ASTM Steel Grades are steel plates that meet the exacting standards for specific grades of steel developed by the American Society for Testing and Materials.
Sunny Steel supply Plate to more than ten ASTM Standards. Many of the Standards define multiple grades of steel plate. The Tensile Strength and Elongation of the ASTM Steel Plates are plotted on the graph. The grades are discussed in detail to the right.
ASTM A283
- Strength
Yield Strength ksi (MPa), Tensile Strength ksi (MPa): Strong, 65 (380-550)
For higher strength and lower weight, consider High-strength, Low-alloy - Formability: % Elongation: Better, 23-25%
For better formability consider Drawing Steel - Joining – Very Good
The cheapest and easiest methods can be used: shielded metal arc welding (SMAW, or stick welding), gas metal arc welding (GMAW, or MIG welding), and oxyacetylene welding. A283 steel is also commonly bolted and riveted for buildings and other structures. - Corrosion Resistance – Good
Galvanized ASTM 283 will rust more slowly. For longer life in harsh chemical conditions, consider Galvanized or Coated Steel - Chemistry – A283 is a ‘plain’ steel without expensive alloying elements.
- Cost – Relatively low.
Good when thinner, stronger, or more formable steels will not add value.
ASTM A36
- Strength, Yield Strength ksi (MPa), Tensile Strength ksi (MPa): Strong, 70 (480)
For higher strength and lower weight, consider High-strength, Low-alloy - Formability: % Elongation: Basic, 20
For better formability consider Drawing Steel - Joining – Very Good: 10/10
The cheapest and easiest methods can be used: shielded metal arc welding (SMAW, or stick welding), gas metal arc welding (GMAW, or MIG welding), and oxyacetylene welding. A36 steel is also commonly bolted and riveted for buildings and other structures. - Corrosion Resistance – Good
A36 can be galvanized to slow rusting. For longer life in harsh chemical conditions, consider Galvanized or Coated Steel - Chemistry – A ‘plain’ steel without expensive alloying elements.
