Spiral steel pipe raw materials
Hot-rolled plate, that is, hot-rolled steel rolled steel plate or strip, commonly known as hot plate, usually also rolled written as the word tie, such as hot-tied plate, but all refer to the same hot-rolled plate. Refers to the width greater than or equal to 600mm, the thickness of 0.35-200mm steel plate and thickness of 1.2-25mm steel strip. Cold rolled plate is made from hot rolled coils and rolled at room temperature under recrystallization temperature.
Spiral steel pipe raw materials for strip or coil are hot-rolled plate.
The difference between hot-rolled plate and cold-rolled plate.
Hot rolled steel plate is divided into structural steel, low carbon steel, welded bottle steel, followed by a variety of steel to find the steel you need, in checking the density and composition of a particular steel .
Hot-rolled steel plate has low hardness, easy processing, and good ductility.
