Steel strip st. X12 30x500mm

Steel strip st. X12 30x500mm characteristics in essence:

designed for cold dies with high Cr alloying;

it has in its chemical composition carbon in the range of 2.00% - 2.20% and chromium in the range: 11.5-13.0%, which favorably influenced a number of properties of this alloy;

main advantages - it has high strength and is well calcined in depth, heat-resistant, prone to secondary hardening;

also, this metal is technologically advanced, it is easy to process by cutting and under pressure, it is polished satisfactorily.

When alloyed with Cr, special carbides are formed. This element increases the resistance of such carbides to dissolution when heated and reduces the sensitivity to overheating during operating cycles. It allows the material, when heated to 500 ° C, to maintain a high value of resistance to plastic deformation, as well as maintain a slight change in the yield strength and strength. But the resistance to surface oxidation and environments with aggressive effects is maintained up to 650 ° C.

X12 (X12MF) steel is used for the production of cold deformation dies with high abrasion resistance, especially with a rounded working surface that is not subject to strong impacts.

Popular heat treatment modes:

When annealing this alloy, the cooling rate is recommended from 40 ° C to 80 ° C per hour to 500 ° C.

The required microstructure after quenching is martensite. The quenching temperature is 970 degrees Celsius. Cooling in oil provides the required rate to obtain a given structure. It is necessary to maintain the tempering temperature at 180 ° C. Cooling the product in air provides such a crystal lattice. Vacation must be done immediately after the hardening procedure.
