The difference between stainless steel elbow and carbon steel elbow

The main difference between stainless steel elbows and carbon steel elbows is the difference in materials. The chemical composition contained in them will keep the surface of the elbows from rusting and corrosion for a long time. According to standard production, it can be transformed into:

1. According to manufacturing standards, it can be divided into national standard, ship standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.

2. According to the method of production, it can be divided into pushing, pressing, forging, casting, etc.

90 ° stainless steel elbow is mainly used as a kind of connecting pipe fitting in pipeline installation, and is used for connecting the pipe corner. Connect two pipes with the same or different nominal diameter to make a 90 ° turn.

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, the first several steel numbers expressed by numbers are Japan, the US steel number representation method, the last one (1Cr18Ni9Ti) is the domestic steel number representation method.

Stainless steel characteristics: strength and toughness indexes are the best among various steels, and its most prominent advantage is corrosion resistance. Stainless steel must be used in corrosive occasions such as chemical papermaking. Of course, the cost is also high.
