stainless tube elbows suppliers - GK

The difference between stainless steel elbow and carbon steel elbow is mainly the material. The chemical composition contained in the stainless steel street elbow will keep the surface of the elbow from rusting and corrosion for a long time.

In piping systems, elbows are fittings that change the direction of the piping. According to the angle, stainless elbow fittings have 45 ° and 90 ° and 180 ° most commonly used. In addition, according to the needs of the project, besides above three angles, stainless tube elbows also include other abnormal elbows such as 60 °.

While, according to the production process, stainless steel duct elbow can be divided into welding elbow, stamping elbow, hot pressing elbow, push elbow, casting elbow, forging elbow, clip elbow, etc.

Stainless steel is usually made by adding a high proportion of Cr, Ni and other alloys on the basis of carbon steel, and the content ratio can reach more than 20%. Common steel types are: 304, 304L, 321, 316, 316L, 1Cr18Ni9Ti, 0cr18ni9. GK stainless steel elbows are produced with these materials.
