When using A514 Gr B quenched and tempered steel, low-alloy high-strength steel, it is desirable to take advantage of its high strength and use a thinner section, not only for saving weight but also for the economy as much as possible. However, the corrosion factor must be fully considered. The thinner the steel section, the more attention should be paid to corrosion protection. Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but in some cases, take appropriate precautions and can even be used without being coated in the atmosphere.

Common A514 Gr B quenched and tempered steel, steel plate thickness specifications are as follows: Thick steel plate: thickness greater than 4, width within 10 is less than 2000mm, width above 10 is generally 2000, 2500mm, length 4-12m; Thin steel plate: thickness less than 4mm, width 500-1500mm, length 1.5-4m; Flat steel: thickness 4-60mm, width 12-200mm, length 3-9m.
In general, the global manufacturing industry has been seriously impacted by the epidemic, and the foreign epidemic is still in the outbreak period, and its A514 Gr B quenched and tempered steel demand recovery still has some time. However, the domestic epidemic situation has come to an end. In addition, the state has repeatedly stressed that the development of traditional infrastructure and new infrastructure needs a lot of steel. And now the return to work is getting better. As of March 20, the return rate of key projects is 89.1%, and the return rate of 11000 key projects in China is nearly 90%.
