ASTM A514 GR K Quenched and Tempered Steel Plate supplier

If you're looking for a steel plate that's very strong and can save weight in big machines, ASTM A514 GR K quenched and tempered steel plate is a smart choice. It's made for places where you need high strength without adding too much weight.

This steel is good for welding and shaping. At Gangsteel, we make and export top ASTM A514 GR K plates. We heat them hot, cool them quick to harden, then temper to make them tough. Our plates meet world standards and are tested well for your work.

What is ASTM A514 GR K Steel Plate?

ASTM A514 GR K is an alloy steel plate quenched and tempered for high strength. It's in the A514 family, with elements like molybdenum and boron to boost toughness.

It's best for thicknesses up to 2.5 inches, where it keeps strong under load. Gangsteel makes these plates easy to use in designs for heavy equipment or structures.

ASTM A514 GR K Specification

The ASTM A514 standard covers high-strength plates for welding in construction or machines. Grade K focuses on plates up to 6 inches, but full strength up to 2.5 inches.

At Gangsteel, our plates follow ASTM A514/A514M rules. This includes heat treatment and tests. We can add low-temp impact tests if you need.

Supply Specifications

Gangsteel offers many sizes for ASTM A514 GR K plates to match your needs. We do standard and custom.

Chemical Composition

The mix in ASTM A514 GR K makes it strong and weldable. We check during melting (ladle) and on finished plate (product). Small changes allowed per ASTM.

Here's the table:

This helps resist cracks.

Mechanical Properties

ASTM A514 GR K has great strength for heavy jobs. It includes yield (bend resistance), tensile (pull strength), elongation (stretch), hardness (wear tough), and cold impact (Charpy test).

Our plates work in stress and cold.

Applications of A514 Grade K Steel Plate

Gangsteel's ASTM A514 GR K plate is used where strength saves weight. It's in building construction for beams and supports.

It's also in cranes and big machines that carry heavy loads. Mining equipment and trucks use it too. We've sent GR K plates worldwide for these.
