Heat -resistant steel, alloy steel with high strength and good chemical stability at high temperature.It includes two categories: antioxidant steel (or high temperature can not support skin steel) and heat -strong steel.Antioxidant steel generally requires good chemical stability, but the load is low.Thermal steel requires higher high temperature intensity and corresponding antioxidants.
Heat -resistant steel welding
Since heat -resistant steel has so many excellent quality, its production technology is naturally much more complicated than other types of steel. Among them, welding is an important link.Generally, heat -resistant steel needs to be treated with quality adjustment when welding, so that it can stabilize the tissue inside the steel, especially for martensite heat -resistant steel, it will also get good comprehensive mechanical properties and high temperature.strength.The iron body steel cannot be strengthened by thermal treatment. It must also achieve a certain internal stress through the welding process. Before welding, annealing is performed.All types of the above types need to be welded in the casting state to better achieve thermal deformation.

Heat -resistant steel component
1. Carbon, when the carbon content is greater than or equal to 0.04%, it is recommended to take two decimal numbers; when the carbon content is not more than 0.030%, it is recommended to take 3 decimal numbers.2. In addition to the CR-NI-Mn steel brand, manganese are recommended to use 2.00%and 1.00%(maximum value) for other types of steel.3. Phosphorus, unless due to technical reasons, the recommended phosphorus content of Austrian steel steel is not more than 0.045%, and other types of steel brand phosphorus content is not greater than 0.040%, but it does not include easy cutting steel brand numberEssence4. Sulfur, due to special technical reasons, requires lower limit values, the recommended sulfur content of various types of steel brands is not more than 0.030%.5. There are also silicon, chromium, nickel, molybdenum, nitrogen, copper, crickets, and 钽.
