content,after forming and suitable heat treatment,the hardness of the steel will be very high,which meets the requirements to make die-cutting and saw blades.

50Mn2V steel round bar supplied by a steel-making plant for saw blade matrix had poor hardenability,such as non-uniform hardness and large deformation,after being quenched.The reason of bad hardenability for the 50Mn2V steel round bar was analysed by chemical composition analysis and microstructure observation.The results show that the bad hardenability of the 50Mn2V steel round bar was because of the microstructure defects in the supplying sheets including obvious banded microstructure,net ferrite and bulky pearlite microstructure,and the defects were resulted from the abnormal continous casting process.The hardenability of the 50Mn2V steel round bar could be improved by optimizing the corresponding continous casting parameters,such as liquid super-heating extent,the secondary cooling degree and the uniformity of cooling water.
