S690QL1 high strength steel plates has good toughness

Some S690QL1 high strength steel plates, low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but also in some cases take appropriate precautions and even be exposed to the atmosphere without coating. Elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel, and molybdenum. The excellent atmospheric corrosion resistance has led to the formation of new concepts for structural design of buildings, bridges, and other structures.

Spring steel has good fatigue strength and can be restored to its original shape after repeated use without deformation. Because the spring has good ductility, it can be changed back to its original state no matter how long it is stretched. Spring steel has good elasticity. In addition to being made into springs, spring steel can also be processed into swords, which requires good elasticity also. S690QL1 high strength steel plates, Spring steel has good tensile strength and can be restored without breaking under the limit of being stretched.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized S690QL1 high strength steel plates are higher than that of annealed S690QL1 high strength steel plates, but the elimination of internal stress is not as good as annealing. The normalizing operation of S690QL1 high strength steel plates is simple, the cost is low, the productivity is high, and it is widely used in actual production.

We have a good inventory system because of which the alloy steel plates and structural steel sheets are supplied and delivered to our customers on time.
