Q: It says that Alloy 330 is carburization resistant. What does that mean exactly?
A: Carburization is when heat hardens a metal. Carburizing is sometimes used in alloy aging processes when your goal is to harden the alloy. On the other hand unwanted carburization can occur at extreme temperatures which causes the metal to unwantedly harden and become brittle – which inturn can cause breakage. Alloy 330 bolts minimize this even at extreme temperatures to 2100°F.
