A588 Grade K HSLA Steel,S235JR is a European standard non alloy structural steel, equivalent to the national standard Q235B, i.e. S235JR steel is carbon structural steel with low carbon content. S235JR steel is widely used in welding, bolt connection and riveting structures. S235JR steel is mainly used in railway, bridge, all kinds of construction engineering, manufacturing all kinds of metal components bearing static load and unimportant mechanical parts and A588 Grade K HSLA Steel general weldments that do not need heat treatment.A588 Grade K HSLA Steel
Special boiler steel is derived from carbon structural steel, . The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.
The hot rolling method is to heat the steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of rolling process is usually called semi-finished product production, also called blank production.
