Short Description:

The heat treatment of steel castings is based on the Fe-Fe3C phase diagram to control the microstructure of the steel castings to achieve the required performance. Heat treatment is one of the important processes in the production of steel castings. The quality and effect of heat treatment are directly related to the final performance of steel castings.

Available grade of duplex stainless steel: 1.4460, 1.4462, 1.4468, 1.4469, 1.4517, 1.4770, A 890 1C, A 890 1A, A 890 3A, A 890 4A, A 890 5A, A 995 1B, A 995 4A, A 995 5A, 2205, 2507, 022Cr22Ni5Mo3N, 022Cr25Ni6Mo2N.

Gray Iron Sand Casting Company from China with OEM Custom and CNC Machining Services.

Cast iron is an iron-carbon cast alloy with other elements that is made by remelting pig iron, scrap, and other additions. For differentiation from steel and cast steel, cast iron is defined as a cast alloy with a carbon content (min 2.03%) that ensures the solidification of the final phase with a eutectic transformation.

Depending on chemical specifications, cast irons can be non- alloyed or alloyed. The range of alloyed irons is much wider, and they contain either higher amounts of common components, such as silicon and manganese, or special additions, such as nickel, chromium, aluminum, molybdenum, tungsten, copper, vana- dium, titanium, plus others. Generally speaking, the cast iron could be divided into gray iron, ducitle iron (nodular iron), white cast iron, compacted graphite iron and malleable cast iron.
