SA387 Gr.22 Class 2 Steel Plate Pressure Vessel Plate Width 1000-2200mm Steel Plates
ASTM A387 Grade 22 (ASME SA387 Grade 22) is Chrom-Moly steel plate used for making boilers and pressure vessles designed for high temperature high pressure serivce, chrome content at 2.00% to 2.50%, and Moly 0.90% to 1.10% for SA387 GRADE 22 material.
The more content of chromium will provide better corrosion and oxidation resistance, ASTM A387 Grade 22 / ASME SA387 Grade 22 material could be used storage oil, gas, or other liquid for industries, and also compatible with sour services.
A20/A20M: General requirements for pressure vessel plates.
A370: Test specification for mechanical properties of steel
A435/A435M: For straight-beam ultrasonic examination of steel
plates
A577/A577M: For ultrasonic angle beam examination of steel plates
A578/A578M: For straight beam UT examination of rolled steel plates
in special applications
A1017/A1017M: Specification for pressure vessle plates of alloy
steel, chromium-molybdenum-tungsten
A5.5/A5.5M: Low alloy steel electrodes for shield metal arc
welding.
A5.23/A5.23M: Low alloy steel electrodes for fulxes for submerged
arc welding.
A5.28/A5.28M: For gas shielded arc welding
A5.29/A5.29M: For flux cored arc welding.
