B536钢板【采购助手】【330合金钢】高强耐热合金钢
高温合金是指以铁镍钴为基,能在600℃以上的高温及一定应力作用下长期工作的一类金属材料;并具有较高的高温强度,良好的抗氧化和抗腐蚀性能,良好的疲劳性能、断裂韧性等综合性能。高温合金为单一奥氏体组织,在各种温度下具有良好的组织稳定性和使用可靠性。
基于上述性能特点,且高温合金的合金化程度较高,又被称为“X合金”,是广泛应用于宇航、石油、核能、化工、X、舰船的一种重要材料。按基体元素来分,高温合金又分为铁基、镍基、钴基等高温合金。铁基高温合金使用温度一般只能达到750~780℃,对于在更高温度下使用的耐热部件,则采用镍基和难熔金属为基的合金。镍基高温合金在整个高温合金X域占有特殊重要的地位,它广泛地用来制造发动机、各种工业燃气轮机X热端部件。若以150MPA-100H持久强度为标准,而目前镍合金所能承受的X高温度〉1100℃,而镍合金约为950℃,铁基的合金〈850℃,即镍基合金相应地高出150℃至250℃左右。所以人们称镍合金为发动机的心脏。目前,在X的发动机上,镍合金已占总重量的一半,不仅涡轮叶片及燃烧室,而且涡轮盘甚至后几X压气机叶片也开始使用镍合金。与铁合金相比,镍合金的X点是:工作温度较高,组织稳定、有害相少及抗氧化搞腐蚀能力大。与钴合金相比,镍合金能在较高温度与应力下工作,尤其是在动叶片场合。
