A588 grade A weathering steel plate application and heat treatment

Grade DH36 ship steel plate is a high-strength ship plate. Shipbuilding steel generally refers to the steel used for hull structure. It refers to the steel used for manufacturing the hull structure produced in accordance with the requirements of the classification society construction codes. A588 grade A weathering steel plate, DH36 ship steel plate is often ordered, scheduled, and sold as special steel. We can supply various sizes and shapes of ship steel like plates , steel angles, bulb flat, steel channel and section steel.

Since it was established in 2000. Based on the domestic rich A588 grade A weathering steel plate product resources and the great steel demand of the international market, our A588 grade A weathering steel plate 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

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 A588 grade A weathering steel plate, 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.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of A588 grade A weathering steel plate 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 company will accept the product quality objection registration record, pass it to the A588 grade A weathering steel plate production unit and relevant departments, and timely coordinate the supervision of product A588 grade A weathering steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
