Kloeckner Metals offers A709 steel plate in grade 50W. This steel plate is often stocked in the flat-rolled, as-in condition. It is excellent for building bridges and similar applications.
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.
If it is properly designed, it can be used for many applications in the unpainted condition including:
Its machinability is fair. Since it is an alloy steel, it is tougher to machine than plain carbon steel.
It is weldable by all conventional methods.
Heat treatment is not required.

ANSWER:
ASTM A709 is the standard specification for structural steel that is used in bridges. It includes carbon steel plate, HSLA steel plate, and quenched and tempered (Q&T) steel plate, all used as structural steel in the construction of bridges.
ANSWER:
It is a standard specification for structural steel in bridges with weathering capabilities. With a corrosion index of 6.0 or higher, ASTM A709-50W has substantially better atmosphere corrosion resistance than carbon steels even with the addition of copper.
ANSWER:
HPS stands for “high performance steel” and is a designation given to steels that promise better performance in tensile strength, weldability, cold formability, toughness, and corrosion resistance compared to other mild steel grades. Some HPS steels are interchangeable with the American standard ASTM grade.
