The strength and shortcomings of hardness of nm450 sheet

In the final analysis, the market competition is the competition for customers. Whether selling products or services, the final customer satisfaction is the standard to test the success or failure of marketing work. The so-called after-sales service is to fully understand customers, study customer psychology, pay attention to after-sales details, improve work shortcomings, improve service quality, and Exchange customer brand loyalty through the whole process of quality service.

GJB/1496A-2000 this standard uses and manufactures 28Cr2Mo steel plates with thicknesses of 10, 12, 15, 20, 25, 30mm for armored vehicles, and 26SiMnMo steel plates with thicknesses of 5, 6, 8, 10, 12, 15, 20mm and thicknesses. 28Cr2Mo is armored bullet-proof steel, code-named GY4. It is the main protective device on the tank. It needs to have high elasticity resistance. It also needs to have good processing technology and welding performance to meet the requirements of the tank manufacturing industry.

For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The hardness of NM450 sheet, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.

Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of hardness of NM450 sheet metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.
