316LVM stainless steel or 1.4441 stainless steel (316L grade which confirms ISO 5832-1 norm) is a medical implant grade. This grade is written as 1.4441 or X2CrNiMo18-15-3 according to EN norm and it is written as UNS S31673 according to UNS norm. 316Lvm stainless steel is usually used inside the body parts.
316LVM stainless steel is a specific grade of stainless steel that is highly regarded for its suitability in medical applications. Here’s a detailed overview:
Composition and Properties:
Composition: 316LVM stands for “316 Low Carbon Vacuum Melted”. It is a modified version of grade 316 stainless steel, with additional processing to ensure very low levels of impurities.
Key Elements: It primarily consists of iron (Fe), chromium (Cr), nickel (Ni), molybdenum (Mo), and very low carbon content (C ≤ 0.03%).
Characteristics:
Corrosion Resistance: Excellent resistance to corrosion, particularly in harsh environments encountered within the human body.
Biocompatibility: Crucial for medical implants and surgical instruments, as it is biocompatible and does not react negatively with bodily tissues or fluids.
Strength: Offers good mechanical properties, including high tensile strength and toughness, necessary for implants subjected to stress.
Ease of Fabrication: This can be easily machined, welded, and formed into complex shapes, which is essential for manufacturing medical devices.
Medical Applications:
Implants: Used extensively for surgical implants such as bone plates, screws, and prosthetic components (e.g., hip implants, orthopedic rods).
Surgical Instruments: Commonly used in the manufacturing of surgical instruments due to its durability, corrosion resistance, and sterilization compatibility.
Catheters and Medical Tubing: Its smooth surface and biocompatibility make it suitable for use in catheters, guide wires, and medical tubing.
