What is ASTM A420 WPL3 used for?

Grade WPL3 is specified for low-temperature carbon steel pipe fittings used in cryogenic and sub-ambient environments, typically down to −100 °C. It offers impact toughness and strength required for safe service in those conditions.

What are the chemistry & mechanical property limits for WPL3?

Typical maximum composition: C ≤ 0.20%; Mn 0.31–0.64%; Si 0.13–0.37%; P/S ≤ 0.05%; Ni 3.2–3.8%. Mechanical (typical minimums): Tensile 450–620 MPa; Yield ≥240 MPa; Elongation: Longitudinal ≥22%, Transverse ≥14%; impact tested at −100 °C.
