A514-B Plate

From the boom cranes that lift weighty loads to the trucks and trailers that haul precious cargo from one destination to another, ASTM A514-B steel plate keeps commerce moving. This lightweight yet tough alloy steel grade is ideal for use in challenging environments.

Universal Steel America supplies A514-B steel plate with thicknesses from 1/4 to 8 inches and in the quench-and-tempered condition. It’s classified as a high-strength-low alloy, or HSLA, material grade. It has a minimum yield strength of 100 kilopounds per square inch, or KSI, up to 2-1/2 inches thick, and a 90 KSI minimum yield strength from 2-1/2 to 8 inches thick.

Benefits of ASTM A514-B Steel Plate

A514-B is a quenched and tempered alloy steel plate with an appealing combination of good weldability and robust toughness at low atmospheric temperatures. A high yield strength makes this material grade ideal for structural, construction, heavy equipment, and transit projects, which often require lightweight steels that don’t sacrifice longevity or resilience. Additional characteristics of A514-B steel plate include: 

  • Impact resistance 
  • High strength
  • Fair grinding and machining potential
  • Corrosion resistance 
  • Durable
  • Long-term economy 
  • Abrasion resistance 

Typical Applications

A514-B steel plate, which is sometimes called T-1 steel plate, is commonly used for the manufacture or fabrication of parts that require a higher strength at a reduced weight. Typical applications include:

  • Hauling devices
  • Transport trailers
  • Storage container support frames
  • Bucket components
  • Heavy vehicle frames and chassis
  • Construction equipment
  • Crane booms
  • Large tooling

A514 Steel Plate Requirements

Upon request, this material grade is also available with additional Charpy impact testing, or CVN examination. Also called the Charpy V-notch test, it measures the amount of energy absorbed by the specimen during fracture and helps show whether a metal is brittle or ductile. This high strain-rate assessment involves striking a standard notched specimen with a controlled weight pendulum swung from a set height. 

A514-B steel plate is not generally recommended for service at temperatures lower than -50 degrees Fahrenheit, or -46 degrees Celsius, since its toughness is not sufficient to prevent brittle fracture at lower temperatures. This material type is also not recommended for service at temperatures higher than 800 degrees Fahrenheit, or 425 degrees Celsius, because fracture could result from low stress-rupture ductility at higher temperatures.
