Re: [MW:10330] Basic Question

Dear Friend,

SA means Section A for Ferrous Base Material Specification 

387 it is just a series number in that section for low alloy steel plates

GR means grades

22 type of Grade (Example: 11, 22, etc.)

CL means class (Example: Class 1, 2, etc.)

See QW-422 in ASME Section Section IX.

Regards,
Shaunak

Dear Sir s

As I am a novice, please help in some basics

I have come across a material of Specification
SA 387 Gr22 Class 2

Please tell me what is denoted by 387, Gr 22 and Class 2.
Do these figures have any thing to do with strength or chemical composition?

Also for welding this material to a material of same specification, E9018 B3 is mentioned.

Please tell me what is denoted by B3?


Regards,
prv
