casting Material technology, such as ductile iron, carbon steel, gray iron, stainless steel, malleable iron and alloy.
Stainless Steel include austenitic stainless steel martensitic stainless steel and ferric stainless steel. this material is suitalbe to sand casting and investment casting method. Austenitic steels have austenite as their primary phase
Grey Cast Iron (Gray iron) HT200, HT250, HT300, HT350 in Chinese Standard GB/T 9439
Carbon steel have a good content of carbon, so it is easy to casting. especially A216 WCB. It is important to clarify the meaning of carbon steel in the generic sense and in the more narrow context used in this report. The term steel is usually taken to mean an iron-based alloy containing carbon in […]
Duplex Stainless steel has two phase micro-structure consisting of grains of Ferritic and Austenitic stainless steel. It is mainly used in pump fittings and oil field. Casting Quality Industrial can produce SAF2205 DUPLEX STAINLESS STEEL castings.
Cast Iron is individed to four types: gray iron, ductile iron, malleable iron, vermicular cast iron, abrasion-resistant cast iron and corrosion resistant cast iron. Generally, we mainly use sand casting method to make iron castings, such as green sand casting, resin sand casting, Sodium silicate sand casting , lost foam casting and centrifugal casting. Gray […]
Duplex stainless steel castings, sorted by standard. Duplex Stainless steel has two phase microstructure consisting of grains of Ferritic and Austenitic stainless steel. It has a better strength and corrosion resistance property than stainless steel 304/316. Duplex stainless steels have lower nickel and molybdenum contents than their austenitic counterparts of similar corrosion resistance.
The Engineering and physical properties of cast iron wary with the type of iron; the designer must match the engineering requirements with al the properties of the specific type of cast iron being consiered. Machinability, e.g., is significantly affected by the type of cast iron specified. Gray cast iron is the most machinalbe; the white […]
Cast iron is classified in to fire basic types: each type is generally based on graphite morphology as following:Gray Iron
Ductile Iron
Malleable Iron
Compacted Graphite Iron
White Iron
The Ideal of cast iron with ductility, long sought by metallurgists, was realized with the introduction of ductile iron in 1948. Acclaimed to be one of the most significant metallurgical developments in this century, ductile iron has had an increasing impact in many industries. Ductile iron has ductility – as the name implies – and […]
Malleable Iron in EN 5922, ISO 5922, DIN 1692, ASTM A197
Ductile iron, also called ductile cast iron, spheroidal graphite iron, or nodular cast iron. While most varieties of cast iron are brittle, ductile iron is much more flexible and elastic, due to its nodular graphite inclusions.
From the carbon content of material, we can divide iron and steel. Cast irons typically contain 2-4 wt% of carbon with a high silicon concentrations and a greater concentration of impurities than steels. Iron (Fe) is not a high-purity metal commercially but contains other chemical elements which have a large effect on its physical and […]
Fasteners are manufactured in a wide range of materials from common steel to titanium, plastic and other exotic materials. Many materials are further separated into different grades to describe specific alloy mixtures, hardening processes, etc. In addition, some materials are available with a variety of coatings or plating to enhance the corrosion resistance, or appearance […]
