What is nm450 mechanical properties equivalent steel grade in China

Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.

Normal strength shipbuilding structural steel is divided into four grades: A, B, C, and D. The yield strength (not less than 235N/mm^2) of NM450 mechanical properties these four grades is the same as the tensile strength (400~520N/mm^2). However, the impact properties of steel plates at different temperatures are different.

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the NM450 mechanical properties product workpiece, thereby improving the production efficiency and production processing quality.

Hot rolled NM450 mechanical properties product stock size: 12*1600*91000, 25*1950*10250, 25*1950*10150, 14*2000*10000, 12*1600*10000, 16*1500*9340, 60*2020*6100, 25*1950*9700, 14*2000*13500, 75*2390*4320, 16*1500*9340, 50*2740*13460, 20*2100*10700, 20*2500*6200, 60*1750*9100, 34*1900*12000, 12*2050*5100, 45*2010*10000, 25*2100*8650, 70*2270*7600, 16*1500*9340, 6*1950*10000, 30*2000*7630, 20*2100*11600, 70*2260*7950, 34*1900*12000.

Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.

The steel plate, steel pipe and other steel materials are the important material in the material engineers. Our company will provide the high quality the steel plate, steel pipe and other steel materials for you. We are exported the steel plate, steel pipe and other NM450 mechanical properties steel materials to the customers from USA, South America, Europe, Africa etc. If we can have the good cooperation together, you will be very welcome to be our agent in your local market. Let’s work together!
