HR black nm450 plate impact resistance dimensions

Both NM500 and WRZ400A are used in construction machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other manufacturing enterprises, used in excavators, loaders, bulldozers, bucket plates, blades, side blades, blades, crusher liners Wait. At present, BBN STEEL produces NM500, NM450, NM450 plate impact resistance and NM400 not only to meet the needs of domestic industrial and mining manufacturing, but also a large number of exports to Europe, the United States and other countries.

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 NM450 plate impact resistance 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.

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, NM450 plate impact resistance and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

The effect of nitrogen (N) on the properties of NM450 plate impact resistance and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in NM450 plate impact resistance and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
