Tensile strength mpa of EN steel grade S275JR material sheet structural
Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.
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 EN steel grade S275JR material general weldments that do not need heat treatment.

ArcelorMittal said it was taking measures to cut its North American EN steel grade S275JR material steel production in response to the weakening demand for downstream steel after the outbreak of covid-19, foreign media reported. It is reported that ArcelorMittal's plant in the port of Indiana is ready to shut down the No. 4 blast furnace.
