Alloy A387 plates are suitable for condensers, oil drilling, refineries & fertilizer industry, petroleum industry, and general purposes such as large metallic tanks, oxygen cylinders, etc.
ASTM A387 GRADE 12 CL.2 Plates are useful in corrosion and heat resistance. Alloy Gr 12 has high resistance to corrosion and heat after the addition of chromium and molybdenum. CL 2 Plates have some amazing properties, such as durability, sturdiness, and corrosion resistance. GR 12 Plates are designed to be useful in raised temperatures. Plates Gr 12 can withstand the high temperatures, retaining properties primarily intended for pressure vessels and welded boilers at the high raised temperatures. Grade 12 plates have high tensile strength levels and resistance from crevice corrosion and plate cracking corrosion at high temperatures. Alloy CL 2 plates can withstand the corrosion of rust and seawater.
ASTM A387 GR 12 CL 2 pressure vessel plates undergo many tests and inspections after manufacturing, such as hydrostatic test, firmness test, x-ray test, Spectro analysis, positive material recognition test, ultrasonic test, 100% radiography test, hardness test, flaring test, micro test, macro test, intergranular test, impact test and many more.

FAQ
Q: What is SA 387 material?
A: A high quality chrome molybdenum alloy steel plate intended specifically for use in weldable carbon steel pressure vessels at elevated temperatures. Added molybdenum gives the material greater temperature tensile strength and the chromium provides improved corrosion resistance.
Q: What is SA387 grade 11 equivalent to?
A: 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.
Q: What is the difference between SA387 Grade 11 Class 1 and Class 2?
A: The difference between SA 387 Grade 11 Class 1 and Class 2 Plate lies in their mechanical properties. However, they both have the same chemical composition. The tensile strength and yield strength of class 2 material is higher than that of class 1, whereas the elongation for class 1 is higher compared to class 2.
Q: What is the temperature range for SA 387 GR 11?
A: In the lower end of the temperature range SA 387 Gr 11 (1150 °F min tempering temperature) , and SA 387 Gr 22 (1250 °F min tempering temperature) are used. These grades can be specified in either class 1 or 2 and can also be provided in the Normalized & Tempered or Quenched and Tempered.
Q: What is SA 387 GR 9 material?
A: SA 387 GR 9 is a chromium-molybdenum alloy steel widely used in high-temperature applications such as pressure vessels and power generation equipment and it provides excellent resistance to oxidation and creep, making it ideal for long-term service at elevated temperatures.
Q: What is the chemical composition of SA 387 GR 22?
A: 22 CL. 2 plate chemical composition includes Chromium (Cr) 2%, Molybdenum (Mo) 1%, Manganese (Mn) 0.5%, Silicon (Si) 0.5%, Phosphorus (P) 0.03%, Sulfur (S) 0.03%, and Carbon (C) 0.1%.
Q: What is the equivalent material of SA 387 GR 12?
A: Sa 387 Gr 12 Equivalent Material can be classified as Asme SA 387 for the USA, for the European Union, the equivalent grade to this material is EN 13CrMo4-5. In Germany and England, the equivalent grades are DIN 13CRM044 and BS 620B, respectively. Apart from this, the equivalent grade for France is AFNOR 36206 15CD2.
