Stainless steel castings Stainless steel has the characteristics of non-rust, corrosion resistance and bright appearance, so it has been the molding material for various metal products. Stainless steel casting, as the name implies, is the casting process of stainless steel alloy. Investment casting or lost wax casting, is the most precise casting method for manufacturing stainless steel products, especially those with irregular or complex structures, so  stainless steel investment casting is almost equivalent to stainless steel precision casting . The whole casting stainless steel process contains several steps: mold making, wax mold making, tree assembly, dipping and dewaxing, pouring, etc.   304 An austenitic stainless steel with Ni content greater than 8%, a food grade alloy that can be used for casting domestic and commercial stainless steel parts. It is the most widely used stainless steel casting material.  304 stainless steel castings can be used in environments where air is les

  Ductile Iron Valve Plate   1. The Selection Principle of Carbon in Ductile Iron   Carbon is the basic element of nodular cast iron, and high carbon contributes to graphitization. Since the influence of graphite on mechanical properties has been minimized after the graphite is spherical, the carbon content of ductile iron is generally higher, between 3.5% and 3.9%. Too high carbon content will cause graphite to float. Therefore, the upper limit of carbon equivalent in ductile iron is based on the principle that no graphite floats occur.   2. Selection Principle of Silicon in Ductile Iron   Silicon is a strong graphitizing element. In spheroidal graphite cast iron, silicon can not only effectively reduce the white mouth tendency and increase the amount of ferrite, but also has the function of refining the eutectic cluster and improving the roundness of graphite spheres. Silicon increases the ductile-brittle transition temperature of cast iron and reduces the impact toughness. Therefore

As a   ductile iron supplier , I will share it you. The chemical composition of ductile iron mainly includes five common elements: carbon, silicon, manganese, sulfur, and phosphorus. For some castings with special requirements for structure and performance, a small amount of alloying elements are also included. Different from ordinary gray cast iron, in order to ensure graphite spheroidization, nodular cast iron must contain trace residual spheroidizing elements. Ductile Iron Valve Plate   1.
