Hot sales material 1.8909

Compared with 12CrMoV steel, material 1.8909, 12Cr1MoVR pressure vessel steel has higher oxidation resistance and heat strength. The creep limit of this steel is very close to the endurance strength value, and it has high plasticity under the condition of long-term stretching; the steel has good manufacturability and weldability, but it needs to be preheated to 300 ° C before welding, and the stress needs to be removed after welding deal with.

The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel material 1.8909 products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our material 1.8909 business. We also provide third-party inspection and approval services and inventory management for our customers.

Quenching Improve the hardness of material 1.8909 steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of material 1.8909 steel and comprehensive mechanical properties.

Oxygen (O) is a harmful element in steel such as material 1.8909. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

The company's after-sales service team is a high-quality professional team. Most after-sales employees have rich service experience and have reached the level of after-sales engineer. The after-sales department implements the after-sales personnel responsibility system and a 24-hour response mechanism. The company's advanced customer relationship management system provides customers with "standardized and streamlined services". A sound customer relationship maintenance system, and a "one-stop" customer satisfaction tracking system, all reflect our strong after-sales service guarantee.
