A387 Gr91 CL2 steel plate production process

A387 Gr91 steel is a chromium-molybdenum alloy steel from ASME SA-387/SA-387M-2017 standard. It is steel used in large nuclear power plants, and it is generally used in other places.
A387 Gr91 CL2 steel plate executive standard: ASME SA-387/SA-387M-2017.
A387 Gr91 CL2 steel plate delivery status: normalizing + tempering

A387 Gr91 CL2 steel plate production process:
Raw materials (scrap steel, pig iron and molten iron) → electric furnace (100 tons electric arc furnace smelting) → converter → LF furnace molten steel refining treatment → VD or VOD furnace molten steel vacuum treatment → die casting (various key die casting lines) or continuous casting (large Slab caster) (50 tons of slab electroslag furnace for remelting a steel ingot) → heating (continuous furnace and soaking furnace) → steel plate rolling (4100 and 4200mm rolling mills) → steel plate heat treatment (normalizing and tempering) Quality) →Steel plate cutting inspection→Inspection

Specific application of A387 Gr91 CL2 steel plate:
Steel can be used as high-temperature superheater and reheater steel pipes for subcritical and supercritical boilers with wall temperature ≤ 625, as well as high-temperature headers and steam pipes with wall temperature ≤ 600, as well as nuclear power heat exchangers and furnace tubes for petroleum cracking equipment.
