Introduction of heat resistant steel casting

Through smelting, purification and ratio of heat resistant steel castings at high temperature has higher strength and good chemical stability. It includes oxidation - resistant steel (or high - temperature steel) and hot - strength steel. Oxidation resistant steels generally require good chemical stability, but bear lower loads. Hot strength steels require high temperature strength and oxidation resistance.

Through smelting, purification and ratio of heat resistant steel castings at high temperature has higher strength and good chemical stability. It includes oxidation - resistant steel (or high - temperature steel) and hot - strength steel. Oxidation resistant steels generally require good chemical stability, but bear lower loads. Hot strength steels require high temperature strength and oxidation resistance. Heat resistant steel castings are commonly used in the manufacture of boilers, steam turbines, power machinery, industrial furnaces and aviation, petrochemical and other industrial sectors working at high temperatures parts. These parts require not only high temperature strength and resistance to high temperature oxidation corrosion, but also enough toughness, good machinability and weldability, and certain structure stability according to different USES. Heat resistant steel and rust resistant steel in the use of the scope of the cross, some stainless steel has heat resistant steel characteristics, both can be used as rust resistant steel, can also be used as heat resistant steel. Industrial USES is very wide, so the heat resistant steel castings heat-resistant steel, the highest temperature at 1300 ℃, some factories use condition is very bad, we can according to customer requirements drawing material processing production, can also according to the requirements of the customers with casting work environment, etc. Choose the appropriate material of castings, let customers reduce costs, using casting longer life.
