30Cr13 is a martensitic stainless steel known for its high strength, hardness, and wear resistance. It is commonly used in automotive, machinery, tooling, and aerospace applications.
After heat treatment, it offers excellent mechanical properties, making it suitable for parts like gears, shafts, and cutting tools. While it has moderate corrosion resistance, it performs well in less aggressive environments.
30Cr13 is ideal for parts requiring strength, abrasion resistance, and moderate corrosion resistance.

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 is obviously better than the imported ones. The carbide is small and uniform.
