Material Grade 18CrMo4
18CrMo4 is a high alloyed heat treatable steel. It is mainly used for parts of higher strength and larger dimension in the motor vehicle and internal combustions engines, such as camshafts, axles, transmission components, crankcases, differential gears, flywheels, and other components for the automotive industry. It is also used in applications requiring good wear resistance, such as mortar mixer drums, drum drive chains, conveyor chains, etc.
Due to its good heat treatment properties 18CrMo4 is used often in heavily loaded parts of machine and apparatus building. Examples are shafts with radial and axial stress, axles, gears and pins of toothed wheels. Its applications also include many parts of chemistry technique and machine construction that have to withstand strongly fluctuating stress with temperature. Examples are tree-hole tubes, intermediate plates of heat exchangers, balls of valves, nozzles and pressing elements, seals of pistons for installations of internal combustion engines and die forgings.
18CrMo4 has a very good machinability associated with its high hardenability and moderate tempering stability. It combine high strength, ductility, toughness and wear resistance after proper heat treatment. This makes it a suitable material for hot work tools, extrusion dies, cold rolled coils and strips, dies for injection moulds, ..etc. 18CrMo4 is commonly supplied in and normalized condition for a number of automotive and mechanical engineering applications.
When compared to other heat treatable steel grades such as 4130 or 4140 alloys, 18CrMo4 is known to have higher tensile strength and yield strength, combined with good formability. These properties make it an ideal choice for a wide range of applications. It can be used in the manufacture of crankshafts, camshafts, gears, and shafts, as well as a variety of components for automotive and engineering applications.
Moreover, 18CrMo4 is commonly used in the production of all kinds of parts, such as small gears, shafts, wheels and valve components. Its exceptional wear resistance makes it suitable for all kinds of roller shutters, fencing and access barriers, as well as sliding doors and conveyor systems. It is also used for various components for the agriculture and construction industry.
In conclusion, 18CrMo4 is a high alloyed heat treatable steel with good machinability, which is ideal for applications requiring good wear resistance, strength, and formability. In addition, its high yield strength, combined with its excellent tempering stability, makes it suitable for a wide range of applications in the automotive, engineering and construction industry.
