Alloy steel plate is a steel plate made by adding or using some alloy elements based on high quality steel, such as aluminum, zinc, chromium, etc.
Alloy steel plate product characteristics: has high strength and good toughness, with good overall mechanical properties.
Alloy steel plate is mainly available in two types: general alloy and special alloy, of which general alloy can be divided into two types: general alloy and special alloy.

Because of the good processing performance of alloy steel plate, it can be processed for various complex parts, so it is widely used in automobile, tractor, motorcycle, aircraft and ship industries.
1、Alloy steel plate products are widely used in shipbuilding, automobile manufacturing, bridge construction, construction industry and other fields.

2, alloy steel plate products are mainly specifications, of which the largest variety of specifications, the largest amount of hot-rolled alloy steel plate varieties, followed by cold-rolled alloy plate species, accounting for more than 65% of all applications.

3, alloy steel plate according to the carbon content can be divided into low carbon (with Mo) steel, carbon (C Si) steel and high carbon (C S) steel three.

4, alloy steel plate has excellent mechanical properties, can be widely used in a variety of harsh environments, the use of temperature range -40 ℃ to +150 ℃, can be made to withstand the larger impact of mechanical parts and aircraft landing gear in.

5, alloy steel plate has good toughness and welding properties in the temperature range of -40℃ to +150℃.

6, alloy steel plate welding performance is good, and after welding without heat treatment can be plastic processing, easy to achieve welding and mechanical processing.

7、After the low temperature impact, its internal structure is not damaged and still maintains the original performance.

8, alloy steel plate has good welding performance, suitable for structural members and complex members of the welding process.

Alloy steel plate is a steel made by adding alloying elements to high-strength steel.

[1] classified by chemical composition: alloy steel plate has ordinary alloy steel plate, heat-resistant alloy plate and special stainless steel plate.

[2] Classified by mechanical properties: there are low-tensile alloy steel and high-tensile alloy steel.

[3] classified by application: there are low flexural strength ratio (L/S) high strength (H/S) alloy steels for building structures.

[4] classified according to carbon content: there are carbon structural steels (containing manganese), carbon-free structural steels (containing manganese and sulfur), etc.

The surface of alloy steel plate can be heat-treated or chemically treated to improve strength and toughness.
(1) Alloy steel plate surface after heat treatment or chemical treatment, its steel plate surface can maintain the same physical and chemical properties as the original metal material, and can improve its service life.

(2) the chemical composition of alloy steel plate and the original metal material without change, and can improve the weldability.

(3) The organization structure of alloy steel plate can be changed by heat treatment or chemical treatment, and it is possible to form a certain range of organization, such as grain refinement or pearlite phase generation.

(4) In the heat treatment and chemical treatment, the alloy steel plate compared with the original metal material strength and toughness increased by about double.

(5) In heat treatment or chemical treatment, the performance of alloy steel plate in welding, bending resistance, etc. can be improved.
