Datasheet: Stainless Steel 316LVM
Stainless Steel 316LVM
Regarded as ‘Medical Grade’, Stainless Steel 316LVM is vacuum melted to achieve the extremely high levels of purity and ‘cleanliness’ required for surgical implants. It has excellent resistance in physiological environments, to general and intergranular corrosion, to pitting and crevice corrosion. These characteristics make it ideal for both medical application and high precision electronics.
Stainless Steel 316LVM is also known as AISI 316LVM.
Available in all profile options
