SA 387 Grade Plate

ASTM A 387, ASME SA 387, is one of our most popular products. It is a low alloy pressure vessel quality steel for high temperatures. We have a wide range of plate sizes available and thicknesses range from 6 - 100mm. ASME SA387 standard plates are used by the world's leading fabricators who in turn, supply primarily to the oil and petrochemical industry. Applications for ASME SA387 include pressurised vessels, industrial boilers, heat exchangers and pipework.

SA 387 Grade Plate

Plates are available under these specifications in several grades each having different nominal Chromium (Cr) and Molybdenum (Mo) contents as follows :

 

Grade Nominal Cr Content (%) Nominal Mo Content (%)
2 0.5 0.5
12 1 0.5
11 1.25 0.5

Chrome Moly Steel Plates

Chrome Moly Steel Plates is manufactured using chromium and molybdenum elements. Chome Moly steel plate, formally known as Chrome Molybdenum, is usually sold as ASTM A387 or ASME SA387. A387 is alloy steel plate that is designed for use in pressure vessels, process vessels and boilers operating at high temperatures.

The Chrome Moly Steel Plates are highly effective in Salt Water applications.
