What is S690QL1 high strength steel plates equivalent steel material in China

From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. S690QL1 high strength steel plates, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.

ASTM A572 Grade 50, used in large-scale construction, S690QL1 high strength steel plates is an extremely strong alloy with a yield strength of 65, 000 psi, an allowable bending stress of 39, 000 psi and a future as the high-performance replacement of ASTM A36 steel.

The company's S690QL1 high strength steel plates steel products are sold all over the world with high quality and low price. We can process and cut all kinds of special-shaped parts according to your requirements, or we can set and roll futures of all kinds of material specifications according to your requirements, with fast delivery time. We sincerely welcome new and old customers from all walks of life to contact us for S690QL1 high strength steel plates business negotiation.

The basic phases of S690QL1 high strength steel plates, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.
