About This Item
ASTM F139 is the standard specification for wrought 18 chromium-14 nickel-2.5 molybdenum stainless steel sheet and strip used for surgical implants. It defines a technical basis for evaluating this implant-grade stainless steel in sheet and strip form, helping buyers, manufacturers, and quality teams align on material expectations. For medical device applications, that consistency matters because material selection can affect processing, performance, and compliance. ASTM F139 supports clearer procurement and more reliable product qualification.
Overview of ASTM F139
This ASTM standard focuses on wrought stainless steel sheet and strip made to the 18 chromium-14 nickel-2.5 molybdenum composition identified as UNS S31673. As a product specification, it provides a common reference for material requirements associated with surgical implant applications. ASTM F139 is typically used when a controlled stainless steel product is needed for engineering, sourcing, and quality control decisions. Its role is to help standardize expectations for material form and composition in a regulated technical setting.
Common use cases of ASTM F139
ASTM F139 is commonly referenced in the manufacture and procurement of stainless steel sheet and strip intended for surgical implants. It is useful when teams need a specification to guide material selection, incoming inspection, supplier documentation, and final product review. The standard may also support communication between medical device manufacturers and material suppliers by clarifying the expected alloy type and product form. In practice, it helps keep implant-related stainless steel purchases and production workflows consistent.
Benefits of using ASTM F139
Using ASTM F139 can improve consistency across purchasing, manufacturing, and quality assurance activities. It gives organizations a recognized specification to support compliance checks, compare supplier offerings, and reduce ambiguity in material requirements. For surgical implant applications, that can help lower risk in product evaluation and streamline technical review. ASTM F139 also provides a practical reference for documenting material conformance and maintaining a more controlled supply chain for stainless steel sheet and strip.
