Steel, Corrosion Resistant, Investment Castings 16Cr - 4.1Ni - 0.28Cb - 3.2Cu Homogenization and Solution Heat Treated or Homogenization, Solution, and Precipitation Heat Treated
|Publication Date:||1 August 2001|
This specification covers a corrosion resistant steel in the form of investment castings.
These castings have been used typically for parts requiring good corrosion resistance and strength up to 600°F (316°C), but usage is not limited to such applications (See 8.3).
Certain processing procedures and service conditions may cause these castings to become subject to stress-corrosion cracking; ARP1110 recommends practices to minimize such conditions. Where stress-corrosion is considered to be a factor, precipitation heat treatment should be performed at a temperature not lower than 1000°F (538°C).
