What is a Corrosion-Resistant Alloy (CRA)? - Definition ...
A corrosion-resistant alloy (CRA) is an alloy consisting of metals such as: Chrome; Stainless steel; Cobalt; Nickel; Iron; Titanium; Molybdenum; When combined, such metals can promote corrosion resistance more than other components like carbon steel.
Their corrosion resistance is achieved by the formation of a complex surface film which develops by an interaction with the seawater itself, thereby protecting the metal below it. General corrosion rates for 90-10 and 70-30 Cu-Ni alloys in seawater range between 0.025 and 0.0025 mm/yr.
Corrosion Resistant Alloys provide essential corrosion resistance to components which are exposed to environments associated with oil and gas production. ... Other corrosive chemicals to which the alloy has resistance are oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many ...
Low alloy version of NITRONIC 60, primarily used for abrasion resistance, or corrosion abrasion requirements. Corrosion and abrasion resistant, tough and durable, NITRONIC 30 is the stainless steel for your abrasive needs.
Corrosion Resistant Steel. The best corrosion resistant steels in the world find their way into countless applications, from defense to aerospace, turbines and more. Acidic degradation can be easily staved off by the addition of chromium, which not only strengthens the alloy, but creates a passive oxide layer that essentially seals in the metal.
Copper Nickel: Resistance to Corrosion and Biofouling
The corrosion resistance of weld deposits made by approved weld consumables and of the adjacent, heat affected zone in these alloys does not pose a problem, as may be the case in some other alloy systems.

CORROSION RESISTANCE OF ALUMINIUM ABSTRACT Aluminium and its alloys have excellent resistance to corrosion. It does corrode under some conditions. It is preferable to avoid corrosion through appropriate alloy choice and geometric design. Corrosion is a function of the operating environment, alloy and design.
Corrosion resistance of Incoloy alloy 825 in sulfuric acid
The corrosion rate of Incoloy alloy 825 is independent of particular heat of the alloy or whether the corrosion analyses were conducted in technical grade. Therefore subsequent tests were performed in technical grade. The corrosion rate was based on condenser type utilized for the test apparatus.
The corrosion resistance of iron-chromium alloys was first recognized in 1821 by French metallurgist Pierre Berthier, ... England, while seeking a corrosion-resistant alloy for gun barrels, discovered and subsequently industrialized a martensitic stainless steel alloy.Corrosion resistance·

Corrosion Resistance - an overview | ScienceDirect Topics
G.-L. Song, in Corrosion Prevention of Magnesium Alloys, 2013 1.4.2 Compatibility with other properties. Corrosion resistance is only one of the important properties of Mg alloys. It is quite common to find designers, engineers or users are more concerned about the mechanical performance of a Mg alloy rather than corrosion performance.
Nickel and nickel-base alloys have very good resistance to atmospheric corrosion. Corrosion rates are typically less than 0,0025 mm/yr, with varying degrees of surface discoloration depending on the alloy.
