Alloy Wire International
Datasheet: Stainless Steel 316LVM
Stainless Steel 316LVM
Regarded as ‘Medical Grade’, this stainless steel 316 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.
Stainless Steel 316LVM is also known as AISI 316LVM.
Available in all profile options
