The production limit boosts the NM450 steel grade price by stage

45MnB characteristics and applications: alloy structural steel has good hardenability, the critical hardenable diameter in oil reaches 17 ~ 31mm. The machinability of steel NM450 steel grade is good, the forging and heat treatment process performance is also good, the tendency of grain growth, oxidation, decarburization and heat treatment deformation is also small when heated. 45MnB steel is mainly used for gears on machine tools, spindles of drilling machines, turning shafts and cams of tractors.

With high-quality NM450 steel grade steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our NM450 steel grade steel market and improved the control of steel plate production quality.

Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing NM450 steel grade steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.

When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the NM450 steel grade, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
