Meaning and Usage
"钢铁" literally means "steel and iron," referring to the metal alloy steel. It is commonly used to talk about materials in construction, manufacturing, and industry. Beyond the literal meaning, "钢铁" is often used metaphorically to describe someone's willpower or spirit as very strong and unyielding, similar to the English expression "heart of steel."
Common Collocations
- 钢铁行业: steel industry, a major economic sector
- 钢铁般的意志: willpower like steel, describing strong determination

Usage Notes
When used metaphorically, "钢铁" usually appears in phrases like "钢铁般的" followed by a noun such as "意志" (will) or "心" (heart). This usage emphasizes toughness and resilience. In technical contexts, it refers strictly to the metal. Avoid confusing "钢铁" with just "铁" (iron), as steel is an alloy with different properties.
Register and Tone
"钢铁" is a neutral term suitable for both formal and informal contexts. The metaphorical use is common in speeches, literature, and everyday conversation to praise someone's strength of character.
