It's characterized by good strength, hardenability and toughness, and it has high creep strength and long lasting strength under the high temperature.
It's used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clamps that are heavily loaded. It can also be used for drill pipe joints and fishing tools for oil deep wells below 2000m.
For anneal, the hardness is less than 217HB.
For Q+T, the hardness is 28-32HRC.
