The salt spray test and its use in ranking stainless steels
www.worldstainless.orgstainless steel is used for many applications in the Industrial, Automotive or Domestic sectors. Stainless steel is steel with a chromium content of more than 10.5%. By adding various alloying elements it is possible to create a complete range of grades, which have different physical or chemical properties. The choice of grade
MANUAL FOR SURFACE TREATMENT OF STAINLESS STEELS
www.voestalpine.com1.1. STAINLESS STEEL GRADES AND CLEANING In any application, stainless steel grades are selected on the basis of required properties (e.g. corrosion resistance), design criteria and fabrication requirements. However, there are many different iron-carbon-chromium alloys that are collectively referred to as stainless steels.
Design Guidelines for the Selection and Use of Stainless ...
nickelinstitute.orgDuplex 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 several advantages over the common austenitic stainless steels. The duplex grades are
Sandvik duplex stainless steels
www.materials.sandvikIn tube applications, for example, duplex s higher strength lends itself to thinner walls that withstand the same pressure levels as those of conventional steels. Equally important, duplex s high corrosion resistance ensures signi cantly more uptime than carbon steels and conventional stainless steels. Taking into account duplex stainless ...

An Introduction to Super-Duplex Stainless Steels
www.corrotherm.co.ukof ferrite and austenite, Duplex stainless steels are a family of grades, which range in corrosion performance depending on their alloy content. The term “Super-Duplex” was first used in the 1980’s to denote highly alloyed, high-performance Duplex steel with a pitting resistance equivalent of >40 (based on Cr% + 3.3Mo% + 16N%).
WELDING OF STAINLESS STEELS AND OTHER JOINING …
nickelinstitute.orgBy definition, stainless steels are iron-base alloys containing 10% or more chromium, which imparts to the metal the corrosion-resistant properties for which stainless steels are so highly regarded. The chromium content may be increased and other alloying elements added or adjusted to meet specific end-use or manufacturing requirements.

As with other precipitation hardening alloys, AL 17-4 Pre-cipitation Hardening Alloy is more susceptible to stress corrosion cracking at peak strength. Consequently, in applications in which chloride stress corrosion cracking is a possibility, the material should be precipitation hard-

Stainless Steels Welding Guide - Lincoln Electric
www.lincolnelectric.comSTAINLESS STEELS Austenitic stainless steels include the 200 and 300 series of which type 304 is the most common. The primary alloying additions are chromium and nickel. Ferritic stainless steels are non-hardenable Fe-Cr alloys. Types 405, 409, 430, 422 and 446 are representative of this group. Martensitic stainless steels are similar in ...
