The cold bending property of S690QL low alloy high strength steel plate is an important index for its mechanical propert

At the same time, the company operates a variety of products of related iron and S690QL low alloy high strength steel plate steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained S690QL low alloy high strength steel plate ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.

ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates are structural quality carbon steel plates just as S690QL low alloy high strength steel plate. ASTM A573 steel gardes are in three tensile strength ranges intended primarily for structural applications at atmospheric temperatures for which improved toughness is required.

The main advantage of 20CrMo alloy steel plate is reflected in its various physical and chemical properties. For 20CrMo alloy plate, the main component is alloy, and the physical and chemical properties of alloy S690QL low alloy high strength steel plate are generally, a single metal is better, and its performance is stronger. The main features of 20CrMo alloy steel plate are high precision, rigidity, high temperature and high pressure resistance, not easy to corrode and other characteristics.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the S690QL low alloy high strength steel plate steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the S690QL low alloy high strength steel plate weathering steel is purified and the content of inclusions is greatly reduced.

A131 EH36 steel is high strength marine grade hull structural steel. Its yield strength is no less than 355Mpa, tensile strength is 490-620 Mpa, and elongation is 19% min. S690QL low alloy high strength steel plate, EH36 steel strength is close to S355 steel. However, EH36 steel is shipbuilding steel, while S355 steel is carbon structural steel, and can not be certified by classification society. That is to say, S355 steel is not allowed to be used for ship building when there is certificate requirement. A131 EH36 steel is widely used to build ships working in low temperature water.
