What are the classifications of A633 grade C carbon steel plate sheet

Since it was established in 2000. Based on the domestic rich A633 grade C carbon steel plate sheet product resources and the great steel demand of the international market, our A633 grade C carbon steel plate sheet service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

Structural steel S355JR, S355J0, S355J2G, S355J2G4 are low-alloy high-strength structural steels that comply with the European standard EN10025. S355JR steel in China is a low-alloy high-strength structural steel with a hardness of 70-80B and a yield strength of 300-400MPa. S355J2G3 steel is roughly equivalent to GB Q345D. S355J2G3 means that the delivery state is normalized, and the impact energy at -20°C is 27J. G3 and G4 mean the deoxidation method.

SA516 gr.60 boiler plates are primarily intended for use by pressure vessel fabricators and manufacturers. And, physical and chemical characteristics of the boiler quality plates make these a popular choice in the industries. SA516 gr.60 boiler steel plates are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built. Also, these plates A633 grade C carbon steel plate sheet are repellent to corrosion and therefore is long-lasting and can also be used in different environments for a long time without any deterioration.

Vanadium mainly exists in the form of carbide in A633 grade C carbon steel plate sheet and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

The requirements for toughness impact energy of A633 grade C carbon steel plate sheet, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.
