S355J2WP equivalent astm grade factory price list

The mechanical properties of hot rolled steel plate are far less than that of cold working and forging, but the S355J2WP equivalent astm grade, hot rolled steel plates have better toughness and ductility. Cold rolled steel plate has a certain degree of work hardening and toughness is low, but it can achieve a better yield ratio, and can be used for cold bending spring leaf and other parts. At the same time, because the yield point of cold rolled steel plate is close to the tensile strength, the danger is not foreseen in the use process, and accidents are prone to occur when the load exceeds the allowable load.

With the development of China's S355J2WP equivalent astm grade market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of S355J2WP equivalent astm grade products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

Most common S355J2WP equivalent astm grade steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled S355J2WP equivalent astm grade steel plates.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of S355J2WP equivalent astm grade nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of S355J2WP equivalent astm grade steel, can be used as an alloying element of low alloy steel.
