Effect of chromium and titanium on creep and relaxation of cast iron

Conclusions

• 1. Alloying of cast iron with chromium and nickel is inadvisable for parts needing high resistance to creep and relaxation at 400–500°.

• 2. For cast iron working at temperatures up to 330° the addition of chromium is desirable, since it stabilizes pearlite and hardens the cast iron.

• 3. At a concentration of ∼0.2%, titanium substantially increases the resistance of cast iron to creep and relaxation at all temperatures investigated (330, 400, 520°).
