What are the general materials for tractors and shaft gears and shafts?
42CrMo steel is ultra-high strength steel, with high strength and toughness, hardenability is also good, no obvious temper brittleness, quenching and tempering treatment has a higher fatigue limit and anti-impact ability, low temperature impact toughness is good.
Third, the axis of the general use of materials, widely used is high-quality carbon structural steel, such as the application of 45 steel is more extensive, 45 steel quenched and tempered with good overall mechanical properties, of course, some unimportant shaft, from the cost
First, the tractor with a larger cross-sectional area of the important gear, such as the active bevel gear and the requirements of the heart of the high strength of the carburizing gear.
Second, 42CrMo is alloy steel, for the harsh conditions of the shaft and structural parts, gear shaft generally use this material.
