2. ASTM A420 WPL6 low-temperature steel classification.

1, A420WPL6 cryogenic steel is divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, A420WPL6 cryogenic steel heat treatment, water wash, ppc, etc.

2、A420WPL6 low temperature steel can be divided into push, press, forging, mold, etc. according to the production method.

3、A420WPL6 low temperature steel can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.

4, A420WPL6 low-temperature steel by bending radius: can be divided into long-radius elbow and short-radius elbow. (Long radius elbow is the bending radius is equal to 1.5 times the outer diameter of the tube, that is, R = 1.5D Short radius elbow is the bending radius is equal to the outer diameter of the tube, that is, R = 1.0 DD is the diameter of the elbow, R is the radius of curvature).

3, ASTM A420 WPL6 low-temperature steel chemical composition.

C grade Si Mn Nb V P
WPL6 0.30 0.15-0.30 0.60-1.35 0.02 0.05 0.035
S grade CuCrNiMo

V. ASTM A420 WPL6 low-temperature steel applications.

ASTM A420 WPL6 steel is a material in the American Standard, mainly used for low-temperature environment pipe fittings, American Standard valves, flanges and pipe fittings, all using ASTM A420 WPL6 steel material. ASTM A420 WPL6 American Standard low temperature welded or seamless pipe fittings are forged materials, generally used in low temperature environments above -45°C. A333 Gr.6 is used for fittings, and A420 WPL6 is used for pipe fittings. Pipe.

ASTM A420 WPL6 is mainly used for low temperature pressure pipes and pressure vessels. It is a kind of connection fittings used to install in pipes for connection in bends.

ASTM A420 WPL6 cryogenic steel is formed by using a plate of the same material as the pipe, drilling a half-ring elbow with a stamping die, and then assembling and welding the two half-ring elbows. As different types of pipes are welded in different ways, the semi-finished products are usually fixed from the group to the point and the field construction is carried out according to the degree of welding of the pipe.
