hardess of nm500 steel plate sheet suppliers

Our hardess of NM500 steel plate pipeline steel has once again helped the construction of the China-Russia East Line Natural Gas Pipeline. During 2017 - 2018, the company successively supplied more than 10,000 tons of high-grade pipeline steel materials for the northern section of the Sino-Russian Eastern Gas Pipeline project, helping the northern section of the hardess of NM500 steel plate project to be successfully completed. Now we reload the task and will provide API 5L X80 high-grade pipeline steel for the middle section of the China-Russia Eastern Gas Pipeline project.

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.

Whose hardness is higher between No.20 steel and No.45 steel, hardess of NM500 steel plate? Both No.20 steel and No.45 steel belong to high-quality carbon structural steel. According to the characteristics of high-quality carbon structural steel, its carbon content determines the performance of the steel. The higher the carbon content, the higher the hardness and strength of the steel, the lower the plasticity and toughness. The carbon content of No.20 steel and No.45 steel are 0.20% and 0.45% respectively, which shows that the hardness of No.45 steel is higher under the same process.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with hardess of NM500 steel plate, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the hardess of NM500 steel plate project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.
