WHAT IS 4140 STEEL 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components. For example, axles, shafts, bolts, gears, and other applications. Similar to alloy grade AISI 4130 chrome moly alloy steel but with slightly higher carbon content. The higher carbon content of 4140 [...]

1, carbon tool steel The steel dubbed "T", so as not to be mixed with other steel types. The steel carbon content in the digital representation, to a few thousandths of the average carbon content of the said. For example, "T8" means that the average carbon content is 0.8%. The manganese content [...]
