3D Printing 420S
Description
420S is a martensitic stainless steel of the ~12% chromium type. Due to its chromium content 420S achieves high hardness. In addition, it possesses of good strength and good corrosion resistance in mild environments. Our 3D printing 420S is a nitrogen gas atomized, good flowable spherical powder for additive manufacturing. And it finds applications in cutting utensils, surgical and dental instruments, molds and multi-purpose tools.
