| Step | Temperature Range | Holding Time | Process Description |
| Heating | 1150 ± 10 ºC | 20-100 minutes | Heat to the specified temperature to uniformly dissolve alloying elements |
| Cooling | 980 ± 10 ºC | 20-100 minutes | Cool in the furnace to further homogenize the steel structure |
| Forging | 1000ºC~1150ºC | Forging base temperature, final forging temperature between 780ºC ~ 900ºC | |
| Normalizing | First heating: 800 ± 10 ºC | 30-120 minutes | First heating to 800ºC,then raise to 920ºC,air cool to 200-300°c |
| Second heating: 650 ± 10ºC | 30-120 minutes | Second heating to 650ºC, then raise to 750ºC, air cool to room temperature | |
| Tempering | 220~240°C | 30-100 minutes | Tempering followed by air cooling to room temperature |
Production process
Photo1(Domestic). Carbon carbide size obviously appears big size.
Photo 2 (abroad), the carbide distribution is uneven, and the individual is large. Reason analysis: During the smelting process, the carbide can not be controlled well. In the late forging, although the forging ratio increases, it fails to make up for the defects of the smelting.
Photo3(ZhengDa=Zeicin) the modification of three technological processes of 1)EAF+LF+VD, 2) Special innovation smelting process of RS ESR, 3) transformation forging, so that it is obviously better than the imported ones. The carbide is small and uniform.
Photo 1 (domestic), the carbide individual is obviously large, and the processing will exhibit the phenomenon of detachment.
Photo 2 (abroad), The carbides are superior to domestic ones, but there are more angular carbides, and cracks and stress concentrations are easy to occur in use, leading to early failure.
Photo3(ZhengDa=Zeicin), the modification in the process of smelting and forging, the level of carbide is obviously superior to the imports.
Photo 1 (domestic), Zonal carbides are obvious, the carbide particles are obviously larger than the longitudinal ones, causing analysis: no modification of forging, just rolling directly.
Photo 2 (abroad), the distribution of carbides is not uniform, and the individual is large. Reason analysis: During the smelting process, the carbide can not be controlled well. In the late forging, although the forging ratio increases, it fails to make up for the defects of the smelting.
Photo3(ZhengDa=Zeicin) the modification of three technological processes of 1) EAF +LF+VD, 2) Special innovation smelting process of RS ESR, 3) transformation forging, so that it keeps obviously better than the imported ones. The carbide is small and uniform.

Because 9crl8MoV stainless steel has high hardness, excellent edge protection, and good corrosion resistance, it is widely used in the tool industry. It is commonly used to make various types of knives, such as folding knives, hunting knives, and kitchen knives, making it ideal for high-performance cutting tools.
Hair Scissors:
Due to the high material requirements of the barber scissors, it is necessary to have a certain sharp blade and durable cutting ability. And the addition of vanadium provides the effect of refining grains, so that the scissors maintain a certain toughness while maintaining high hardness, reducing the risk
