A387Gr.11 heat resistant steel pressure vessels and pipes.

A387Gr.11 heat resistant steel pressure vessels and pipes.

A387Gr11 boiler steel pipe is under steel specification standard ASTM A387 for pressure vessel steel pipe, alloy steel with Chromium-molybdenum. A387Gr11 intended primarily for welded boiler and pressure vessel&tanks.
With the advantages of Cr Mo steel, carbon steel is heat resistant strength is slightly higher, but manufacturing is more complex, need whole heat treatment.

Cr Mo steels with higher strength, heat resistance, good corrosion resistance, although manufacturing also has a certain degree of difficulty, the need for heat treatment, but the overall performance is good, the price is cheap.
Mechanical property for A387Gr11 steel: Yield strength: 240MPa, tensile strength: 415-585(MPa), elongation (%): under 200mm, 19. Under 50mm, 22.
