SA387 Gr12 CL2 steel is equivalent to 15CrMoR plate

SA387 Gr12 CL2 steel plate delivery status (heat treatment): normalizing+tempering (NT)

SA387 Gr12 CL2 steel plate classification: boiler and pressure vessel steel plate.

The technical conditions recommend:
Max. PWHT: 690 ± 14℃ x 20 h,
Min. PWHT: 690 ± 14℃ x 6 h

When the thickness of the steel plate is ≤ 30mm, the full-thickness sample shall be used for the test. When the thickness is>30mm, the full-thickness sample or sampling at 1/4 of the plate thickness can be used for the test.

The notch of the impact energy sample is on the side of the sample, and its axis shall be perpendicular to the rolling surface of the steel plate. Electric furnace steelmaking - LF furnace refining - VD furnace vacuum degassing - plate rolling - flaw detection - normalizing - tempering - steel plate finishing - performance inspection.

Use of SA387 Gr12 CL2 steel: SA387 Gr12 steel is equivalent to 15CrMoR, and is used in petroleum, chemical, power station, boiler and other professions, and is used to manufacture reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum cylinders, high-pressure water pipes of hydropower stations, turbine volutes and other equipment and components.
