ASTM Steel Plates

ASTM Steel Plates

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

ASTM A283 plate is a low carbon steel that is strong and formable.

It is easy to machine and fabricate and can be securely welded by all welding methods.

It is used in riveted, bolted, and welded construction of bridges and buildings, and for buildings, including pre-fabricated buildings, warehouses, and industrial and commercial structures

SPECIFICATIONS

  • 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.

GRADES

Grade 4140 and Grade 4142 are quenching and tempering steels in accordance with American codes of practice for the mechanical-engineering and tool-making fields, with a defined hardness range, unlike steels in accordance with the American standard.

  • ASTM A829 Grade 4142

These two quenching and tempering steels in accordance with ASTM A829 are comparable to a 42CrMo4 as specified in EN 10083, Part 3.
Above and beyond the applicable standard, these products are also tested for additional application-specific properties.
We supply Grade 4140 and Grade 4142 entirely to meet your requirements, in various delivery states and with precisely defined hardness ranges, up to plate thicknesses of 300 mm.
These steels convince users with their excellent cleanness and homogenous microstructure, precisely defined hardness and mechanical-strength range in delivery state. These assure low tool wear and good machinability.

Differences Between ASTM A529 & A572

The American Society for Testing and Materials standardizes, among other things, the composition and mechanical properties of steel. While many forms of steel possess similar compositions, such as A529 and A572, relatively small differences in the quantities of particular elements are enough to make the steels have different mechanical properties, and therefore, different applications.

Chemistry
In terms of chemistry, A529 and A572 have very similar elemental composition. A572 has a carbon content of about .21 percent, a manganese content of 1.35 percent, a phosphorous content of .04 percent, a silicon content of .3 percent and a sulfur content of .05 percent. In comparison, A529 steel has a content of .27 percent, a manganese content of 1.2 percent, a phosphorous content of .04 percent and a sulfur content of .05 percent. Additionally, A529 has copper added (.2 percent) and lacks silicon.

Mechanical Properties
Mechanically, A572 and A529 are very similar. A572 has an ultimate tensile or breaking strength of 60,200 pounds per square inch, a tensile yield strength of 42,100 psi and a shear modulus of 11,600 ksi. A529 possesses an ultimate tensile strength of 72,500 psi, a tensile yield strength of 42,100 psi and a shear modulus of 11,600 ksi. The additional ultimate tensile strength is partly due to the addition of copper and slightly higher carbon content of A572.

Uses
With such similar chemistry and nearly identical mechanical properties, A529 and A572 steel are used interchangeably in most applications. Both steels are typically available in plate and bar form. Because both types of steel can be easily welded and riveted, they are typically used in the construction of buildings, bridges and other structures.
