Steel, Corrosion and Heat Resistant, Bars, Wire, Forgings, Tubing, and Rings 12Cr Ferrite Controlled, Annealed
|Publication Date:||1 July 2000|
This specification covers an aircraft-quality, corrosion and heat resistant steel in the form of bars, wire, forgings, mechanical tubing, flash welded rings, and stock for forging or flash welded rings.
These products have been used typically for parts requiring a combination of high room temperature tensile properties with oxidation resistance up to 1000 °F (538 °C) and where control of ferrite content is necessary, but usage is not limited to such applications.
1.2.1 Certain design and processing procedures may cause these products to become susceptible to stress-conversion cracking; ARP1110 recommends practices to minimize such conditions.
