. Low-alloy deformed and plain bars. These bars, which must be marked

with the letter W (for type of steel), are to be used where controlled tensile properties

and/or specially controlled chemical composition is required for welding purposes. They

are available in two grades: 60,000 psi (420 MPa) and 80,000 psi (550 MPa), designated

as Grade 60 (420) and Grade 80 (550), respectively
