Temper Embrittlement primarily affects what materials?
2.25Cr-1Mo low alloy steel.
3Cr-1Mo (to a lesser extent).
High-strength low alloy Cr-Mo-V rotor steels.
What materials manufactured prior to 1972 may be particularly susceptible to Temper Embrittlement?
Older generation 2.25Cr-1Mo.
What materials are also susceptible to Temper Embrittlement?
Some high strength low alloy steels.
What materials are not significantly affected by temper embrittlement, but can have their toughness or high-temperature ductility altered by metallurgical changes promoted by high-temperature damage mechanisms?
C-0.5Mo alloy steel
1Cr-0.5Mo alloy steel
1.25Cr-0.5Mo alloy steel
What materials are generally more affected than today’s low-impurity base materials?
