Full Description

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 degrees F (316 degrees C), but usage is not limited to such applications.

Certain processing procedures and service conditions may cause these castings to become subject to stress-corrosion cracking. ARP1110 recommends practices to minimize such conditions.
