What is SA 387 material equivalent to?
The Sa 387 Gr 11 Cl 2 Equivalent Material is the SA387-11-2 of the ASME and ASTM standard. With similar chromium, molybdenum, and chemical content the, Sa 387 Gr 11 Cl 1 Equivalent Material of the BS 621B exhibits identical properties.
SA 387: This is the ASME specification for alloy steel plates intended for welded boilers and pressure vessels.
Grade 11: Indicates the specific chemical composition of the steel, which includes chromium and molybdenum.
Class 2: Specifies a higher tensile strength range compared to Class 1.
What is a 387 gr 11 cl 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 the difference between SA 387 GR 11 cl1 and cl2?
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.
What temperature is SA 387 GR 11?
SA-387 Steel Plates Grade 11 & 22 - American Alloy Steel
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.
