Chetan Steel, based in Delhi, India, is a prominent steel manufacturer and supplier of top-class steel materials that serve a variety of industrial requirements. It is an advanced materials specialist providing HB 400 Sheet and Plates with excellent hardness, wear properties, and long durability. Chetan Steel’s plates are the best suited for use where abrasion resistance needs to be exceptional, such as in the mining, construction, and heavy equipment industries. With a dedication to quality, accuracy, and customer satisfaction, Chetan Steel provides creative solutions that address the most challenging engineering needs globally.
HB 400 Sheets and Plates consist of abrasion-resistant steel with a nominal hardness of 400 HBW. Their chemical composition generally consists of carbon, manganese, chromium, and boron, which imparts high wear resistance and strength. These plates have high tensile strength, impact toughness, and high elongation, and thus are apt for critical applications. Benefits are increased life of service, less maintenance, and better operation under abrasive conditions like mining, construction, and heavy equipment, with cost-effectiveness and operating reliability.

HB 400 sheets and plates are also commonly applied to industries that demand high wear and tear resistance as well as strength. Typical applications are in earthmoving equipment, mining machinery, and construction machines, where the plates endure abrasive environments. They are best for fabricating dump liners, truck bodies, hoppers, conveyor systems, and chutes. HB 400 plates are also used in the industrial environment for wear parts and screens in cement plants, and crushers. Their elevated hardness and toughness provide long life in service, minimizing maintenance and downtime in extreme conditions. They also find applications in agricultural machinery for better performance.
