ASTM A387 GRADE 12 CLASS 2 | ASME SA387 GRADE 12 CLASS 2

 

ASME SA387 Grade 12 Class 2 and ASTM A387 Grade 12 Class 2 Chrome Molybdenum Steel Plates :

A387 Grade 12 Class 1, A387 Grade 12 Class 2 are under steel specification standard ASTM A387 / A387M for pressure vessel steel plates, alloy steel with Chromium-Molybdenum. The equal steel plate SA387 Grade 12 Class 1 and SA387 Grade 12 Class 2 are under American steel standard SA 387 / SA 387M. All these alloy steel plates intended primarily for Welded Boilers, Pressure Vessels & Tanks. Rolling maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. 

For pressure vessel steel plate SA387 Grade 12 CL 1, the tensile strength shall be within 380 to 550, minimum yield strength is 230 Mpa. For SA387 Grade 12 CL 2 pressure vessel steel plate, the tensile strength is at 450-585 Mpa and yield point shall be above 275 Mpa. Besides the five main elements, Cr-Mo is also in the chemical composition for these alloy steels.

We Presinox Impex supply high quality ASME SA387 Gr12 Class 2 and ASTM A387 Gr12 Class 2 Chrome Moly pressure vessel steel plates from various origins such as Korea, Japan, China, Eastern European, Western European and USA. A387-12-2 and SA387-12-2 are killed and thermally treated as requested by ASTM A387 and ASME SA387, both SA 387 and A 387 are described as "Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum". The specification covers alloy steel plates intended primarily for welded boilers and pressure vessels designed for elevated temperature use, due to its 1.25% Chromium, 0.5% Molybdenum and effective working temperature up to 575°C, this steel grade has been widely used in the variety of industries and is significantly superb particularly in Oil and Gas, Petrochemical and Power Plant where high temperatures is a must for the industries. The high level of chromium provides Excellent Corrosion and Oxidation Resistance, compelling in sour gas applications. This effectively stops the corrosive agents from dissolving the iron out of the steel structure.
