Quality stainless steel elbow is a kind of pipe fittings, and also a kind of pipe fittings that change direction in engineering pipelines. The forming process of stainless steel elbow: cold working stainless steel, nickel and copper to form a mandrel. The carbon steel is heated and forms the inner mandrel. The quality stainless steel elbow is usually used in construction machinery. The elbow has a large diameter and is smooth and beautiful.

Distinguish the quality of quality stainless steel elbow:
1. Appearance quality, rust-free, high surface finish, defect-free stainless steel is produced in a large factory, and its performance is relatively good.
2. Preliminary judgement, usually non-magnetic stainless steel (austenite) has better corrosion resistance than magnetic stainless steel (ferrite).
3. The chemical composition of stainless steel with high nickel content and low carbon content usually has good corrosion resistance, but the price is relatively expensive.

The commonly used processing methods of quality stainless steel elbow are casting, welding after partial pressure forming and welding after slitting. It may be difficult to manufacture large stainless steel elbows using the above method. Due to the casting method, it is difficult to manufacture cores, and it is difficult to find large-scale turning and milling equipment for cutting and cutting. The equipment and processing technology are limited, and it is difficult to manufacture such a large mold by the pressing method, which is expensive and has a long manufacturing cycle.
