ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates are structural quality carbon steel plates just as A514 Gr F alloy steel plate. ASTM A573 steel gardes are in three tensile strength ranges intended primarily for structural applications at atmospheric temperatures for which improved toughness is required.
Hot Rolled Plates Products TestingBBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the A514 Gr F alloy steel plate raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."
Since the outbreak of the new crown pneumonia epidemic this year, the Iron and Steel Association has closely followed and found that, with the exception of March, the production and operation of the steel industry has maintained a positive growth despite the low rate of resumption of work and production in other industries. Superimposed on the pull of a series of national policies in the later period, the steel industry effectively supported the development of the national economy.
The mechanical properties of hot rolled steel plate are far less than that of cold working and forging, but the A514 Gr F alloy steel plate, 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.
