SA633 grade E carbon steel plate sheet mild steel I beams

ASTM A514 steel is mainly used in places where high tensile strength and high yield are required, such as engineering vehicle lifting gears, large excavators, offshore platforms, etc. Different grades of A514 steel plate have different thickness, chemical composition and properties. However, the SA633 grade E carbon steel plate sheet mechanical properties specified in ASTM A514 are similar to those of Q690 in China. A514 grade Q is generally used as the rack for offshore platform. Its hardness is between 230-390MPa, yield is greater than 630MPa, and tensile strength is more than 700MPa.

Our company was founded in 2000, which initially committed to providing high-quality steel SA633 grade E carbon steel plate sheet products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export SA633 grade E carbon steel plate sheet steel to the international market, opening up the international steel market.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of SA633 grade E carbon steel plate sheet, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

The characteristic of niobium in SA633 grade E carbon steel plate sheet etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
