A387 Grade 12 Chrome Moly Steel is used for boilers and pressure vessels in hot places. A387 Grade 12 Chrome Moly steel is a boiler plate steel according to the ASTM/ASME Standard A387/A387M. A387 Grade 12 is designed for use in pressure vessels and heat exchangers where there is an elevated temperature. It is described as an alloyed high temperature pressure vessel steel.
A387/SA387 Chrome Moly Plates Gr 5, 9, 11, 12, 22 cl2 UttamChrome Moly plate are ASME SA387 and ASTM A387, Alloy Steel Plate, ASME SA / ASTM A387 Gr 11 Cl. 2, ASME SA / ASTM A387 Gr 22 Cl. 2, ASME SA / ASTM A387 Gr 5 Cl. 2, ASME SA / ASTM A387 Gr 9 Cl. 2., Grade 5 Class 2, Grade 9 Class 2, Grade 11 Class 2, Grade 22 Class 2, Grade 91 Class 2.
The Alloy Steel ASTM A387 Grade 9 Materials are made up of carbon, manganese, phosphorus, sulfur, silicon, chromium and molybdenum.The chromium content in the SA 387 Gr 9 Cl 2 plates ranges from 7.9 to 10.1% and the molybdenum content ranges from 0.85 to 1.15%. The chromium and molybdenum contents provide the heat resistance and corrosion resistance to the Alloy Steel Grade 9 Sheet, ASTM A387
ASTM A387 - SSABASTM A387. The ASTM A387 specification is the Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum plates used in the application of welded boilers and pressure vessels subjected to elevated temperatures. The two grades SSAB produces are available as Class 1
ASTM A387 Alloy Steel Grade 12 Plates manufacturer in A387 Grade 12 Chrome-Moly steel according to the ASME/ASTM standard A387M/A387 is boilerplate. A387 grade 12 is developed for use into the high-pressure vessels and in the heat exchangers where the elevated temperature is there.
ASTM A387 GRADE 11 Class 1 As a pressure vessel grade steel for use in elevated temperature service, is used in a variety of industries and is highly effective, particularly in the oil, gas and petrochemical industry, where liquids and gases are often stored at higher temperatures.

SA387/ASTM A387 GR 12 CLASS 2. Engineered for use in elevated temperature service, ASME SA387 Grade 12 is a chrome molybdenum carbon alloy steel for use in weldable pressure vessels and industrial boilers. The material benefits from added chromium which provides excellent corrosion and oxidation resistance making it ideal for sour service applications in the oil and gas industry.
preheat & post weld heat treatment of SA-387 Gr 11 Class 2 Jun 28, 2012 · Preheat maintenance is not required. Preheat should be 250 F min - 300F recommended. If welding is interrupted, recommend slow cooling under insulation for T > 1/2". Greater adherence to preheat is mandated as thickness and joint restraint increase. Hydrogen embrittlement can and will occur if you do not appreciate the need for preheat.Alloy Steel ASTM A387 Gr. 11 and 12 - Alloy Steel ASTM ASTM A387 steel plate are typically applied in the temperature range from 316 to 593. The elevated temperature properties of these alloy steel plates are still of particular usage, now, ASTM A387 steel plate are manufactured to be fine grain, low silicon, low sulfur, calcium treated and occasionally produced Q&T to give the highest levels of toughness.
