For steel parts with higher strength, ductility and toughness requirements, stainless steel casting is required. Cast iron after cast iron production, accounting for about 15% of the total output of castings. It plays an important role in China's heavy industry. The classification of stainless steel casting parts, stainless steel casting processing also has different classifications, the difference is huge, the following are the more common simple classification

1, alloy stainless steel casting processing

According to the total amount of alloying elements, alloy stainless steel casting processing can be divided into two types of low alloy steel and high alloy steel.

1) Low-alloy stainless steel casting processing, China mainly uses manganese, manganese, chromium and so on. Such as ZG40Mn, ZG30MnSi1, ZG30Cr1MnSi1 and so on. Used to make components such as gears, hydraulic cylinders and turbine rotors, and the ZG40Cr1 is commonly used to make important parts such as high-strength gears and high-strength shafts.

2) High-alloy stainless steel casting processing, with wear resistance, heat resistance or corrosion resistance. Such as high manganese steel ZGMn13, is a wear-resistant steel, mainly used in the manufacture of parts under dry friction working conditions, such as excavators grab the front wall and grazing teeth, tractors and water tanks; chrome-nickel stainless steel ZG1Cr18Ni9 and chrome stainless steel ZG1Cr13 And ZGCr28, nitric acid is very resistant to corrosion and is mainly used in the manufacture of parts for chemical, petroleum, chemical fiber and food equipment.

Classification of stainless steel casting parts

2, carbon stainless steel casting processing

In general, low carbon steel ZG15 has high melting point and poor casting properties. It is only used to manufacture motor parts or carburized parts. Medium carbon steel ZG25~ZG45 has higher comprehensive properties than various cast irons, namely high strength, excellent plasticity and Resilience, therefore suitable for the manufacture of parts with complex shapes, high strength and toughness requirements, such as train wheels, forging hammers and anvils, rollers and high pressure valves, carbon steel is the most widely used category; high carbon steel ZG55 low melting point, casting Performance is superior to carbon steel, but its plasticity and toughness are poor, only used to manufacture a small number of wear parts
