20mm thick SPA-H plate for engineering and machine structural use

The company now has 20mm thick SPA-H plate oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than 20mm thick SPA-H plate 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

Although Q345E steel plate has stronger torsion resistance and better corrosion resistance than ordinary steel plate, there are still some environments that can cause corrosion to Q345E steel plate. The following environment should be avoided as far as possible to avoid corrosion of 20mm thick SPA-H plate, Q345E steel plate. 1. Acid water. 2. Salt water. 3. Nitric acid. 4. Atmospheric erosion. Atmospheric erosion for Q345E steel plate corrosion is reflected in the chloride and pollutant pollution source of Q345E steel plate corrosion, this corrosion is very serious.

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate 20mm thick SPA-H plate has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.

Manganese steel plate is a kind of common steel, which is a kind of high-strength anti manganese steel. 20mm thick SPA-H plate, Manganese steel plate is mainly used to bear the impact, extrusion, material wear and other severe working conditions. It is a typical anti-wear steel, with austenite and carbide as cast structure. After water quenching at about 1000 ° C, the structure changes into single austenite or austenite with a small amount of carbide.

The hardness of 20mm thick SPA-H plate, wear-resistant steel plate is an important standard to measure wear resistance. The hardness of wear-resistant steel plate can be divided into microhardness and surface hardness. The microhardness of carbide in the wear-resistant layer of wear-resistant steel plate can reach over HVl700-2000, and the surface hardness can reach HRC58-62. Chromium alloy is the main wear-resistant layer of wear-resistant steel plate, and other alloy components such as manganese, molybdenum, niobium, nickel are added at the same time.
