What is EN steel grade S450J0 material physical properties

Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business EN steel grade S450J0 material department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and EN steel grade S450J0 material after-sales service department constitute the service customer network.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with EN steel grade S450J0 material, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the EN steel grade S450J0 material and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.

The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the EN steel grade S450J0 material steel materials can be shipped immediately after passing the quality inspection.
