A387 / SA387. A387/SA387 refers to the ASTM / ASME standards respectively. Both ASTM and ASME set international technical standards for the supply of a wide variety of materials including steel. Equivalent standards include BS (British Standard), DIN (German Standard) and EN (Euro Norm). Different varieties of chrome moly are denoted by the Alloy Steel Plates SA387 Grade 11 Class 1 / 2 MIP ASTM A387 Grade 22 Class 2, 2.25% chromium 1% Molybdenum Effective working temperature up to 600°C EXCELLENT CORROSION AND OXIDATION RESISTANCE OF CHROME MOLY STEEL PLATE The Molybdenum component in the SA387 alloy, as well as increasing the tensile strength at high temperatures, also provides high resistance against oxidation and corrosion by increasing the lattice Can I weld ASTM A387 Gr22 and 304 steel plate together?Mar 13, 2021 · Before welding, clean up the oxide layer, oil, moisture, rust, etc. within 200mm of the groove and both sides of the steel plate. The specific welding process parameters are shown in the table. Post-weld stress relief heat treatment; Post-welding stress relief heat treatment is an important process to prevent welding cracks.
An electron beam welding procedure is being developed for welding 8 in. thick SA 387 Grade 22 Class 2 (2/sup 1///sub 4/ Cr--1 Mo) steel. Work is in progress for developing 4/sup 1///sub 2/ inch deep partial penetration electron beam welding procedures. A total of 95 welds has been made to date in the horizontal position.
