ASME SA387 Grade 9 Steel Plate SA387 Grade 9 Steel Plate – weldable carbon steel plates for pressure vessels and boilers used in elevated temperatures. The material benefits from added chromium and molybdenum which gives the steel greater corrosion resistance and resistance to heat. SA387 Grade 9 is used by fabricators who serve the oil, gas and petrochemical industry.

The ASME SA387 standards covers the supply of weldable chrome molybdenum alloy steel plates for pressure vessels used in elevated temperature service.

The added molybdenum and chromium provides excellent corrosion resistance and high temperature resistance respectively.

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 pressurized vessels, industrial boilers, heat exchangers and Pipe work.

We can supply:
Thickness from 5mm to 150mm
Width: from 1,500mm to 2,500mm
Length: from 6,000mm to 12,000mm

This specification covers chromium-molybdenum alloy steel plates for welded boilers and pressure vessels designed for elevated temperature service. Materials considered under this specification are available in grades 2, 12, 11, 22, 22L, 5, 9 and 91. The steel materials shall be killed and shall be thermally treated. The steel specimens shall undergo heat analysis and product analysis and shall conform to the chemical requirements for carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, nickel, vanadium, columbium, boron, nitrogen, aluminum, titanium, and zirconium. The steel specimens shall also undergo tension tests and shall conform to the required values of tensile strength, yield strength, and elongation.

This specification covers molybdenum alloy steel plates, intended particularly for welded boilers and other pressure vessels. Plates under this specification are available in three grades having different strength levels: Grade A; Grade B; and Grade C. The steel shall be killed. The steel shall conform to the chemical requirements specified. Tension tests on plates shall conform to the requirements specified. Plates under this specification are available in three grades having different strength levels as follows:

Sourced from some of Western Europe's & Asia's finest steel mills, Prosaic Steel & Alloys stock a wide range of ASME SA387 Class 2 plates which are available for shipment worldwide.

ASTM A387, 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.
