Guangdong stainless steel casting:

Guangdong stainless steel casting is a general term for iron-based alloys used to produce castings that do not undergo eutectic transformation during the solidification process. A kind of casting alloy. Cast steel is divided into cast carbon steel, cast low alloy steel and cast special steel.

Classification:

① Cast carbon steel. Guangdong stainless steel casting is a cast steel with carbon as the main alloying element and a small amount of other elements. Casting low-carbon steels with a carbon content of less than 0.2%, cast medium-carbon steels with a carbon content of 0.2% to 0.5%, and cast high-carbon steels with a carbon content of more than 0.5%. As the carbon content increases, the strength and hardness of cast carbon steel increase. The cast carbon steel for coffee machine parts has high strength, plasticity and toughness, and low cost. It is used in heavy machinery to manufacture parts that bear heavy loads, such as rolling mill racks, hydraulic press bases, etc.; used in manufacturing on railway vehicles Parts that are subject to large forces and impact, such as bolsters, side frames, wheels, and couplers.

②Coffee machine parts are cast low-alloy steel. Cast steel containing alloying elements such as manganese, chromium and copper. The total amount of alloying elements is generally less than 5%, with greater impact toughness, and better mechanical properties can be obtained through heat treatment. Casting low-alloy steel has better performance than carbon steel, which can reduce the quality of parts and increase the service life.

③ Casting special steel. Robot stainless steel parts are made of alloy cast steel to meet special needs. There are many varieties, usually containing one or more high amount of alloying elements to obtain a certain special performance. For example, high manganese steel containing 11% to 14% manganese is resistant to impact wear and is mostly used for wear-resistant parts of mining machinery and robot stainless steel fittings and construction machinery; various stainless steels with chromium or chromium-nickel as the main alloy elements are used in Corrosion or parts that work under high temperature conditions above 650℃, such as chemical valve bodies, pumps, containers, or steam turbine shells in large-capacity power stations.
