低碳钢 (【技】含碳量 ≤0. 25% 的钢,具有强度低、塑性高、韧性高及良好的加工成型性和焊接性能,适于制造形状复杂和需要焊接的构件。普通低碳钢一般不进行热处理而直接使用。优质低碳钢或不进行热处理,或进行表面硬化处理,主要用于生产普通薄钢板、无缝钢管、焊接钢管、普通线材等;也广泛地作为渗碳钢,用于机械制造业。: ① Low-carbon steels are soft, tough steels that are easily machined and welded. 低碳钢既软又韧,易于机加工和焊接。 ②The case-carburizing process makes the surface of steel hard while its inside retains the toughness characteristic of low-carbon steel. 表面渗碳法能使钢的表面硬化,而内部仍保持低碳钢的韧性。) | |||
