Applications of Zirconium. One of the major applications of Zirconium is as a corrosion-resistant material of construction for the chemical processing industry. Zirconium exhibits excellent resistance to corrosive attack in most organic and inorganic acids, salt solutions, strong alkalis, and some molten salts.
The archetypal duplex alloys contain 22-23Cr, 4.5-6.5Ni and 3-3.5Mo wt%, representing some 80% of all duplex stainless steel use. Detailed compositions are given in Table 4. A significant application is in the production of tubing in corrosive oil and gas wells; such tubes have been installed particularly in
unalloyed steel turns to rust. When ordinary steel is rubbed off on stainless steel, the material which is transferred to the stainless steel is generally referred to as "free iron." This kind of "contamina-tion" of stainless steel is also known by the misnomer of
Duplex Stainless Steel fasteners are widely used for critical applications that demands a combination of excellent corrosion resistance and high strength. The material has very high strength, even in annealed condition, and is therefore difficult to cold form.

stainless steel. But there is no study on turning of Super Duplex 2507 stainless steel with PVD coated carbide TiAIN Nano-multilayer so far in the literature. Hence, an attempt has been made in this work to investigate the machinability of dry turning operations of
Austenitic stainless steels, and more recently duplex stainless steels, have shown excellent long-term performance; guidelines for their use can be found in standards such as NACE MR0175/ISO 15156. Chloride stress-corrosion cracking has been studied for years; many people are familiar with the 'Copson Curve', derived from testing in aggressive boiling magnesium chloride.

DESIGN GUIDELINES FOR THE SELECTION AND USE OF STAINLESS STEEL
Duplex stainless steels (Table 5) have an annealed structure which is typically about equal parts of austenite and ferrite. Although not formally defined, it is gener-ally accepted that the lesser phase will be at least 30% by volume. Duplex stainless steels offer

2019/6/12'Hyper' duplex stainless steels have gone the other way, with chromium contents of 27-29% compared with the 22% of duplex and 25% of super duplex, leading to an increase in corrosion resistance. In this instance, they are proving difficult to manufacture in the wrought form (bars, plates) and are limited to seamless tubes.

Stainless steels are only one segment of the steel spectrum, but they serve a multitude of applications from brightly polished consumer pro- ducts to machinery and equipment for tough industrial environments.
Duplex stainless steels have a ferritic-austenitic microstructure, in roughly equal proportions 50% ferrite and 50% austenite. Duplex combines many of the attractive properties of ferritic and austenitic stainless steels into one. They are designed to provide better corrosion resistance, in particular to stress corrosion and pitting corrosion.
