ASTM 709 Structural Steel Plates Tensile Requirement

Strength, Yield Strength ksi (MPa), Tensile Strength ksi (MPa): Stronger, 58-130 (400-900)

Formability: % Elongation: Low for some grades, 14-21%

For better formability consider Drawing Steel

Joining – Fair

Design and welding must account for stresses.

Corrosion Resistance – Good   

Galvanizing will slow corrosion.   For longer life in harsh chemical conditions, consider Galvanized or Coated Steel

Chemistry – Low carbon, high manganese and silicon, alloyed with copper, Chromium, Nickel, and Molybdenum

Cost – Higher.  

Good when thinner or stronger steels will add value.
