Stainless Steel Used For Medical Purposes

medical grade stainless steel

Take for example the surgical implements required for the dentistry sub-sector of the health services industry. One form of medical grade stainless steel comes in the form of an electro slag that is re-melted. Another medical grade stainless steel strip that will be re-melted is that of a vacuum arc. The implant version of these materials is of low carbon, high nickel and molybdenum. Secondary premium melting instituted helps to improve the metal’s micro-cleaning capabilities. 

This is important in the area of making dental implants. Chemistry modifications are designed enhance corrosion resistance. The increased inclusion of nickel helps to avoid the possibility of material becoming magnetic in spite of cold working. Needless to say, commercial grade varieties of stainless steel are always going to be required and available. But the chemical composition thereof differs from that required for dental implants.

And yet it can still be electro-slag re-melted and/or vacuum arc re-melted. The list of commercial applications for which stainless steel will be considered is endless. But just for a taster, here are a few examples; aircraft fittings, chemical processing equipment, jet engine parts, nuclear reactor components, oil field valve parts and paper mill equipment. Hardening martensitic stainless steel, on the other hand, will be utilized in the industrial applications of pump shafts, oil paths and mechanical seals.

These applications need to be indicative of high strength but can enjoy modest levels of corrosion resistance. Strength and toughness is achieved through heat treatment processes. Custom prepared stainless steel should be a preferred choice amongst a majority of manufacturers. They are able to provide their users with good corrosion resistance created by atmospheric environments. Just a one-step aging treatment turns the steel into a high yielding, tough piece of material with good ductility.
