ASTM/ASME A387 11 Class 2 steel chemical composition
ASTM/ASME A387 11 Class 2 is available from stock in a range of thicknesses from 6 mm to 60 mm.A387 Grade 11 Class 2 is used in a variety of industries and is highly effective, particularly in the oil, gas and chemical industry, where liquids and gases are often stored at high temperature (see pressure vessels).
We supply high quality ASME SA387 Gr 11 Class 2 and ASTM A387 Gr11 Class 2 chrome moly pressure vessel steel plates from various origin such as China. A387-11-2 and SA387-11-2 are killed and thermally treated as requested by ASTM A387 and ASME SA387, both SA387 and A387 are described as "Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum". The specification covers alloy steel plates intended primarily for welded boilers and pressure vessels designed for elevated temperature use, due to it’s 1.25% chromium, 0.5% molybdenum and effective working temperature up to 575°C, this steel grade has been widely used in the variety of industries and is significantly superb particularly in oil and gas, petrochemical and power plant where high temperatures is a must for the industries.
