Stainless Steel Investment Cast Parts

Stainless Steel Investment Cast Parts

Material: Austenitic Stainless Steel
Process: Lost Wax Investment Casting + CNC Machining
Weight: 2.52 kg
Heat Treatment: Solid Solution
Application: Joint Connector

Austenitic stainless steel should be solid-solution treated before use, so as to maximize the solid solution of various precipitates such as carbides in the steel into the austenite matrix, while also homogenizing the structure and eliminating stress.

Description

OEM Custom Stainless Steel Investment Casting Parts from China Lost Wax Casting Foundry.

Austenitic stainless steel refers to stainless steel with an austenitic structure at room temperature. Austenitic stainless steel is one of the five classes of stainless steel by crystalline structure (along with ferritic, martensitic, duplex and precipitation hardened). In some areas, the austentite stainless steel is also called the 300 series stainless steel. When the steel contains about 18% Cr, 8%-25% Ni, and about 0.1% C, it has a stable austenite structure. Austenitic chromium-nickel stainless steel includes the famous 18Cr-8Ni steel and the high Cr-Ni series steel developed by adding Cr and Ni content and adding Mo, Cu, Si, Nb, Ti and other elements on this basis. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but its strength is low, and it is impossible to strengthen it through phase transformation. It can only be strengthened by cold working. If elements such as S, Ca, Se, Te are added, it has good properties of machinability.

Austenitic stainless steel can also produce castings. In order to improve the fluidity of molten steel and improve casting performance, the alloy composition of cast steel should be adjusted by increasing the silicon content, enlarging the range of chromium and nickel content, and increasing the upper limit of the impurity element sulfur. Austenitic stainless steel should be solid-solution treated before use, so as to maximize the solid solution of various precipitates such as carbides in the steel into the austenite matrix, while also homogenizing the structure and eliminating stress, so as to ensure excellent Corrosion resistance and mechanical properties.
