Difficulty: EasyStriking Tools

Striking the faces of two hardened steel hammers directly against each other is an acceptable shop technique to increase driving force when freeing a seized component.

Answer: Answer

Answer

False
The statement is false because hammer striking faces are tempered to a high level of hardness. Striking two hardened faces together creates a severe risk of brittle chipping, which can send sharp metal fragments flying into the workspace.

Step-by-Step Solution

1
Identify the metallurgical properties of hammer striking faces.
Striking faces are induction-hardened or heat-treated to resist mushrooming and denting during standard striking tasks.
Hardened tool steel gains wear resistance at the cost of ductility, making it brittle under steel-on-steel shock loading.
2
Assess the risk of impacting two hardened steel striking faces together.
The collision between two hard, brittle surfaces creates high localized stress that causes spalling, chipping, and flying metal shards.
Shop safety standards strictly prohibit striking one hardened hammer face against another to prevent severe eye and body injuries.
