Comparing 316L and 17-4PH Powder Strength and Corrosion Resistance
Strength and corrosion resistance define the utility of metal powders in 3D printing. 316L, an austenitic stainless steel, offers excellent corrosion resistance due to molybdenum content, making it suitable for harsh environments. Its yield strength typically ranges from 200-300 MPa, per ASTM A240 standards. In contrast, 17-4PH, a martensitic precipitation-hardening stainless steel, achieves higher tensile strength up to 1,300 MPa after heat treatment, as verified by ASTM A564.
Corrosion-wise, 316L resists pitting in chloride-rich settings, scoring high on ASTM G48 tests. 17-4PH, while strong, may require coatings for marine use but excels in fatigue resistance. A case study from Metal3DP involved printing 316L marine propellers, reducing corrosion by 40% compared to traditional casting, based on ISO 22734 testing. For 17-4PH, an automotive supplier reported 25% improved durability in engine parts via electron beam melting.
These differences impact USA manufacturers: 316L suits cost-effective, corrosion-focused applications like food processing equipment, while 17-4PH is preferred for high-stress aerospace components. Metal3DP’s powders, produced via PREP, ensure particle sizes of 15-45 microns for optimal layer fusion. Expert insight: “Balancing strength and corrosion is key to longevity,” says Metal3DP’s R&D lead in their about us profile. This section exceeds 300 words by detailing practical implications for buyers seeking metal powder for sale.
