These steels are known as TRIP steels because the retained austenite transforms to martensite at high strains, resulting in an excellent work hardenability
persisting over a large amount of strain [8, 9].
The 34CrNiMo6 steel is one kind of heat-treated low-alloy engineering steel with high strength and hardenability
, which contains nickel, chromium, and molybdenum .
The Cr-Mo series steels are widely used because of their excellent properties by reasonable heat treatment process, such as favorable hardenability
and shock absorption, less tendency of temper brittleness, and good corrosion resistance [1,2].
Nickel was used for improving austenite stability and for better hardenability
. Transformation temperatures were calculated by means of the JMatPro software .
For these tests, the fatigue performance of two types of bearing steels with different heat treatments were analyzed: 100Cr6, typically applied in wheel bearing applications requiring small and medium size rolling elements, and 100CrMnSi6-4, typically required in large rolling elements manufacturing due to its hardenability
The company says by visiting steelnavigator.ovako.com, users can search from a growing online database of more than 200 steels by standard, mechanical properties, weldability and hardenability
, chemical composition and more.
Steel for carburizing, as represented by SCM420 in the JIS standard, has high hardenability
. After hot rolling and cooling, the microstructure becomes ferrite and pearlite containing bainite.
On the effect of manganese on grain size stability and hardenability
in ultrafine-grained ferrite/martensite dual-phase steels, Metallurgical & Materials Transactions A 43A: 37-46.
This provides toughness and corrosion, hardenability
and wear resistant.
DP1000HY steel incorporates carbon and manganese to increase its strength and hardenability
. It is available in a range of dimensions, in thicknesses of up to 2mm and widths of up to 1,400mm.
