Alloy Steel
Alloy steel is a series of alloy which its main content is steel. To add different metal elements with different ratios in steel can change the mechanical properties of alloy steel.
Ju Feng holds stocks of alloy steel to meet the immediate needs of customers.
Adding one or more metal or non-metal elements to the base of ordinary carbon steel to change the mechanical and physical properties of carbon steel. Commonly added elements such as nickel, chromium, molybdenum, zirconium, vanadium, cobalt, aluminum Mn, tungsten, titanium, tantalum, etc., depending on the added elements, and appropriate processing, can obtain high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other special properties. After adding the element of alloy steel, the new steel is given the following main characteristics:
1. Strengthen the mechanical properties of steel, such as strength, hardness, impact value, toughness, elasticity, hardening energy and so on.
2. Extend the life of steel.
3. Increase the corrosion resistance and rust resistance of the steel to keep the surface of the steel bright and beautiful.
There are many kinds of alloy steels, usually divided into low alloy steel, medium alloy steel and high alloy steel according to the content of alloying elements; high quality alloy steel and special alloy steel according to quality; alloy steel, stainless steel, acid-resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, rolling bearing steel, alloy spring steel according to characteristics and application. According to special properties are divided into soft magnetic steel, permanent magnet steel, non-magnetic steel etc.
The most popular alloy steel is stainless steel with a chromium content of at least 10.5%. This ratio gives stainless steel better corrosion resistance and a layer of chrome oxide can slow rust. Generally, if the carbon content is reduced to 1% or 3%, the alloy metal can achieve higher formability and weldability, thereby increasing strength.
The main advantage of the alloy steel is for construction that it is easy to quench and improve the mechanical properties after tempering.
It is used to manufacture important parts of various machinery. It is excellent in various mechanical properties such as tensile strength, elastic limit, elongation, impact value and fatigue limit. At the same time, it has good and various processing properties such as castability, forgeability and machinability. It is mostly used in the manufacture of shafts, gears, strong screws, nuts, automotive, locomotive parts, mechanical parts, and surface hardening of various important mechanically parts.
