SA387Gr91 steel plate is a chromium-molybdenum alloy steel plate for pressure vessels. SA387Gr91 steel plate is generally used in large nuclear power plants, and of course it can also be used in other places.
SA387GR91 chromium-molybdenum alloy steel has the ability to prevent hydrogen embrittlement, hydrogen corrosion, hydrogen stripping and sulfide corrosion in a medium temperature (350-480 ° C) hydrogen environment.
SA387Gr91 steel plate also has good low temper brittleness. SA387Gr91 steel plate is widely used in the manufacture of fertilizer, petrochemical and thermal power plant equipment, such as ammonia synthesis reactor, coal gasifier, shift furnace and hydrogenation reactor.
The heat treatment of SA387 steel plate can be normalized plus tempered or normalized plus rapid cooling plus tempered.
The main application of SA387Gr91 steel plate
Widely used in petroleum, chemical industry, power station, boiler and other industries, for the production of 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 volute and other equipment and components.
