使焊接性能變壞。但鋼中含有少量Ti和V, 可改善鋼的焊接性能。合金元素對(duì)鋼切削性能的影響切削性能與鋼的硬度密切相關(guān), 鋼是適合于切削加工的硬度范圍為170HB~230HB。一般合金鋼的切削性能比碳鋼差。但適當(dāng)加入S、P、Pb等元素可以極大改善鋼的切削性能。合金元素對(duì)鋼熱處理工藝性能的影響熱處理工藝性能反映鋼熱處理的難易程度和熱處理產(chǎn)生缺陷的傾向。主要包括淬透性、過熱敏感性、回火脆化傾向和氧化脫碳傾向等。合金鋼的淬透性高, 淬火時(shí)可以采用比較緩慢的冷卻方法,可減少工件的變形和開裂傾向。加入錳、硅會(huì)增大鋼的過熱敏感性。合金鋁板按熱處理可否強(qiáng)化可分為可熱處理強(qiáng)化合金鋁板和不可熱處理強(qiáng)化合金鋁板。新余40cr合金板總代理</p><p
