Corrosion resistance is the ability to prevent environmental deterioration by chemical or electro chemical reactionDesirable characteristics of corrosion resistant alloys, therefore, include high resistance to overall reactions within the specific environment.
Aluminum is corrosion resistant because when its surface is exposed to oxygen, it forms an aluminum oxide layer on the aluminum's surfaceThe aluminum oxide is actually more durable than the aluminum itself, thus protecting the remaining aluminumCompare this to iron oxide, or rust, which flakes off and allows more iron oxide to form.
Breaking Down Corrosion Resistant MetalsSome metals and metal alloys are more corrosion resistant than others, of courseWith each kind of metal, there are different grades (sometimes hundreds!) with varying corrosion resistanceThe following rankings, from least to most resistant, attempts to delve into these differences in grades a little
Corrosion prevention in a specific environment is usually carried out using a corrosion resistant material, or at least one with an exceptional lifetimeThere are several methods for protection against corrosion that are based on electrochemical principles.
Corrosion resistant alloys (CRAs) The term corrosion resistant alloy (CRA) is commonly used to cover all metals that are, to some degree, capable of resisting corrosion as compared with carbon steelThis resistivity to corrosion is not universal as it varies to a large degree on the specific corrosion environment and depends on the alloying
A corrosion resistant alloy (CRA) is an alloy consisting of metals such as When combined, such metals can promote corrosion resistance more than other components like carbon steelThis type of alloy offers reliable protection from corrosion, eradicating the need for expensive maintenance and repair.
Corrosion is a process in which a material is oxidized by substances in the environment that cause the material to lose electronsCorrosion resistance is the capacity to hold the binding energy of a metal and withstand the deterioration and chemical breakdown that would otherwise occur when the material is exposed to such an environment.
FM Approved as corrosion proofing for use in corrosive environments and cULus Listed as corrosion resistantAesthetically pleasing and suitable for decorative applicationsAvailable on a wide variety of Viking sprinklersPolytetrafluoroethylene (PTFE) is known by the common brand name Teflon, which is a
Corrosionresistant steel sheet products that have been prepainted, including with lacquers or varnishes, or permanently coated in plastic Stainless steel is a generic term for a type of alloy that belongs to the corrosion resistant family of alloys that contain or more chromium by mass.
A corrosion resistant sprinkler can be designed with corrosion resistant materials or, as is common, have a corrosion resistant coating, such as wax or lead, applied to itThe manufacturer can only apply a corrosion resistant coating except as permitted for the repair of a damaged coating if the damage occurred during installation.
