ASTM A283 steel plate /sheet

Specification for Low and Intermediate

Tensile Strength Carbon Steel Plate of Structural Quality
DISCUSSION
ASTM A 283 covers low and intermediate tensile strength carbon steel plates for general manufacturing and constructional applications. This material is normally supplied in the rimmed or semi-killed types of steel and is particularly suitable for the economical
production of assemblies requiring a considerable amount of forming. Variations in low temperature impact properties are great and these steels are not recommended for those applications requiring low temperature notch toughness.
CORROSION RESISTANCE
This material has the same atmospheric corrosion resistance as plain carbon steel but this may be enhanced by the use of copper additions.
WELDABILITY
ASTM A 283 steels can be readily welded, using good shop or field practices by all the usual methods; shielded metal-arc, submerged-arc, gas metal-arc and resistance welding together with suggested preheat temperatures.
GAS CUTTING
ASTM A 283 plates may be gas cut using good shop or field practices. Cutting of this material generally does not require preheating.
FORMABILITY
These steels can be readily cold formed using conventional equipment and good shop practices. Grade A material will provide the greatest cold formability with grades B, C and D providing progressively less formability in that order.
