Webinar Overview

Several metal alloys such as stainless steel (SS), titanium (Ti), and cobalt-chromium-molybdenum (CoCrMo) have been used in various biomedical applications ranging from permanent implants and temporary fixation devices to surgical tools and cutting instruments. Among the various metallic materials used for orthopaedic devices, stainless steel alloys such as 300 series, 400 series, 17-4PH, C455, C465 are some of the most widely used for biomedical implants and surgical tools due to excellent corrosion resistance, biocompatibility, and mechanical properties. However, there is a need for next-generation stainless steel alloys with enhanced properties to meet the demanding needs of medical devices either due to developments in surgical procedures (robotic assisted and minimally invasive surgeries), production techniques (additive manufacturing, Light’s out production) or changing regulatory framework (EUMDR).

In this presentation, we will discuss the development of EUMDR compliant, Low-Cobalt variants of the commonly used stainless steel alloys along with Low-Nickel stainless steel variant of 316L (BioDur 108). We will present results on the development of Low-Stress 17-4 material with a goal to mitigate issues caused due to the presence of variable high residual-stresses in conventional feedstock to support continuous lights out manufacturing, improve productivity and reduce scrap. We will also introduce A-21 – Carpenter Technology’s latest development of a strong, tough, carburizable stainless steel for high-performance surgical instruments and cutting tools applications. We will discuss the efforts undertaken to support development and production of high strength small diameter stainless steel alloys for small, miniature medical devices for Robotic and Minimally Invasive surgeries. Towards the end, we will highlight the benefits of Carpenter’s Stainless steel powder offerings (unique chemistries, processing parameters) for additive manufacturing of next generation medical devices.
