Stainless steel elbow is different from carbon steel elbow is mainly different material, its chemical composition will keep the surface of the elbow for a long time will not rust, will not be corroded. According to the standard production can be changed into:
1. According to the manufacturing standard, it can be divided into GB standard, ship standard, electrical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
2. According to the production method, it can be divided into pushing, pressing, forging, casting, etc.
The 90° stainless steel elbow is mainly used for connecting pipe fittings in pipeline installation, and is used for connecting pipe corners. Connect two pipes of the same or different nominal diameters to make a 90° turn.
Stainless steel elbow is usually on the basis of carbon steel with a high proportion of Cr, Ni and other alloys, content proportion can reach more than 20%. Common steel types are: 304,304 L, 321,316,316 L, 1Cr18Ni9Ti,0cr18ni9, the first number of steel numbers for Japan, the United States steel number method, the last one (1Cr18Ni9Ti) for the domestic steel number method.
Stainless steel characteristics: strength, toughness indicators are up to standard, its outstanding advantage is corrosion resistance, in chemical papermaking and other corrosive occasions must use stainless steel, of course, the cost is also higher!
