What is the carbon steel hardox 500 plate equivalent of GB material

we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.

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.

The Performance requirements of low alloy structural steel, carbon steel HARDOX 500 plate:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

Our client purchase more than 900 tons pipe carbon steel HARDOX 500 plate from India. And we do the inspection for each one pipe before shipment.During the inspection, the inspector saw that the surface of the square pipe kept the original color of the stainless steel, no fracture, no depression and other quality defects was found.
