How to reduce delamination of welding хардокс 450 steel

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in welding хардокс 450 steel etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.

According to the market forecast released by Eurofer on August 5, the output of all welding хардокс 450 steel steel consumption industries in the European Union will drop by 12.8% in 2020, and rise by 8.9% in 2021. However, the European Union said that the government's "awesome strength" support will reduce the welding хардокс 450 steel steel consumption intensity in the construction industry significantly less than other industries.

Hot-rolled coil is a commonly used steel product in the industry. It has a relatively wide variety of products and a wide range of uses. welding хардокс 450 steel, Hot-rolled coils are widely used in related industries such as petrochemical equipment, automobiles and bridges. Hot-rolled coils are also used in machinery industries such as ships and automobiles because of their good toughness and relatively high strength.
