1. Introduction: What Is 420 Powder and Why It Matters in PM
420 powder refers to a type of stainless steel powder, specifically martensitic stainless steel, used in powder metallurgy (PM) applications that require high hardness and moderate corrosion resistance. This grade is a popular choice for manufacturing wear-resistant components, surgical instruments, and industrial parts via sintering or additive manufacturing processes.
In the context of powder metallurgy, 420 stainless steel powder is typically produced using either water atomization or gas atomization methods, making it suitable for a range of fabrication technologies, including metal injection molding (MIM) and press-and-sinter techniques.
