What is SA588 Gr B carbon steel plate sheet equivalent IS standard grade

SA588 Gr B carbon steel plate sheet plate weight: 1) Theoretical weight of SA588 Gr B carbon steel plate sheet plate: The theoretical weight of a steel plate is the weight calculated based on the nominal size and density of the steel plate (previously called specific gravity). It is closely related to the length, size, and cross-sectional area of the steel plate. 2) The actual weight of SA588 Gr B carbon steel plate sheet plate: The actual weight of the steel plate refers to the weight obtained through actual weighing, which is more accurate than the theoretical weight.

Fake and inferior steel plates are easy to scratch because of the simple equipment of the manufacturers of fake and inferior materials, which are easy to produce burrs and scratch the surface of the steel plate. Deep scratches reduce the strength of the SA588 Gr B carbon steel plate sheet, steel plate. The surface of the fake and inferior material is prone to cracks, because its billet is adobe, which has many pores. The adobe is subjected to thermal stress during the cooling process, and cracks are generated, and there will be cracks after rolling.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the SA588 Gr B carbon steel plate sheet steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
