EN 1.4441, DIN X2CrNiMo18-15-3, 316LVM, UNS S31673 is a high performance stainless medical steel 

for medical stainless steel implants.

Due to the remelting procedure ESU/ESR, this implant material offers excellent microstructural cleanliness

and high fatigue strength.

ASTM F138, Standard specification for wrought-18 Chromium-14 Nickel-2.5 Molybdenum Stainless steel bar

and wire for surgical Implants UNS S31673

ASTM F139, Standard specification for Wrought-18 Chroimium-14 Nickel-2.5 Molybdenum Stainless steel sheet

and strip for surgical Implants UNS S31673

DIN 17443, Rolled and wrought stainless steel products for surgical implants, technical delivery conditions

ISO 5832-1, specifies the characteristics of, and corresponding test methods for, wrought stainless steel for

use in the manufacture of surgical implants.

NOTE 1, The mechanical properties of a sample obtained from a finished product made of this alloy can differ from

those specified in this part of ISO 5832.

NOTE 2, The alloy described in this part of ISO 5832 corresponds to UNS S31673 referred to in

ASTM F138/ASTM F139 and to alloy code 1.4441 given in the withdrawn DIN 17443.

An optimized chemical composition guarantees high corrosion resistance, biocompatibility

and antimagnetic behavior.
