What is High Strength Steel Plate?

The High Tensile Steel Plates is one such plate made of steel which possesses high strength. They also come with improved formability and weldability. The High Yield Steel Plate shows good resistance to atmospheric corrosion, and has enhanced properties compared to the conventional steel products. The High Yield Strength Steel Plate is in demand due to several reasons, like its structural section can easily be reduced by increasing the strength of the material.

This also helps reduce the fabrication and erection cost. Using the High Strength Stainless Steel Plate can also help reduce the size of any structural element and thus these plates can be used for developing aesthetically pleasing products. The strength of the High Strength Carbon Steel Plate can be increased by the addition of elements like carbon and manganese in its chemical composition, but this might impact the fabricability. The Ultra High Strength Steel Plate is light in weight and can be used in various industries like automobiles for production of trains, buses, trucks, and planes.


What are High Tensile Steel Plate Grades ?

The High Tensile Plate, as the name suggests, possesses high tensile strength ranging between 590 to 980 N/m2. Different types of High Tensile Steel Grades In India are available for clients to use for different purposes. They have a high weldability and come with guaranteed low temperature (-40 degrees C) toughness. By looking at the High Tensile Steel Grades Chart, one can easily notice that they are generally available with a very high thickness of over 100 mm.


What is High Tensile Steel Density ?

The High Tensile Steel possesses a yield strength ranging between 50,000 to 100,000 pounds/inch2.
