The ASTM A387 specification is the Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum intended primarily for use in welded boilers and pressure vessels designed for elevated temperature service. SSAB can supply A387 Grade 22 to the tension test requirements for Class 1 and/or Class 2.
Width: Inquire for widths and lengths outside the noted ranges.
Tensile testing is performed in the transverse direction.
1) Refer to ASTM A20/A20M for Elongation adjustments based on plate thickness.
