A514-H Plate

When constructing the infrastructure or heavy machinery, balancing performance with the protection of people and the environment is important. Lightweight yet sturdy, ASTM A514-H steel plate is a perfect material for structural applications that must meet stringent codes or guidelines.

Universal Steel America stocks A514-H 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-H Steel Plate

A quenched and tempered alloy steel plate, A514-H exhibits high yield strength, strong weldability, and good toughness at low atmospheric temperatures. This alloy steel grade is designed for an array of construction, heavy equipment, and transit projects. Further characteristics of this material grade include:  

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

Typical Applications

A514-H steel plate, which is sometimes called T-1 steel plate, is commonly used for the manufacture or fabrication of parts that need robust strength while maintaining a low weight. Typical applications that can benefit from A514-H steel plate include:

A514 Steel Plate Requirements

Upon request, we can supply A514-H steel plate that has undergone Charpy impact testing, or CVN testing. It measures the amount of energy absorbed by the specimen during fracture and helps show whether a metal is brittle or ductile. Also known as the Charpy V-notch test, this high strain-rate test involves striking a standard notched specimen with a controlled weight pendulum swung from a set height.
