Carbon Structural Quality Steel Plate

Carbon Steel plate is the best choice in the fabrication of numerous shapes and applications. Commonly used in the construction of bridges, buildings and ships, it's also utilized in the fabrication of base plates, braces, liners, brackets and storage tanks.

This steel is very receptive to numerous workability requirements and can be, welded, formed, machined, sheared, drilled, sawed, punched, bolted and riveted.

Common applications for the carbon grades include gears, sprockets, cutting edges, scraper blades, construction & farm equipment parts and other machined components.

A829-4140

Standard Specification for Alloy Structural Steel Plates

This specification covers structural quality alloy steel paltes that are usually specified to chemical composition requirments, but tensile properties may also be specified. When tensile properties are required, the specific requirements must be comapatible with the chemical composition, condition and plate thickness. Plates can be supplied in the following conditions: As-Rolled, Annealed, Normalized and Normalized and Tempered.

  • Chemical Requirements:
  • Carbon Range of .36 to .44
  • Manganese Range of .75 to 1.00
  • Phosphorous .035 max
  • Sulfur .040 max
  • Silicon range of .15 to .35
  • Chromium range of .80 to 1.10
  • Molybdenum range of .15 to .25
  • Mechanical Requirements:
  • Available when requested at time of order

A36

Standard specification for Carbon Structural Steel.

This is one of the most common carbon structural steels used in the plate fabrication industry. Its uses vary but it can be riveted, bolted or welded in the construction of bridges and buildings, and for general structural purposes.

Chemical Requirements:

Carbon up to .29 maximum depending on thickness
Manganese range of .80 to 1.20 depending on thickness
Phosphorous is .04 maximum
Sulfur is .05 maximum
Silicon range of .15 to .40 maximum depending on thickness

Mechanical Requirements:

Yield Strength is 36,000ksi minimum
Tensile Strength can range from 58,000ksi to 80,000ksi
Elongation in 2" test is 23% minimum
Elongation in 8" test is 20% minimum

A516

Standard Specification for Pressure Vessel Plates, Carbon Steel, for Moderate and Lower Temperature Service

This specification covers carbon steel plates intended primarily for service in welded pressure vessels where improved notch toughness is important. Plates 1.50" and under in thickness are normally supplied in the As-Rolled condition. The plates may be ordered normalized or stress relieved, or both. Plates over 1.50" in thickness will be normalized.

Chemical Requirements:

Carbon range is .18 to .31 depending on grade & thickness
Manganese range is .60 to 1.30 depending on grade & thickness
Phosphorous maximum is .035
Sulfur maximum is .035
Silicon can range from .15 to .40

Mechanical Requirements:

Grade 55 - 30,000ksi yield strength, 55,000ksi to 75,000ksi tensile strength, 23% elongation in 8' test, 27% elongation in 2" test. Maximum thickness is 12'.
Grade 60 - 32,000ksi yield strength, 60,000ksi to 80,000ksi tensile strength, 21% elongation in 8" test, 25% elongation in 2' test. Maximum thickness is 8".
Grade 65 - 35,000ksi yield strength, 65,000ksi to 85,000ksi tensile strength, 19% elongation in 8' test, 23% elongation in 2' test. Maximum thickness is 8'.
Grade 70 - 38,000ksi yield strength, 70,000ksi to 90,000ksi tensile strength, 17% elongation in 8' test, 21% elongation in 2' test.
Note - Mechanical requirements are minimums unless there is a range listed.

These grades are produced for structural applications such as bridges, buildings, and many structural end uses.
