Martempering/Marquenching Marquenching/Martempering is a form of heat treatment applied as an interrupted quench of steels typically in a molten salt bath at a temperature right above the martensite start temperature. The purpose is to delay the cooling for a length of time to equalise the temperature throughout the piece. This will minimise distortion, cracking and residual stress. Benefits Reduced cracking due to thermal stress. Reduced residual stress in the quenched part section for parts with varying geometry, size, or weight. Application & materials Since marquenching lowers the residual thermal stress, it is used for parts with complex geometries, diverse weights, and section changes.
Marquenching is used primarily to minimise distortion and eliminate cracking. Alloy steels are generally more adaptable to marquenching.
In general, any steel part or grade of steel responding to oil quenching can be marquenched to provide similar physical properties. The grades of steel that are commonly marquenched and tempered to full hardness are: 90Mn4 / 1.1273 / AISI 1090 42CrMo4 / 1.7225 / AISI 4140 100Cr6 / 1.3505 / SAE 52100 44SMn28 / 1.0762 / SAE 1144 50CrMo4 / 1.7228 / AISI 4150 34CrNiMo6 / 1.6511 / AISI 4340 43CrNiMo6 / 1.6582 / 300M, 4340M 46Cr2/ 1.7006 / AISI 4640 41Cr4/ 1.7035 / AISI5140 50CrV4 / 1.8159 / AISI 6150 30NiCrMo2 / 1.6545 / AISI 8630 40NiCrMo2 / 1.6546 / AISI 8740 Process details Marquenched parts are tempered in the same manner as conventional quenched parts. Steel is marquenched and tempered by: • Quenching from the austenitising temperature into a hot fluid medium at a temperature usually above the martensitic range; • Holding in the quenching medium until the temperature throughout the steel is substantially uniform; • Cooling at a moderate rate to prevent large differences between the outside and the centre of the section; and • Tempering in conventional fashion.
