ASTM A302 Alloy Boiler Plate
ASTM A302 is a low alloy steel specification covering 4 different grades (A, B, C, D) especially for welding boilers and other pressure vessels.
Grades C and D contain chemical composition Ni, with the same thickness, Grade C has the same yield and tensile strength as Grade B, while Grade C has a higher elongation. It is manufactured for pressure vessels, boilers, tanks and heat exchangers in oil and gas projects.
