The main difference between the stainless steel elbow and the carbon steel elbow is the material. The chemical composition contained in the stainless steel elbow keeps the elbow surface from rusting for a long time and will not be corroded. According to the standard production can be:
90° stainless steel long radius elbow
1. Division by manufacturing standards can be divided into national standard, ship standard, electric standard, water standard, American standard, German standard, Japanese standard, and Russian standard.
2. The division of manufacturing methods can be divided into pushing, pressing, forging, and casting.
The 90° stainless steel elbow is mainly used as a connection fitting in pipe installations for the connection of pipe bends. Connect two pipes of the same or different nominal diameters to make a 90° turn of the pipe.
Usually on the basis of carbon steel increased by a high proportion of Cr, Ni and other alloys, the proportion of up to 20%. Common steel grades: 304,304L, 321,316,316L, 1Cr18Ni9Ti, 0cr18ni9, several former steel represented numerically as Japan, the United States steel representation method, the last one (1Cr18Ni9Ti) for domestic steel representation method.
Stainless steel properties: strength, toughness index various steels is the best, most prominent advantage is its corrosion resistance, in the case of strong corrosive chemical papermaking stainless steel must be used, of course, cost is high!
