standard of nm450 wear-resistance main application data

The X80M pipeline steel customized by the company for customers will be supplied to a construction machinery manufacturing enterprise for making core components of rotary drilling rigs. Based on the original production process of high-end standard of NM450 wear-resistance pipeline steel, the company formulated and optimized the process plan and production operation plan, strictly controlled the content of harmful elements in the production, optimized the rolling parameters and cooling mode, and ensured that all performance indexes of customized X80M standard of NM450 wear-resistance pipeline steel met the requirements of customers.

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.

Q345R steel (16MnR) is a low-alloy high-strength steel. It is a special plate for pressure vessels with a yield strength of 340MPa min. Q345R plate has good comprehensive mechanical properties and technological properties. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 steel (16MnR). In addition to the increased tensile strength and elongation requirements compared to Q345B steel, standard of NM450 wear-resistance, the impact toughness is also required.

As for the mechanical properties of standard of NM450 wear-resistance, ASTM A572 Gr.50, 345 Mpa is the yield point levels most closely approximating a geometric progression pattern between 36 ksi min yield point steels covered by Specification A36/A36M and 100ksi min yield point steels covered by Specification A514/A514M.

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 standard of NM450 wear-resistance 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.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products standard of NM450 wear-resistance 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.
