冷作模具鋼是指使金屬在冷態下變形或成形所使用的模具鋼。其含碳量為1.45%～2.30%，含鉻量為11%～13%。

冷作模具鋼通常在成分上以高碳為主，以滿足高硬度和高耐磨性的需要。如果為了提高模具抗沖擊能力，需增加韌性時，可選用中碳鋼，這時可借用熱作模具鋼來代替。在冷作模具鋼中加入合金元素時，主要是為了提高淬透性和耐磨性，對于耐磨性要求高的模具，多采用加入碳化物形成元素，例如Cr、Mo、W、V等元素的多元合金鋼。

從鋼材類別考慮，冷作模具鋼多為過共析鋼和萊氏體鋼，一般屬于工具鋼范疇。

冷作模具鋼的使用性能

1)較高的耐磨性

2)較高的強度和韌性

3)較強的抗咬合性。

4)受熱軟化能力
