Stainless steel casting

Stainless steel casting

Stainless steel is an iron alloy containing a minimum of 11.5% chromium. Stainless steel's virtues are resistance to corrosion, non-reactivity with either alkaline or acidic foods, and resistance to scratching and denting. Stainless steel's drawback for cooking use is that it is a relatively poor heat conductor. As a result, stainless steel cookware is generally made with a disk of copper or aluminum in or on the base to conduct the heat across the base. Stainless steels, especially precipitating hardening grades, can undergo heat treating to achieve the same mechanical properties as alloy steel while retaining native corrosion resistance. Secondary annealing is also available for applications requiring softer metals.

Stainless steel casting can achieve high levels of corrosion and abrasion resistance without machining or plating, making it one of the most investment casting-friendly metals available. The stainless steel casting process produces very little waste and is often the preferred method for avoiding the high costs of stainless steel.

The specifications can be summarized as follows: available material: stainless steel, carbon steel and refractory steel of various specifications; standard: ASTM, AISI, DIN, JIS etc; application: industrial parts, machinery parts, valve parts, train, craft, doorhandle ,construction and so on; surface treatment: polishing, maching, plating, heat treatment ,etc; products coverage: aircraft manufacturing, ship building, auto, artificial limb, chemical, weapon, sanitary bath equipment and petroleum equipment etc; products: valve, flange, elbow, screw nut, screw bolt, pipe fitting, impeller, coupling, pump parts and so on.
