What is the EN 10025 S355M steel surface test

Since its establishment, the company has adhered to the business philosophy of "integrity management, reputation first, mutual benefit", and adheres to the training principles of integrity, innovation and pioneering for its employees. It has long been dedicated to EN 10025 S355M steel steel structure, shipbuilding, boiler vessel manufacturing, machinery manufacturing.

The mechanical properties of hot rolled steel plate are far less than that of cold working and forging, but the EN 10025 S355M steel, hot rolled steel plates have better toughness and ductility. Cold rolled steel plate has a certain degree of work hardening and toughness is low, but it can achieve a better yield ratio, and can be used for cold bending spring leaf and other parts. At the same time, because the yield point of cold rolled steel plate is close to the tensile strength, the danger is not foreseen in the use process, and accidents are prone to occur when the load exceeds the allowable load.

Heat treatment advantages of EN 10025 S355M steel, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.

How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of EN 10025 S355M steel, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.
