Welcome to BBN High Strength Steels Factory
In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.
Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the S890QL steel equivalent steel, and generally does not add a lot of alloy elements, sometimes it is also called ordinary carbon steel. Carbon steel refers to iron carbon alloy with carbon content of WC less than 2%. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus. According to the content of phosphorus and sulfur, the carbon steel can be divided into ordinary carbon steel, high quality carbon S890QL steel equivalent steel, high quality steel and super quality steel.
SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. S890QL steel equivalent, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
S890QL steel equivalent, Q345B low alloy plate performance: 1) High strength: Generally its yield strength is above 300MPa; 2) High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600kJ/m to 800kJ/m. For large welded components, higher fracture toughness is also required; 3) Good welding performance and cold forming performance; 4) Low cold brittle transition temperature; 5) Good corrosion resistance.
With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel S890QL steel equivalent product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue. We promise all our steel materials are manufactured and tested in accordance with responding standards. We will take full responsibility for the quality of the steel materials we provide.
