What is special-shaped nm400 mechanical properties
The company has allocated special environmental protection facilities for all NM400 mechanical properties pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, NM400 mechanical properties steel mill scale, environmental protection dust has reached 100%.
EH500 steel plates and EH550 steel plates are both ultra-high-strength structural steel plates for ships and oceans. The addition of microalloying elements can not only improve the strength, compensate for the strength loss caused by the reduction of carbon equivalent, but also improve the welding performance, mechanical properties and process performance of the steel NM400 mechanical properties. Due to the use environment requirements of EH500 steel plate and EH550 steel plate, it can meet the requirements of high strength, high toughness, high welding performance, and thickness direction performance.
For Q345B steel plate, Q stands for the yield of Q345B material. The 345 at the back refers to the yield value of Q345B material, which is about 345MPa. The yield value will decrease with the increase of Q345B steel plate thickness. Q345B steel plate has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability. It NM400 mechanical properties is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.
The addition of Ca element in steel such as NM400 mechanical properties can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of NM400 mechanical properties, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.
The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality NM400 mechanical properties products and excellent services. Our company's products NM400 mechanical properties are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.
Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
