V-Gin1, Gin2, and V-Gin3B are called semi-stainless steels, and they have the features of both carbon steel and stainless steel.
By adding chromium (Cr) and molybdenum (Mo), they have far better corrosion resistance and heat resistance than carbon steel, and can be quenched by air cooling like stainless steel. The microstructure contains dispersed primary carbides that contribute to wear resistance. In addition, secondary carbides, which contribute to strengthening the matrix through quenching, are evenly dispersed. While possessing the features of stainless steel as described above, it has good grindability similar to carbon steel.
In addition, molybdenum (Mo) improves high-temperature strength and softening resistance, and vanadium (V) refines the matrix.
This material clad with soft stainless steel using V-Gin1, Gin2, or V-Gin3B as the core material is widely used as "Stainless Chromax".
