This specification covers a premium-quality corrosion and heat resistant steel in the form of welded tubing.<p>This tubing has been used typically for parts requiring corrosion resistance and high strength up to 800 °F (427 °C) after precipitation heat treatment, but usage is not limited to such applications.<p>Certain design and processing procedures may cause this tubing to become susceptible to stress-corrosion cracking after precipitation heat treatment; SAE ARP 1110 recommends practices to minimize such conditions.
