Bar and wire shall be furnished, as specified, in the hot-worked, annealed, cold -worked, or extra hard condition. This abstract is a brief summary of the referenced standard. The chemistry modifications are designed to maximize the corrosion resistance of this alloy and provide a ferrite free microstructure. Product analysis limits shall be as speci? Analysis for elements not listed in Table 3 is not required to certify compliance satm this speci?
Published information has shown no adverse effect for compositions containing up to 1. F — 03 Standard T138 Materials and Manufacture 5. The secondary premium melting step imparts improved cleanliness. Current edition approved June 10, The manufacturer shall not ship material that is outside the limits speci?
Your comments will receive careful consideration at a meeting of astj responsible technical committee, which you may attend. Quality Program Requirements However, long term clinical experience has shown an acceptable level of biological response can be expected, if the material is used in appropriate applications.
LS / LVM Surgical Stainless Steel Bar – ASTM F
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. BrinellB Hardness, max, HB Originally approved in Please contact us for more details. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Billet shall also be ultrasonically tested prior to being hot rolled and should be free of internal defects. The SI units given in parentheses are for information only. Under minimum limit not applicable for elements where only a minimum percentage is indicated. The alloy is nonmagnetic even after severe cold forming operations.
Link to Active This link will always route to the current Active version of the standard. The outcome equals considerably longer tool life, increased productivity, better chip breaking, better dimensional tolerances, superior machined surface quality, reduced scrap losses, and consistent performance which translates to a reliable production schedule. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
While most manufacturers quickly turn to material costs as a primary means of lowering their price, these short-term accommodations are not always sustainable. Mm Ksi MPa Up to 0.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Recommended crosshead speed for cold-drawn? Find out more by contacting us at General Requirements for Delivery 3.
C Typically supplied as hot-rolled astmm for forging applications. Due to the well characterized level of local biological response established by this material, it has been used as a control material in Practice F Work Item s – proposed revisions of this standard. The heat analysis shall conform to the requirements as to chemical composition specified and the material shall contain no delta ferrite, chi, or sigma phases when it is examined by metallography.
Last previous edition approved in as F — Hardness determination on cold-worked material shall be made on a product cross-section, midway between the center and surface, if cross-section size is adequate. Alternatively, a gage length corresponding to ISO may be used when agreed upon between supplier and purchaser. Fine wire shall be furnished, as specified, in the cold-drawn condition.
316LS / 316LVM Surgical Stainless Steel Bar – ASTM F138
Different tests shall be performed in order to determine the following mechanical properties of the wire and bar: Approved June 10, Advanced ladle metallurgy allows for fine adjustments of the composition, amount, size, shape and distribution of the nonmetallic inclusions normally occurring within standard stainless steel. Historical Version s – view previous versions of standard. On the other hand, types of finish available for fine wire products are cold-drawn, ground, and ground and polished.
The percentage iron content by difference g138 not required to be reported. A number in parentheses indicates the year of last reapproval.
