WebFeb 25, 2024 · Data from [9] So if the steel had 1%Mn the Mn multiplying factor would be about 1.75, and a factor for 0.5% Si would be about 1.22. Using the factors for C, Mn, and Si then, the factors are multiplied together: 0.61*1.75*1.22 = 1.3 which gives a relative, approximate value for hardenability.

WebApr 10, 2024 · Hardened steels are created by rapidly quenching the material from a high temperature. This involves a rapid transition from a state of 100% austenite to a high percentage of martensite. If the steel is more than 0.15% carbon, the martensite becomes a highly strained body-centered cubic form and is supersaturated with carbon. Websteel cools and at each isothermal step the incubation of transformation can be expressed as the ratio of cooling time for the temperature interval to the incubation period given by TTT diagram. This ratio is called the fractional nucleation time. 18
