Stainless steel castings refer to some kinds of ferroalloys whose chromium content surpass 11.5% measured by weight, which are not easy to rust.Adding chromium and nickel in steel can make it produce anticorrosive oxide film so as to protect the steel from oxide etch by air, especially the oxygen, certain acid, alkali and water in external environment.

Performance characteristics of stainless steel casting: excellent mechanical and physical properties, overall performance combined with various strength, hardness and toughness, one or more special performance, such as wear resistance, high and low temperature resistance, corrosion resistance, etc.

Lost wax casting is one kind of casting method for manufacturing metal products, which refers to precision casting.Modern precision casting is called investment precision casting. Lost-wax precision casting is generally used for small castings.

Lost wax casting process is as follows:Press liquid paraffin wax into briquetting→ take out wax pattern→ fit gate→ paint and make shell→ melt wax pattern→ bake mold shell→pour molten metal→take out castings →clean pouting gate and burr → test and put it in storage.

Common castings made by lost wax precision castings are numerous, such as lost wax casting steel, one of the advantages the casting is its flexible design, and designers have the greatest freedom of choice the casting shapes and sizes. The metallurgical manufacturing made by the lost wax casting steel has strong adaptability and variability, engineering and high reliability.

Henan Metals & Minerals could use three ways to produce the investment castings / lost wax castings:

1.The sodium silicate process for large- scale parts

2. The silicon sol process for high dimension precision and high finish parts

3.The compound technology are somewhere in between

Referred to the weight of investment castings / lost wax castings, Henan Metals & Minerals can supply from 10 g to 130 kg.We supply the investment castings according to customer's requirments which are made of carbon steel, alloy steel and stainless steel.
