27SiMn,合金結(jié)構(gòu)鋼。
【主要特性】 這種鋼的性能優(yōu)于30Mn2鋼,淬透性較高,在水中臨界淬透直徑達(dá)8~22mm,可切削性良好,冷變形塑性及焊接性中等;另外鋼在熱處理時(shí)韌性減低不多,但卻有相當(dāng)高的強(qiáng)度和耐磨性,特別是水淬時(shí)仍有較高的韌性;但是此鋼對(duì)白點(diǎn)敏感性大,熱處理時(shí)有回火脆性傾向及過熱敏感性。
【應(yīng)用舉例】 這種鋼主要在調(diào)質(zhì)狀態(tài)下使用,用于制造要求高韌性和耐磨性的熱沖壓件;也可在正火或熱軋供應(yīng)狀態(tài)下使用,如拖拉機(jī)的履帶銷等。
