What data needs to be confirmed for tensile strength of nm500 cutting

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of tensile strength of NM500 nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of tensile strength of NM500 steel, can be used as an alloying element of low alloy steel.

With the continuous development of foreign business, our company has achieved pleasant cooperation with a number of freight companies, including international air transport (including international express) and sea bulk cargo, we can provide the best service. In order to better develop the air transport from mainland to foreign countries, so that the goods can be transferred in Hong Kong in a timely manner.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This tensile strength of NM500 rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products tensile strength of NM500 are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
