← HistoryWhich consequence results from elevated manganese content during crucible steel production using ancient Chinese methods?
A)Increased oxidation during high-temperature processing
B)Enhanced precipitation hardening in final product
C)Decreased hot shortness during forging✓
D)Increased decarburization rate during smelting
💡 Explanation
Decreased hot shortness results from manganese scavenging of sulfur impurities via sulfide formation. This forms high melting point inclusions instead of iron sulfide at grain boundaries causing brittleness, therefore, forging workability raises, rather than other impacts.
