AISI 316LVM Stainless Steel Chemical Composition, Grades, Tables and Online Pdf

AISI 316LVM refers to the austenitic stainless steel alloy that is characterized by excellent corrosion resistance and biocompatibility, which are the main properties needed for its application in relevant medical purposes. The chemical structure of its composition concentrates on iron besides chromium, nickel, molybdenum and the tiny portion of other ones. 316LVM, a special kind of steels which is also known as "l" for low carbon, has a better weldability and reduces the chance to sensitivity of 316LVM steels. This alloy grade is very well-known for its great mechanical characteristics, including high strength tensile and good formation. Produced in different forms like wire, bar, and tubing, AISI 316LVM is indeed a popular choice among medical implants, surgical instruments, and pharmaceutical equipment due to its special properties. Its detailed chemical formulation as well as the grades and attributes can be found in tables, charts and documents (PDF format) given as reference and technical sources by the manufacturers for the customer guidance.

AISI 316LVM Austenitic Stainless Steel Chemical Composition And Grade Table

AISI 316LVM is an austenitic stainless steel with exceptional properties against chemically, therefore it is the most suitable choice for medical implants and surgical devices. Its chemical formula mainly consists of metallic iron (Fe), chromium (Cr), nickel (Ni), molybdenum (Mo) and a low carbon steadiness. Therefore, this type of steel structure mainly comprises of about 17-19% chromium, 12-15% nickel, 2-3% molybdenum, and less than 0.03% carbon. Through this design, high resistance to corrosion is achieved, especially when dealing with corrosive environments as in the medical applications. Besides, its grade designation is its vacuum arc remelt capability (VM).

The Advantages and Disadvantages of AISI 316lvm Austenitic Stainless Steel

    Advantages:

  • Biocompatibility: AISI 316LVM is used commonly in medical implants based on their compatibility with the body and causing little or no reactions.

  • Corrosion Resistance: It has relatively low surface area which makes it have a high resistance to corrosion to support long term implantation in bloodstream, and other body fluids and tissues.

  • Sterilization Compatibility: AISI 316LVM does not degrade significantly when exposed to different sterilization processes like autoclaving, gamma irradiation, and ethylene oxide treatment.

  • High Strength: The combination methacrylates as a constituent gives it good mechanical strength and toughness that ensures that the produce such as implants and surgical instruments manufactured is durable and reliable.

  • Formability: AISI 316LVM is relatively ductile and highly machinable to enable the creation of different geometrical prearranged shapes of medical equipment.

    Disadvantages:

  • Cost: The precise processing and inherent high purity needs of AISI 316LVM could lead to its higher cost of production than other grades of stainless steel.

  • Machinability: AISI 316LVM exhibits reasonable machinability, but this material is, in fact, rather hard and strong, so it can be difficult to machine using standard tools and methods.

  • Sensitivity to Surface Contamination: Contamination on the surface during manufacturing can significantly affect the corrosion protection and biocompatibility of AISI 316LVM, for which proper manufacturing control is critical.

  • Limited Availability: AISI 316LVM is not as common as other stainless steel grades, which can result in longer delivery times or higher stock cost.

  • Potential for Sensitization: In some cases, AISI 316LVM maybe susceptible to sensitized condition and therefore undergo intergranular corrosion which affects its performance in corrosion areas.
