ASTM A420 WPL6 Low Temperature Steel Plate

ASTM A420 WPL6 is an American Standard for Low Temperature Forged Carbon Steel for Seamless Welded Structural Pipe Fittings.

Executive standard: ASME SA-420/SA-420M ASTM A-420/A-420M

A420 WPL6 American standard low temperature seamless or welded pipe fittings, the corresponding pipe material is A333 Gr.6, generally used in low temperature -45 degrees environment, domestically, 16Mn pipe is generally used instead.
