Abstract
The invention discloses a lost foam 65Mn material. The lost foam 65Mn material comprises, by mass, 0.35-0.45% of C, 2.0-3.0% of Si, 0.5-0.7% of Mn, 8.0-10.0% of Cr, less than 0.05% of P, less than or equal to 0.02% of S and the balance Fe. Compared with the existing 65Mn material, the lost foam 65Mn material has good strength and can eliminate surface cracks.
Description
Technical field
The present invention relates to a kind of evaporative pattern 65Mn material.
Background technology
The carbon content of 65Mn steel is higher, has the advantages such as cheap, machinability is good, is used for fabrication tool, saw blade, spring, high-wearing feature part and various deep processed products etc., purposes widely, but shortcoming is intensity difference, crack sensitivity is large, easily produces surface crack.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of evaporative pattern 65Mn material.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of evaporative pattern 65Mn material, by mass percentage, its chemical composition is as follows: C 0.35 ~ 0.45%, Si 2.0 ~ 3.0%, Mn 0.5 ~ 0.7%, Cr 8.0 ~ 10.0%, P<0.05%, S≤0.02%, and surplus is Fe.
