Since it was established in 2000. Based on the domestic rich astm a581 spec product resources and the great steel demand of the international market, our astm a581 spec service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

BBN steel a professional cold rolled coils and galvanized steel sheets supplier in China. DC51D+AZ 55% AI-Zn galvanized steel sheet for appliances nominal thickness: 0.22~2.0; width: 700~1300; length of steel plate: 1000~6000; Inside diameter of steel strip: 508mm. It is mainly used for cold forming. With the alloy galvanized coating, the recommended nominal coating weight is 30/30, 40/40, 50/50, 60/60, 75/75, 90/90g/m².

Heat treatment advantages of astm a581 spec, SA516 Gr 70 pressure vessel steel:
1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased.
2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness.
3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition.
4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.

Vanadium is a weak deoxidizer. Adding vanadium into astm a581 spec steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

astm a581 spec, Chinese material Q235B is one of the most widely used carbon steel in the world. Some like to compare its strength with other equivalent steel grades. We need to take care that the Q235B steel strength varies with thickness. For the min. yield strength of Q235B steel plate: it is 235Mpa if thickness ≤16mm, 225 Mpa for thickness 16-40mm, 215 Mpa for thickness 40-60mm, 205 Mpa for thickness 60-100mm, 195 Mpa for thickness 100-150mm, 185 Mpa for thickness over 150mm. The tensile strength of Q235B steel plate is 375-500 Mpa.
