UGIPURE® 4472 Solution Annealed
UGIPURE® 4472 Solution Annealed introduction
UGIPURE® 4472 is a nitrogen alloyed austenitic stainless steel with high corrosion resistance. Remelted by ESR process, this grade is perfectly biocompatible with human tissus and is non magnetic. Due to it’s chemical analysis, UGIPURE® 4472 shows a very high ability to cold drawing and so, it can achieve higher mechanical properties than 1.4441 (UNS S31673). This grade is usually used for high performance surgical implants, like thin bones screws, high mobility hip prosthesis, etc.
