Factory directly Steel Precision Casting Supplier - Alloy Steel Gear by Investment Casting and CNC Machining – RMC Foundry Detail:

China OEM custom alloy steel castings by lost wax investment casting process. Carbon steel, low alloy steel, and tool steel castings are used in several industrial applications and customized gears. With their numerous grades, steel and their alloys can be heat-treated to improve its yield and tensile strength; and, adjust hardness or ductility to the engineer’s application needs or desired mechanical properties.

Wear-resistant alloy steel investment castings are the casting parts produced by lost wax investment casting process made of wear-resistant alloy steel. At RMC Foundry, the main sand casting processes we could use for wear-resistant alloy steel are green sand casting, resin coated sand casting, no-bake sand mold casting, lost foam casting, vacuum casting and investment casting. The heat treatment, surface treatment and CNC machining are also available at our factory as per your drawings and requirements.

Among a wide variety of casting alloys, wear-resistant cast steel is a very widely used alloy steel. Wear-resistant cast steel mainly improves the wear resistance of steel castings by adding different content of alloying elements, such as manganese, chromium, carbon, etc., to the alloy. At the same time, the wear resistance of wear-resistant steel castings also depends on the heat treatment method used by the foundry and the structure of the casting.

According to different wear characteristics, the wear of steel castings can be divided into abrasive wear, adhesive wear, fatigue wear, corrosion wear and fretting wear. Wear-resistant steel castings are mainly used in industrial fields with complex working conditions and high mechanical performance requirements, such as mining, metallurgy, construction, power, petrochemical, water conservancy, agriculture and transportation industries. Wear-resistant steel castings are mostly used in abrasion conditions with a certain impact load, such as grinding equipment, excavators, crushers, tractors, etc.
