Product Description:
316LVM is a variant of 316L stainless steel, known for its low carbon content and its enhanced vacuum-melted structure. The “VM” in 316LVM stands for “vacuum melting,” which is a special process that improves the purity and overall quality of the steel. The vacuum melting process reduces the presence of impurities such as sulfur and phosphorus, making 316LVM more suitable for demanding applications like medical devices, surgical implants, and aerospace components. This high-performance stainless steel offers superior corrosion resistance, strength, and biocompatibility compared to standard 316L, making it ideal for critical applications where reliability and longevity are essential.
Features:
- Excellent Corrosion Resistance: 316LVM has excellent resistance to corrosion in aggressive environments, particularly in chloride-rich and marine environments.
- Low Carbon Content: The low carbon content (less than 0.03%) minimizes the risk of carbide precipitation and enhances resistance to intergranular corrosion, particularly after welding.
- Vacuum-Melted Structure: The vacuum melting process improves the purity of the alloy and reduces the presence of harmful impurities, ensuring a high-quality material with superior mechanical properties.
- High Strength and Toughness: 316LVM maintains good mechanical properties at both room temperature and elevated temperatures.
- Biocompatibility: Because of its excellent purity and resistance to corrosion, 316LVM is widely used in medical applications, including implants, prosthetics, and surgical instruments.
- Non-Magnetic: Like most austenitic stainless steels, 316LVM is non-magnetic in the annealed condition, making it suitable for applications where magnetic properties are not desirable.
- Enhanced Fatigue Resistance: The vacuum-melted steel provides improved resistance to fatigue and stress-corrosion cracking, making it ideal for high-stress environments.
