Carbon Steel Casting

Carbon steel is one of the main materials in the current carbon steel investment casting industry. It has the advantages of low cost, high wear resistance, easy preparation, and can be heat treated to improve its strength, ductility, and processability.

Classification of carbon steel

Low carbon steel (<0.20% C):

Because of its low strength, low hardness, and softness, it is also called soft steel.

Medium carbon steel (0.20 to 0.50% C):

It is the most widely used material in various uses at medium strength levels. In addition to being used as a building material, it is also widely used in the manufacture of various mechanical parts.

High carbon steel (> 0.50% C):

After being properly heat-treated or hardened by cold drawing, high carbon steel has the advantages of high strength, high hardness, high elasticity, and not easy to deform.

Advantages of Carbon Steel Casting

  • Compared with other steels, carbon steel uses the largest amount and is easily obtained by investment casting technology.

  • Carbon steel can obtain higher hardness and better wear resistance after heat treatment.

  • The hardness in the annealed state is very moderate, and it also has good mechanical.

  • The raw materials of carbon steel are very common, easy to obtain, and the cost of production is relatively low.

Alloy Steel Casting

Alloy Steel Casting

Alloy Steel Casting

Alloy steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements to ordinary carbon steel. According to the different added elements, and adopt appropriate processing technology, can obtain high strength, high toughness, wear resistance, corrosion resistance, low-temperature resistance, high-temperature resistance, non-magnetic and other special properties.

Advantages of Alloy Steel Casting

  • Different alloys will have different properties.

  • Common improvements include corrosion resistance, oxidation resistance and improved heat resistance. For example, molybdenum can increase material strength; nickel increases toughness; chromium can increase temperature strength, hardness and corrosion resistance.

  • Alloy steel has good wear resistance and corrosion resistance, and strength performance is very high. Therefore, it can be used in the fields of engineering machinery and equipment, loading and unloading machinery, mining machinery and equipment, metallurgical machinery and equipment, construction machinery and equipment.
