High-strength steel plate refers to the grade Q460 steel, which has high strength and has high comprehensive mechanical properties especially in the normalized or normalized and tempered state. Mainly used in large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts.
The strength is very high, much higher than that of ordinary steel plates, and it can withstand greater loads and pressures, making the building structure more stable and safer.High-strength steel plates also have very good toughness and are not easily broken when impacted or squeezed, thereby protecting the safety of buildings.The wear resistance and corrosion resistance are also very good, able to withstand the test in harsh environments and maintain a long service life.Trademark | grade | Chemical composition (mass fraction) (%) | ||||||||||
