Alloy Steel Precision Casting

 Alloy Steel Precision Casting contains specified amounts of chromium, nickel or molybdenum to the carbon to enhance harden-ability and toughness. Alloy Steel Casting is most commonly used for components in the oil and gas, and pump and valve industries, but are also suitable for military vehicles and earth-moving and construction equipment. Common elements added carbon steels are Nickel (Ni), Chromium (Cr) and Molybdenum (Mo). Nickel is added to resist corrosion and provide strength, stability and toughness. Chromium is added to resist wear and corrosion and help the steel to increase strength and harden-ability. Molybdenum is added to withstand temperatures and elevate the strength and harden-ability of the steel.  Cast Alloy Steel is precise, complex, and close to the final shape of the parts, which can be used without processing or with little processing, so It is an advanced technology.  In wax pattern process, we mix stearic acid and paraffin wax in wax pattern making,as you know, it is better than polyethylene, and the wax deformation is small.     In shell making, we adopt automatic sand-covering production line, which was invented under the guidance of our general manager. The indoor temperature was controlled by air-conditions, keeping the temperature at  24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.  In shell hardening process, we use aluminiumwww.junlongcasting.com
