1. 4468 duplex stainless steel is a new steel grade of European corrosion resistant cast steel standard EN10283: 1998 and also a new cast duplex stainless steel type of nitrogen-containing austenitic and ferrite, which combines the advantages of ferritic stainless steel and austenite stainless steel. Its coefficient of thermal expansion is lower than that of austenitic stainless steel and it has excellent comprehensive properties in strength, plasticity, impact toughness and corrosion resistance in the cast stainless steel series. Owing to…

Compared with other casting methods or other metal forming processes, stainless steel precision castings general adopt lost wax investment casting. There are several benefits of stainless steel investment casting: Can Improve the Utilization Rate of Materials Investment casting can significantly reduce the machining amount of products and save the consumption of machining time and machining tools. Waste stainless steel materials can be recycled: almost all the casting risers and waste stainless steel castings in the casting workshop are reused, so…

Duplex stainless steel refers to the stainless steel that about half of the solution structure is ferrite phase and the other half is austenite phase and it is generally required that the minimum mass fraction of the less one is 30%. Duplex stainless steel combines the excellent toughness and weldability of austenitic stainless steel with the high strength and chloride stress corrosion resistance of ferritic stainless steel, meanwhile it has good local corrosion resistance and comprehensive mechanical properties. So, duplex stainless steel castings are widely used in petroleum, natural gas, fertilizer,…

Duplex stainless steel refers to a kind of stainless steel grade containing both austenite and ferrite in steel. The volume fraction of two phases in duplex stainless steel which has been widely used in engineering is roughly equal presently. Therefore, it combines the features of austenitic stainless steel and ferritic stainless steel. Compared with ferritic stainless steel and martensitic stainless steel, it has the characteristics of high toughness, low brittle transition temperature and significantly improved intergranular corrosion resistance and weldability. Meanwhile,it retains the the ferritic stainless steel’s characteristics of high…

The faucets in the marketplace are mainly copper materials, but there is lead element in copper alloys, which is harmful to people’s health. Therefore, it is a kind of trend to develop stainless steel faucets. The stainless steel faucet has not been widely used owing to its complicated production process and expensive materials. But now in the kitchen,these utensils are contacted with food directly,such as vegetable basins, pots and spatulas are all made of stainless steel and even a straight drinking fountain is also equipped with stainless steel faucets. Stainless steel faucets can meet the requirements in terms…

Investment casting, also known as lost wax casting, is a production process of near net forming and the most advanced casting process at present.Through investment casting, we can make semi-finished or finished stainless steel castings with complex shapes, high dimensional accuracy, smooth surface and close to the final shape of parts, which can be directly used without machining or after a small amount of machining. Stainless steel investment casting process includes: First make a wax mold with the same size…

About Feed Auger The feed auger is being used in a calf feeder, to convey pallets, palm kernel, magnesium oxide, molasses and magnesium sulphate. The feed auger is normally designed in 304 stainless steel grade and has to be made by lost wax investment casting for its complex shape. Using 304 stainless steel is a smart choice for manufacturing feed auger project and longevity. It is cost-effective in comparison to other materials. Its high quality and durability ensures that feed…
