Stainless steel

It is usually formed 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 grades are: 304, 304L, 321, 316, 316L, 1Cr18Ni9Ti, 0cr18ni9. The first several steel grades represented by numbers are Japanese and American steel grades, and the last one (1Cr18Ni9Ti) is the domestic steel grade representation method.

Characteristics of stainless steel: The strength and toughness index are the best among all kinds of steel. Its most prominent advantage is corrosion resistance. Stainless steel must be used in highly corrosive occasions such as chemical papermaking. Of course, the cost is also high!

Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect with the pipe are: direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, hot pressing elbow, push elbow, casting elbow, forging elbow, clip elbow, etc. Other names: 90° elbow, right-angle elbow, love and bend, white steel elbow, etc.
