Application and performance of mechanical properties of nm300 steel

The company's main business: ship plate, mechanical properties of nm300 steel low alloy plate, automobile steel, high-strength plate, pipeline steel, boiler steel plate, weathering plate, wear-resistant plate, bridge plate, pressure vessel plate, steel plate, steel processing, etc. The company takes the implementation of high-end, mechanical properties of nm300 steel high-quality, deep processing, strengthening the main business, diversified operation, group operation, enterprise transformation and upgrading as its development strategy, and makes all efforts to be your professional mechanical properties of nm300 steel steel supplier and partner.

Steel materials mechanical properties of nm300 steel can be classified not only by chemical composition, main quality grade, main performance or use characteristics, but also by habit into carbon steel and alloy steel. Carbon structural steel is easy to smelt, has good processability, low price and large output, and can meet the requirements of common parts of general engineering structure in performance. Carbon structural steel mechanical properties of nm300 steel is usually rolled into steel plates and various sections, which are used for mechanical parts such as factory buildings and bridges.

mechanical properties of nm300 steel, 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than mechanical properties of nm300 steel. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel mechanical properties of nm300 steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

Medium and heavy plate mechanical properties of nm300 steel inventory spot: 23*3190*9220, 23*2470*8400, 22.5*3050*7300, 23*3500*10800, 21*3500*8840, 22*3400*11550, 29.5*1750*7150, 25*2500*12000, 27*1500*5000, 36*2720*7950, 27*1920*6000, 25*2630*3300, 26*3480*6000, 27*1800*6000, 23*2430*12370, 22.5*2560*6000, 43.5*1600*6000, 28.5*2500*6700, 32*1850*6000, 27.5*3100*6390, 48.5*1600*6000, 23.5*3300*14000, 33*3500*7050, 50*1600*6000.
