What is the difference between S355J2WP equivalent grade & Q235B?

The company is a leading company that sells S355J2WP equivalent grade steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold S355J2WP equivalent grade steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

ST52 steel angle steel with carbon content of 0.23% and yield point strength of 355 MPa is suitable for weldable and supporting members. In terms of chemical composition and mechanical properties, s355n is similar to S355J2WP equivalent grade en10025 - 3. Compared with ASTM A36, ST52 has higher strength and better welding performance. It is also used in daily life and industrial applications such as warehouses, equipment, etc. Note: although similar S355J2WP equivalent grade properties are shared, they are a little different. Please let us know your detailed requirements and we will tell you the most suitable steel grade.

Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate S355J2WP equivalent grade has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.

Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. S355J2WP equivalent grade, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.

The requirements for toughness impact energy of S355J2WP equivalent grade, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.

our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than S355J2WP equivalent grade 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.
