EN steel grade S235J0 plates H beams

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

The quality of carbon steel is distinguished by the amount of sulfur (s) and phosphorus (P) in the steel. When the EN steel grade S235J0 plates sulfur content in carbon steel is not more than 0.050% and the phosphorus content is not more than 0.045%, it is ordinary carbon steel; when the sulfur content and phosphorus content in carbon steel are less than 0.040%, it is high-quality carbon steel; when the EN steel grade S235J0 plates sulfur content in carbon steel is less than 0.030% and the phosphorus content is less than 0.035%, it is high-quality carbon steel.

EN steel grade S235J0 plates,Q345R material is a special steel grade for pressure vessels with a yield strength of 340MPa. It has good comprehensive mechanical properties and technological performance. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 (16Mn) steel. In addition to the increased tensile strength and elongation requirements compared to Q345 (16Mn) steel, it also requires impact toughness. Q345R steel plate is currently the most widely used and most used steel plate for pressure vessels in China.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.EN steel grade S235J0 plates
