Free Cutting Stainless Steel Sleeve St52 Forged Shaft Hot Forging Wear Resistant

1. Introduction

The deformation is too small after high temperature return to the furnace. Through the analysis of the causes and parts of the defects, the result of our analysis is that when the forging team is about to form these stainless steel forgings, they are installed back into the high temperature furnace for heating. After a short period of heat preservation (because the grain growth inside is not too serious), clamped out only flat end face, basically no rolling outer circle. As a result, the grains of a certain thickness on the inner and outer surfaces grow and merge at high temperatures. This defect can not be eliminated by heat treatment after forging (it is not that there is no defect near the inner and outer surface, but there is a flaw blind area under the probe). See the above defect cause analysis, we should understand: why repeatedly emphasize that the forging after a fire, never allow no deformation or small deformation.
