Properties of a newly developed stainless maraging steel for use in medical and dental instruments

$15.00

Maraging steels were developed in the late 1950’s at the Internatinal Nickel Company for applications requiring ultrahigh strength in combination with good fracture toughness. This family of materials includes low-carbon martensitic steels, which initially contained 18 to 25 percent nickel and substitutional elements such as cobalt, molybdenum and titanium. However, among modern maraging steels a large number of modified versions exist in which the nickel content has been reduced. The term maraging is coined from a combination of martensite and age-hardening.
