Impact toughness of s275jr steel sheet

The company adheres to the s275jr steel sheet external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of s275jr steel sheet quality and price and best service for all our customers.

The workpiece prone to deformation should be placed in the middle of the whole s275jr steel sheet steel plate as far as possible, and the distance between the workpiece should be enough. Choose a reasonable cutting sequence, the location of the perforation points should be correct, so as to avoid the deformation of the cutting parts.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the s275jr steel sheet steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of s275jr steel sheet seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

Chemical analysis of 50# steel: C: 0.47-0.55, Si: 0.17-0.37, Mn: 0.50-0.80, P: not more than 0.035, S: not more than 0.035, Ni: not more than 0.30, Cr: not more than 0.15, Cu: not more than 0.25.s275jr steel sheet, 50# steel is mainly used to manufacture mechanical parts with low dynamic load, impact load and good wear resistance, such as forged gear, shaft friction plate, machine tool spindle, engine spindle, roll, pull rod, spring washer, etc.
