Product Description

Introduction

In addition to iron and carbon, other alloy elements are added to alloy steel, which is called alloy steel. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. According to the different added elements and adopting appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance and non-magnetism can be obtained.
