For employees' development, the company's transformation and development provides employees with a broad career development platform. The company needs "lion-type" entrepreneurial leaders who are full of entrepreneurial enthusiasm and dare to self-renovate. They also need a large number of professional and professional high-quality talents, and employees can get full capacity to display opportunities.
High strength wear-resistant plate is a kind of plate product used for large area wear condition. It is made by overlaying a certain thickness of high hardness and excellent wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. After production, the high-strength wear-resistant plate will be tested for its strength and bearing pressure. High strength wear-resistant plate is very wear-resistant, in the case of no accident, the service life of NM400 steel properties, high-strength wear-resistant plate is very long.
The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, NM400 steel properties. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.
The weldability of NM400 steel properties is good. It means that under certain process and construction conditions, NM400 steel properties can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel NM400 steel properties plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another NM400 steel properties magnificent projects.
