Products Description
ASTM A387 GR 11 CL 2 Alloy Steel Plates is applicable in many industries and general purposes such as the oil & gas industry, petrochemical industry, boilers & heat exchangers, shipping, automobile ancillaries, steel plants; cement industry, sugar industry, nuclear & aerospace pants, centrifugal industry, steel plants, port building, wastewater management, paper & pulp industry, and infrastructure building. Alloy GR 11 is useful in raising temperatures because it can handle high temperatures. The addition of chromium gives amazing corrosion and oxidation resistance. This corrosion resistance is crucial for sour gas applications. ASTM A387 has higher flexibility, durability, longevity, good dimensional accuracy, weldability, excellent surface finishing, higher tensile strength, sturdiness, and can withstand heavy loads. ASTM A387 GR 11 CL 2 Plates can entirely stress cracking corrosion resistance, crevice corrosion resistance, and pitting resistance.
Alloy CL 2 is useful at high temperatures services. Adding molybdenum and chromium gives the plate resistance to high heat and good corrosion resistance in seawater. The molybdenum coating provides resistance to rust and iron substances. These plates are highly effective and useful in gas and heat services. ASTM A387 GR 11 CL 2 Low Carbon Steel Plates got through many tests after production from the industry, such as a 100% radiography test, mechanical test, chemical test, hydrostatic analysis, x-ray test, firmness test, flaring test, flattening test, hardness test, impact analysis, positive material recognition test, reduction test and many more.

What is SA 387 Grade 11 Class 2 equivalent to?
Sa 387 Gr 11 Equivalent Material is the ASME SA387 in the US markets with the European Union having modules in 13CrMoSi5-5 grade. The Sa 387 Gr 11 Cl 2 Equivalent Material is the SA387-11-2 of the ASME and ASTM standard.
What is A387 Grade 11 material?
ASTM A387 Gade 11
The ASTM A387 specification is the Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum intended primarily for use in welded boilers and pressure vessels designed for elevated temperature service.
What is ASTM A387 material equivalent to?
Among the ASTM A387 Grade 22 equivalent steel grades, SA387 Grade 22, 10CrMo9-10 is more popular than other equivalents. SA387 Grade 22 steel is under ASME SA387/ SA387M standard. The chemical performance and technical requirements of SA387 Grade 22 steel is almost same with ASTM A387 Grade 22 steel.
What is the composition of A387 steel?
Composition: ASTM A387 steel plates typically contain chromium (up to 9% or more) and molybdenum (up to 2.25% or more), which enhance their strength and corrosion resistance at high temperatures.
What is A387 grade 22 material?
The A387 Grade 22 Class 2 – a grade of chromium-molybdenum alloy – is mainly intended for use in pressure vessels and welded boilers, which are designed for use in elevated temperature service.
