hardox 450 steel grade for boiler applications

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our Hardox 450 steel grade steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge Hardox 450 steel grade steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

Difference between Q235 steel and Q345 steel: First, The lower limit of yield strength of Q235 steel is 235MPa, and that of Q345 steel is 345MPa. Second, Q235 steel is common carbon steel, Q345 steel is low alloy steel. They have different alloy contents. Besides, Q235 steel is for general strength application, Q345 steel is for higher strength application. Hardox 450 steel grade, Q345 steel price is higher than Q235 steel price. But Q345 steel can save materials for sake of high strength.

The main advantage of weather resistant steel plate is its weathering ability. When exposed to the atmosphere, the weather resistant steel plate will form a anti-corrosion film on the surface, and prevent further corrosion to the steel Hardox 450 steel grade. Thus the weather resistant steel plate almost needs no paint treatment, which is the important measure for carbon steel plates to avoid going rust. Therefore, the maintance cost of weather resistant steel plate is low. The weather resistant steel plate is suitable for outside structure and construction use.

The Hardox 450 steel grade stainless steel 2250 mm wide coil mill has advantages such as adapting to difficult-to-deform steel grades. The Liuzhou Iron and Steel Hot Rolling Leveler project designed and supplied by MCC South is equipped with the latest straightening and leveling process (LTP technology) developed by MCC South. The Hardox 450 steel grade performance stability, cost and various consumption indicators have reached the international advanced level.

Chemical composition of 65Mn steel: C 0.62-0.70, Si 0.17-0.37, Mn 0.90-1.20, Cr ≤ 0.25, Ni ≤ 0.30, Cu ≤ 0.25. 65Mn steel mechanical properties: tensile strength: ≥735 Mpa, yield strength: ≥430 Mpa, elongation after fracture: ≥9%, reduction of area: 30%, impact absorbed energy: no impact. Hardox 450 steel grade, 65Mn steel has high strength, high hardenability, less decarburization tendency, overheat sensitivity, easy to produce quenching cracks and temper brittleness. 65Mn steel is used for making various flat and round springs, leaf springs, spring rings, valve springs, steel wire cold coil springs, clutch springs of light trucks and cars.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel Hardox 450 steel grade products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
