ASTM A514 GR J Quenched and Tempered Steel Plate supplier

ASTM A514 GR J Quenched and Tempered Steel Plate

If you're looking for a steel plate with very high strength and good toughness in thin sizes, ASTM A514 GR J quenched and tempered steel plate is a good option. It's designed for jobs where you need light weight but strong material, like in pressure vessels or structural parts.

This steel does well in welding and shaping. At Gangsteel, we produce and export quality ASTM A514 GR J plates. We heat them to high temps, cool fast to harden, then temper to add toughness. Our plates follow international rules and are tested for your projects.

What is ASTM A514 GR J Steel Plate?

ASTM A514 GR J is an alloy steel plate that's quenched and tempered for extra strength. It's part of the A514 group, with metals like nickel and molybdenum to make it tough.

It's best for thin plates up to 1.25 inches. Gangsteel makes these plates easy to use in designs for high-pressure equipment or welded structures.

ASTM A514 GR J Specification

The ASTM A514 standard covers strong steel plates for welding in tough spots. Grade J is for thin plates, with high yield strength.

At Gangsteel, our plates meet ASTM A514/A514M fully. This includes heat treatment and tests. We can add impact tests if needed.

Supply Specifications

Gangsteel has flexible sizes for ASTM A514 GR J plates to fit your work. We have standard and custom options.

We can change for your needs.

Chemical Composition

The elements in ASTM A514 GR J give it high strength. We check during melting (ladle) and on finished plate (product). Small changes are allowed.

Here's the table:

This mix makes it strong and weldable.

Mechanical Properties

ASTM A514 GR J has strong features for hard work. It includes yield strength, tensile strength, elongation, hardness, and impact in cold (Charpy).

Our plates are good for pressure and stress.

For thicker, yield may be lower.

Applications of A514 Grade J Steel Plate

Gangsteel's ASTM A514 GR J plate is used in places needing high strength in thin material. It's for pressure vessels and tanks that hold high pressure.

It's also in structural parts for machines and buildings. We've supplied GR J for global projects in energy and engineering.
