SA-387 execution standard: SA-387/SA-387M (exactly the same as ASTM standard A387/A387M-11).
SA-387 chromium molybdenum alloy steel plates in the middle temperature (350 ~ 480 DEG C) hydrogen environment can prevent hydrogen embrittlement and hydrogen corrosion, hydrogen sulfide stripping, corrosion resistance, and has low temper brittleness of good manufacturing, widely used in chemical fertilizer, petroleum chemical and thermal power plant equipment, such as ammonia synthesis reactor, coal gasification furnace and transform furnace and hydrogenation reactor.
SA-387 smelting method: 18236663769
With special smelting methods, the content of phosphorus can be reduced, resulting in high brittleness to SA387 and good impact toughness at low temperature.
The SA387 material is suitable for the hydrogenation reaction at high temperature and the refining and gas treatment in the conversion equipment. The maximum thickness of the steel plate can reach the thickness of 250mm. According to the requirements of different thickness and impact, the heat treatment of SA387 steel plate is treated with normalizing and tempering or normalizing with rapid cooling and tempering.
SA-387 order requirement: 18236663769
1. the steel plate supplied according to this standard shall meet the requirements of the A20/A 20M standard. These requirements include test and re examination methods and procedures, allowable deviations of size and weight, repair of quality and defects, marking and loading and ordering information.
2. in addition to the basic requirements specified in this standard, a number of additional requirements may be used when more control, test or inspection is required to meet the requirements of the final use. The purchaser shall consult the additional requirements listed in this standard and the detailed requirements in the A 20/A 20M standard.
3. if the requirements in this standard are not consistent with the requirements in the A 20/A 20M standard, the requirements in this standard are subject to the requirements.
Manufacturing: steelmaking operating steel should be a sedative steel.
SA-387 heat treatment: 18236663769
All steel plates shall be heat-treated except for grade 91 steel. The heat treatment method is annealing, normalizing and tempering. When the purchaser agrees, the austenitizing temperature is accelerated by cooling by blast or liquid quenching. Then the temper was carried out. The lowest tempering temperature is as follows:
Class temperature, ()
2,12,11
1150 (620)
22,22L, 21,21L, 9
1250 (675)
Five
1300 (705)
The 91 stage steel plate should be tempered at 19001975 (10401080) and under no less than 13501470 (730800).
The 2. level 5, 9, 21, 21L, 22/22L and 91 order steel plates shall be delivered at the stress relieving or annealing state when the heat treatment is not specified according to 1 requirements.
3. unspecified order steel plate for heat treatment under the requirements of 1, shall be carried out by the purchaser at the request of 1 and the applicable Table 1 or table 2 when the heat treatment is required.
