Which Q355GNH steel plate is the best?

Q355GNH steel plate,In production and operation, the company always attaches great importance to product quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.

The alloy steel plates are among our main steel products. There are various alloy steel grades on the market. The most popular alloy steel materials are European material under EN10083-3 and Chinese material under GBT3077 for round bars and GBT11251 for plates. Our typical alloy steel grades are 51CrV4, 25CrMo4, 34CrMo4, 42CrMo4, 12Cr1MoV, 20Cr, 40Cr, 15CrMo, 30CrMo, 35CrMo, 42CrMo, etc.

Q355GNH steel plate,42CrMo steel plate is an ultra-high strength steel plate, which is widely used in machinery manufacturing steel The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness 42CrMo steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low temperature impact toughness,Q355GNH steel plate.

After adding a small amount of niobium, vanadium and titanium to the steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

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. SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
