Cutting of S275JR steel plate

S275JR steel plate is the most common European steel plate material and has a wide range of uses. S indicates the grade of the European standard steel plate - 275 indicates the yield strength of the steel plate - JR indicates the grade of the steel plate corresponds to the impact temperature at room temperature. S275JR steel plate is mostly used for welding large structural parts and steel structures, or for cutting large parts. The delivery state of S275JR steel plate is hot rolling.

Flame cutting can be used for thickness of S275JR that between 8mm and 500mm; plasma or laser cutting can be used for thin plates. Parts with high precision requirement can be cut for thick plates after finished, or using high precision cutting methods such as wire cutting and water cutting , The cutting speed is slow but the cutting precision is high, and it has smooth cutting surface and high verticality.
