Origin Forging 316 Stainless Steel Shaft 304f Stainless Steel Bar AISI

1. Introduction

Forging stainless steel forgings produced by the impact of the oxide skin on the forging includes: 1, resulting in the loss of metal (also known as fire consumption), in forging or die forging, steel material each time, there are 1.5%-3% of the metal is oxidation burn;

2, reduce the surface quality of forging, forming such as oxide skin is pressed into the surface of forging, resulting in surface depression and affect the dimensional accuracy;

3. The surface of stainless steel forgings is attached with oxide skin, and the heat treatment will lead to the uneven structure and performance of the forgings;

4, reduce the service life of the mold, oxidized cortex hard and brittle, die forging will accelerate the wear of the forging die chamber, machining will accelerate the wear and damage of the tool;

5. The oxide skin is alkaline and falls off in the furnace, which will react with acidic refractory materials, and make the bottom of the furnace soft melting damage, shorten the life of the heating furnace;

6, the die forging to increase pickling or shot peening and other cleaning procedures, increase the cost of stainless steel forgings.
