MFR1.2311Pre-hardenedThe strength of low-sulfur mold steel can be adjusted by heat treatment, such as engraving by spark etching or photochemical processing, or if high polishability is required, it is more preferable and can be used for manufacturing Plastic molds below 400MM.
MFRS1.2312Pre-hardenedSpecial steel with particularly high machinability, suitable for die sleeves of die-casting machines, whose strength can be adjusted by heat treatment.
MFRx51.2738Pre-hardenedGood machinability and polishability, and suitable for sunburning. Because the nickel content is increased by about 1%, it has good through hardenability. The size mold, the maximum thickness is greater than 1500MM, suitable for automobile bumpers, dashboards.
MFRx5 Sonder1.2738.02Pre-hardenedEspecially suitable for large parts, the maximum thickness is greater than 1500MM, good polishability, good weldability, and can be nitridable, the hardness is very uniform from the surface to the center part.
MFRx5 Sonder(HQ)1.2738.02 VARPre-hardenedThe VAR (vacuum arc remelting) version of MFRx5 Sonder (HQ) has extremely high purity and uniformity, and has excellent performance in polishing and sun texture.
MS40 ESR1.2743.01 ESRPre-hardenedIt is used for high-hardness mass production of precision molds. The mirror surface requires plastic molds. Because of the low carbon content and good welding performance, it is not suitable for making large-scale molds with thickness other than 400mm.
RABW1.2767Pre-hardenedHigh wear resistance and toughness, suitable for plastic molds with high wear performance, thermosetting plastics.
RGS4 Sonder1.2711 AnnealingThe chromium-nickel-molybdenum alloy die steel with particularly high high-temperature strength and toughness is suitable for molds with high mechanical and thermal requirements.
RGS41.2714Pre-hardenedThe load-resistant die steel with increased hardening depth and high wear resistance at high temperature is especially suitable for processing hard steel and fixtures of forging machine tools, and all sizes of upper and lower dies Molds and all types of cavities.
DSM8Patented production technology AnnealingThrough special smelting, the mirror surface has good polishability, rust resistance, and toughness, it has certain rust resistance.
