The company always adheres to the A572 grade 65 high strength steel principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great A572 grade 65 high strength steel cause. Customers are welcome to visit our company at any time. We are always ready to support you.
Under normal exposure to the atmosphere, A572 grade 65 high strength steel, bare steel forms a tight protective oxide film during the first few months of atmospheric corrosion. Sometimes architects choose bare steel structures because they want to get the appearance of uniform atmospheric oxidation on the steel surface, and sometimes they are to save the protective coating for economic purposes. To use these low-alloy high-strength steels in a bare state, the design must consider that the surface of the steel cannot be wet for a long time, and special attention should be paid to the special atmospheric environment to ensure that the corrosion rate of the steel is allowed under this condition.
Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, A572 grade 65 high strength steel and so on.
A small amount of Nb is sufficient to obtain excellent comprehensive properties of A572 grade 65 high strength steel etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
Our alloy steel plate and sheets are mainly used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service.Width: 1000mm to 4500mmThickness : 5mm to 150mmLength: 3000mm to 18000mmImpact tested 52° CA572 grade 65 high strength steel, Supply Condition: As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement.
