What’s the feature of Gnee Alloy Steel Plate?

ALLOY STEEL SHEET
GNEE ALLOY STEEL PLATES 74

Alloy steel plates exhibit superior strength compared to carbon steels. The addition of alloying elements enhances the structural integrity and load-bearing capacity, allowing these plates to withstand high stresses and heavy loads.

By annealing, normalizing, quenching, or tempering, improve alloy steel plate mechanical properties, and then achieve the desired hardness, toughness, or strength.

Our Alloy steel plates can be cut into desired sizes and shapes. We can customize size, thickness, dimensions, and special tolerances, ect. This ensures that the alloy steel plates meet the specific needs of the application.

Depending on the specific alloy composition, alloy steel plates can possess good weldability. They can be easily welded using conventional welding techniques, facilitating fabrication and assembly processes.

Each order is packaged according to the customer’s standards, including preparation for export such as wooden case, pallet or according to customer’s requirement. All shipping documentation is provided for Alloy Steel Plate delivery from mill to customer.
