The company is also developing the materials with new functions by combination of manufacturing technologies of alloy designing, heat treatment and so on. Development Case High-strength gear steel The company is developing steel materials and method of construction which can contribute to manufacturing high function gear parts that require high durability. The steel for vacuum carburizing (DEG series) can realize about double strength against fatigue by combination with shot-ball peening technology compared with the conventional materials. CVT pulley case-hardening steel In recent years low-fuel consumption automobiles have been equipped with continuously variable transmissions (CVT). CVT pulleys are coupled to form a pair, and by adjusting their position the pulleys transmit the rotational speed from the engine to drive the vehicle. Daido has developed pulley materials that are capable of withstanding high pressures and resisting wear. Microalloyed steel for high-strength connecting rods We developed our connecting rod microalloyed steel to offer superior strength and manufacturing as well as excellent fracture splitting performance. The result is a product that contributes to reduced engine size and weight. Pb free-cutting steel for high strength crank and connecting rod A free-cutting steel that contains no lead, an environmentally harmful material. We developed this free-cutting steel to be environmentally friendly yet offer the same machinability as free-cutting steels made with lead. Example of the application：Crankshaft, connecting rod, hub Dvelopment Theme Drive-train Steel for transmission, gear Steel for axle shaft, constant-velocity joint Steel for differential gear Heat treatment technology and surface modification technology of carburizing, nitriding, high-frequency quenching, shot-peening Engine, Suspension Steel for crankshaft, connecting rod Spring steel for suspension spring, torsion bar Bearing steel Technology for improving machinability high-strength (development free-cutting technology) R & D Activities Automotive Steel Research Advanced Materials Research Electromagnetic Materials Research Process Technology Research Business Development TOP R & D Activities Automotive Steel Research About DAIDO STEEL Products R&D Investor Relations Sustainability Sustainability --> Students --> Contact Us Quote Site Map Privacy Policy 電子公告 --> Terms of Use Japanese Chinese Copyright©1996-2024 Daido Steel Co., Ltd. search CLOSE
