Stainless steel chromium

Over time a large variety of materials have been used, including ivory, stainless steel, chromium—cobalt, and ceramics for the acetabular component. None proved sufficient. The implant material composition must provide a smooth surface for joint articulation, withstand hip joint stresses from normal loads, and the substance must disperse stress evenly to the cement and surrounding bone.

C) 370/656X brittleness after exposure to temperatures between about 700 to 1. OSO-F. stainless steels. chromium stainless steels, over 13% Cr and any 400 Series martensitic chromium stainless steels low in carbon content (high Cr/C ratio). complex chromium compound, possibly a chromium-phosphorus compound. chromium steels at temperatures above about 700 F (370 C) keep carbon up in martensitic chromium steels and limit Cr to 13% max.

Stainless Steels Chromium-nickel steels are suitable for service at temperatures as low as -250°C (-425°F). Type 304 is the most pop-... [Pg.45]

Chromium has taken its place among the world s useful metals, and stainless steel, chromium-plated hardware and automobile trimmings, and artistic chromium jewelry now bear witness to the importance of Vau-quelin s discovery. [Pg.279]

Chromium (0.02% lithosphere) is produced from chromite, FeCr204. Direct reduction of this compound with carbon yields ferrochrome, an iron-chromium alloy used in making stainless steel. Chromium is obtained free from iron by converting the chromite first to a soluble chromate, then to the sesquioxide CrgOg, and finally to metal ... [Pg.467]

Stainless steel Chromium, nickel and iron have been analysed. For iron, all results were very low and most of them are near detection limits or do not significantly differ from the noise (iron in the test waters). For chromium, all results were below the detection limits of the analytical methods except for one 25 igl after 1 hour s stagnation on d 637. These were both with TZW nanofiltration concentrate.

Intergranular corrosion can result from an enrichment or depletion of one of the alloying elements at the grain boundary. Stainless steels, chromium, and nickel-rich alloys are all susceptible to intergranular corrosion. [Pg.1319]

Precipitation of carbides At the grain boundaries of stainless steels, chromium reacts with carbon to precipitate chromium carbides. Carbides of Ni, molybdenum, titanium and niobium, are well-known. Chromium carbide is represented by Cr23Cg. [Pg.267]

Metal implants have become essential biomedical therapeutic tools in a variety of treatments. Metal implants are composed of a variety of metals, depending on function and location. Medical grade stainless steel, chromium-cobalt and titanium alloys are the most frequently used materials. Aluminum, chromium, cobalt, iron, manganese, molybdenum, nickel, titanium, vanadium and zirconium are the most frequent metals used for metal implants [1]. [Pg.175]
