What are the physical properties of SPHD?

Physical properties——

Density: 7.85 g/cm3

Melting point: 1420-1460°C

Hardness: The hardness of SPHD steel plate is determined by the heat treatment process of the steel plate. Hardness can vary depending on the desired properties required for the final product. However, in general, SPHD steel is much harder than other types of steel due to its higher carbon content.

What are the available sizes of SPHD steel plates?

SPHD hot rolled steel plates are available in a variety of sizes to suit a variety of applications. The most common size is 2,000mm x 1,200mm, but other sizes are also available upon request.

The thickness of SPHD hot rolled steel plate also varies from 3mm to 100mm. The thickness of the steel plate will determine the overall strength and durability of the finished product.

What are the characteristics of SPHD steel plate?

SPHD hot rolled pickling plate

The SPHD pickling plate is made of high-quality hot-rolled coil as raw material. It is made of black iron sheet or steel plate, and then the steel oxide scale on the surface is removed by pickling by the pickling unit. In this way, the surface quality of the SPHD pickling plate is improved. The smoothness is greatly improved, and the steel looks more beautiful.

In addition, SPHD steel plate also has the following excellent features:

*Easy to form

*Excellent solderability

*Good dimensional accuracy

* Good mechanical properties

What is the difference between SPHD steel plate and SPHC steel plate?

SPHD steel plate is a hot-rolled low-carbon steel plate with good mechanical properties and low carbon content. The chemical composition of SPHD steel is similar to SPHC steel except for the carbon content. The difference in carbon content between SPHC and SPHD steels affects weldability and the mechanical properties of the finished product. The tensile strength, yield strength, elongation and impact toughness of SPHD steel are lower than those of SPHC steel. The weldability of SPHD steel is slightly lower than that of SPHC steel.
