ASTM A387 Gr.22 Alloy Steel Plate for Pressure Vessel Alloy K21590 Steel Plate Thickness 6.0 - 40.0mm
ASTM A387 Gr.22 Alloy Steel Plate for Pressure Vessel Alloy K21590 Steel Plate Thickness 6.0 - 40.0mm
ASME SA387-22 steel plate is a pressure vessel grade steel specially designed for use in elevated temperature service and applications in which sour gas is present.
WHAT ARE THE BENEFITS OF SA 387 GRADE 22 STEEL PLATE?
Sometimes called a chrome-moly plate, higher levels of chromium provide excellent corrosion and oxidation resistance. Additional characteristics of SA387 grade 22 plate, which is also referred to as ASTM A387-22 steel plate, include:
- Superior temperature resistance
- Improved tensile strength
- Heightened rust protection
Thicknesses Range of our SA387 Gr.22 Alloy Steel Plate
As a leading SA 387 Grade 22 steel plate supplier, Universal Steel America stocks SA387-22 steel plate with thicknesses from 6 - 40mm in the normalized and quench-and-tempered conditions.
Width and Length
Width and length restrictions exist, depending on plate weight and mill capabilities. Average widths are 96 and 120 inches, whereas typical lengths are 240 and 480 inches. Specialized testing and chemical or physical requirements can vary, depending on the final application requirements.
