ASTM A242 steel

Product introduction

The  ASTM A242 specification is the standard specification  for high-strength low- alloy structural steel for structural members where weight savings and atmospheric corrosion resistance are important.  Mechanical property requirements are specified by  product type (plates and bars, and structural Shapes) and by thickness.

ASTM A242 steel has atmospheric corrosion resistance
The steel plate under ASTM A242 standard also called the weathering steel plate, referred to the semi-killed or fully killed steel. It has good atmospheric corrosion resistance so the steel could be used in a lot of working environments.

ASTM A242 weathering steel is substantially better than that of carbon structural steel with or without copper added-in.

Mechanical properties A242:
Tensile:
70 ksi min (3/4 and under), 67 ksi min (3/4-1.5) 63 ksi min (over 1.5-4)
Yield:
50 ksi min (3/4 and under), 46 ksi min (3/4-1.5) 42 ksi min (over 1.5-4)
Elongation:
16% min in 8” 19% min in 2” (for plates wider than 24”)
