Masteel UK is a leading distributor of high-quality steels worldwide. We have a vast range of steel products available including a range of chromium molybdenum steel plates that are specifically developed for pressure vessels.

This blog post will discuss two specific standards of chrome moly steel that we supply; ASTM A387 and SA387 Grade 12 Class 2.

What is Chromium Molybdenum Steel?

Chromium Molybdenum steel is a type of low alloy steel that is used in a wide range of industries. The chromium provides excellent oxidation and corrosion resistance, and the molybdenum allows the steel to work at higher operating temperatures and gives higher strength.

The anti-corrosive properties, high-temperature resistance, and increased tensile strength make chromium molybdenum highly effective in harsh saltwater environments, as well as in fossil fuel power stations and pressure vessels.

Chromium Molybdenum Steel from Masteel

We supply an extensive selection of chromium molybdenum steel plate, and as we are a major stockholder of these steel plates we can provide global shipping with a very fast turnaround.

Our in-house cutting and profiling service allows us to supply steel plates that are accurate to customer specifications, and we can provide them in a variety of plate widths and thicknesses.

ASTM A387 Grade 12 Class 2 and ASME SA387 Grade 12 Class 2

These standards both cover a high-quality chromium molybdenum steel, which is ideal for use in pressure vessels.

They have a nominal chromium content of 1.00% and a nominal molybdenum content of 0.50%. The tensile strength of these steels is 65-85 ksi with a yield strength of 40 ksi.

Masteel stocks a range of steel plates that are certified to both ASTM A387 Grade 12 Class 2 and ASME SA387 Grade 12 Class 2. The plates are available pre-tested in order to provide immediate shipping, or third-party testing is available on request for more specific testing demands.
