Supply the S355K2 steel material grade

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of S355K2 steel material circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and S355K2 steel material management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

NM450 material is mainly to provide protection in occasions or parts where wear resistance is needed, so that the life of the equipment is longer. Then it can reduce the maintenance and downtime brought by maintenance, and accordingly reduce the investment of funds. S355K2 steel material, NM450 wear-resistant steel plate is widely used in engineering machinery, mining machinery, coal mine machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.

The cold working performance of S355K2 steel material and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of S355K2 steel material and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.

Ultrasonic flaw detection emits ultrasonic waves to the S355K2 steel material steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the S355K2 steel material steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

S355K2 steel material, Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.
