AISI 316L MIM 5–20 µm is a high-quality austenitic stainless steel powder engineered for metal injection molding (MIM) applications. Its fine, spherical morphology and tightly controlled particle-size distribution ensure excellent flowability, homogeneous binder mixing, and uniform mold filling. The alloy delivers outstanding corrosion resistance, good mechanical strength, and reliable sintering behavior, enabling the production of dense, dimensionally accurate components with smooth surface finish. AISI 316L MIM parts provide long-term durability, chemical stability, and consistent performance in demanding industrial and precision-engineering applications.
