Forging Square Stainless Steel 3mm 17 4ph Hot Rolled Forged Steel Shaft

1. Introduction

The deformation resistance of stainless steel at high temperature is relatively large, therefore, forging stainless steel needs to use a larger tonnage of equipment and wear resistant mold materials. The high temperature resistance of stainless steel is between nickel-based superalloy and general alloy structural steel, and the surface rises with the increase of the deformation degree, so too much deformation degree can not be used.
