ASTM A709 grade 50 steel plate has good corrosion resistance, low formability for some grades, higher strength, and a higher cost. It is used in many industries, primarily in manufacturing and construction. Its machinability is fair. Since it is an alloy steel, it is tougher to machine than plain carbon steel.

When welding low and medium carbon steels, the 70XX electrodes and E70S-3-6 MIG wires and E7XT-X flux cored electrodes can be used. When welding low alloy 1 1/4 Cr 1/2 Mo and 2 1/4 Cr 1 Mo with up to 0.05% max carbon, typically 8018-B2L / 9018-B3L (L = low carbon) can be used. When welding higher strength alloys or when tempering and quenching ASTM-A709 Standard Specification for Structural Steel Grade 50W [345W], or HPS 50W [HPS 345W] shall not be substituted for Grades 36 , 50  or 50S [345S] without agreement between the purchaser and the supplier. 1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized.
