To improve mechanical properties, especially elongation, of as-cast medical grade 316L stainless steel, niobium (Nb) was introduced into the alloys, followed by solution heat treatment. Niobium is non-reactive to acids and moisture at room temperatures but reacts with acids at elevated temperatures. The physical and chemical properties of niobium oxides, including the acid properties, depend on their structure 1,2,4,6. Chlorine acts on niobium above 200°C. In addition, it has corrosion resistance, superconducting properties, and can form a non-conductive oxide layer. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, targets for thin film deposition, and pellets for chemical . The metal starts to oxidize in air at 200°C, and when processed at even moderate temperatures must be placed in a protective atmosphere.

Niobium is a soft, grey, ductile transition metal, often found in the minerals pyrochlore (the main commercial source for niobium) and columbite. In air an oxide layer forms whose color depends on its thickness. Although niobium exhibits a high melting point (2468°C), it has a lower density than other refractory metals. Niobium Properties. In nature, it is often found along with pyrochlore mineral while its processed form is used in the manufacture of high-grade structural steel and super-alloys. Niobium added to steel refines remarkably the cast structure and austenite structure of steel. Thus, it follows that Corrosion resistance is the crucial requirement for any kind of equipment designed for the chemical and pharmaceutical industry. Electrical properties. 37. Alloying was performed using a 250 kg air induction melting furnace with duplex raw materials and ferronickel.
