As a quality chrome moly steel, A387 Grade 12 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).
The higher levels of chromium also provide excellent corrosion and oxidation resistance.
