ASME SA387 Gr 11 Class 2 and ASTM A387 Gr11 Class 2 Chrome Molybdenum steel plates

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 Korea, Japan, China, Eastern European, Western European and Epididymitis USA. 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. The high level of chromium provides excellent corrosion and carbohealth.com oxidation resistance, compelling in sour gas applications

A387 and SA387 Excellent Corrosion and Oxidation Resistance

The Molybdenum component in the SA387 alloy, as well as the tensile strength at high temperatures, provide high resistance against oxidation and corrosion by increasing the good news i saw a dog today lattice strain of the steel structure. This effectively stops the corrosive agents from dissolving the iron out of the steel structure.
