China wear resistant alloy steel casting products with OEM custom and CNC machining services

Wear-resistant alloy steel sand castings are the casting parts produced by sand casting process made of wear-resistant alloy steel. At OBT 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.

Steel castings are classified according to their chemical composition and are divided into cast carbon steel parts and cast alloy steel parts. According to the classification of use characteristics, steel castings can be divided into engineering and structural cast steel (carbon alloy steel and alloy structural steel), cast special steel parts (corrosion-resistant stainless steel, heat-resistant steel, wear-resistant steel, nickel-based alloy ) and casting tool steel (tool steel, die steel). In the foundry industry, the materials used for steel castings are generally subdivided as follows:
1) Cast Carbon Steel: cast low carbon steel, cast medium carbon steel, cast high carbon steel (high strength carbon steel)
2) Medium-alloy Steel and Low-alloy Steel for Casting: cast manganese steel, cast silico-manganese steel, cast manganese-molybdenum steel, cast manganese-molybdenum-vanadium copper steel, cast chromium steel, chromium-molybdenum cast steel, chromium-manganese-silicon cast steel, chromium-manganese Molybdenum cast steel, chromium molybdenum vanadium cast steel, chromium copper cast steel, molybdenum cast steel, chromium nickel molybdenum cast steel, etc. Different chemical elements can play a different role in improving the corresponding performance. In the following articles, we will introduce the properties of related alloy steels and the roles played by chemical elements one by one.
3) Corrosion-resistant Stainless Steel: ferritic stainless steel, martensitic stainless steel, austenitic stainless steel and austenitic-ferritic duplex stainless steel.
4) Heat-resistant Steel: high chromium steel, high chromium nickel steel and high nickel chromium steel.
5) Wear-resistant Cast Steel: wear-resistant manganese steel, wear-resistant chromium steel
6) Casting Special Steel and Professional Steel: low-temperature cast steel, foundry tool steel (die steel), pressure cast steel, precision casting steel, centrifugal cast cast steel pipe.

Green sand is a kind of moulding sand with no need to dry and takes the bentonite as binder. The basic feature of green sand is that it does not need to be dried and solidified, while it has a certain wet strength. Although the strength is low, it has better retreatability and is easy to shake off; moreover, the green sand casting process has several advantages of high moulding efficiency, short production cycle, low material cost and it is easy to organize flow production. However, because the sand mold is not dried, moisture vaporization and migration appear on the surface of the sand mold during casting, which makes the casting prone to have blowholes, sand inclusions, bulging sand, sticky sand and other casting defects.


In order to give full play to the advantages of green sand molding and improve the quality of castings, it is necessary to maintain stable molding sand performance, compact and uniform sand molds and reasonable casting process during the production process. Therefore, the development of green sand molding technology has always been closely linked to the development of molding machine and molding technology. Recently, green sand mechanized moulding has developed from ordinary machine moulding to high-density machine moulding. The productivity of moulding, the compactness of sand molds, and the dimensional accuracy of castings continue to increase, while the surface roughness value of castings continues to decrease.
