EN10025-3 S420N material is a welded low alloy steel grade. Its mateiral number is 1.8902. This steel shall be done low temperature charpy V impacting test under EN10025-3 standard, the temperature shall be -20℃, and the impacting energy shall be min 27J. For A572 grade 42 high strength steel, S420N steel plate quality, our company will supply various testing for our clients like size and quantity checking, the chemical analysis, ladle analysis, tensile test, impact test, and ultrasonic testing.
BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of A572 grade 42 high strength steel steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main A572 grade 42 high strength steel production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while A572 grade 42 high strength steel steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of A572 grade 42 high strength steel steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
The characteristic of niobium in A572 grade 42 high strength steel etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.
