ASME Material Specification and Grades for Pipes, Tubes, Forgings, Castings, Fittings, Valves, Nuts and Bolts

For the complete identity of a material we need two things;

1. Material Specification 
2. Material Grade

For Example, In SA 106 Gr.B the “SA106” is the material specification, and “Gr.B” is the grade of the material.

Please note that for a particular specification there may be more than one grade. For example, SA106 has three grades i.e. Grade A, Grade B, and Grade C.

In this article, The Material Specification & Grades has been explained, as per ASME Sec II, for the following Items/commodities;

1. Pipes

2. Tubes

3. Forgings

4. Castings

5. Fittings

6. Valves

7. Nuts and Bolts
