不锈钢的物理性能、力学性能和耐热性能不锈钢的物理性能 不锈钢和碳钢的物理性能数据对比,碳钢的密度略高于铁素体和马氏体型不锈钢,而略低于奥氏体型不锈钢;电阻率按碳钢、铁素体型、马氏体型和奥氏体型不锈钢排序递增;线膨胀系数大小的排序也类似,奥氏体型不锈钢最高而碳钢最小;碳钢、铁素体型和马氏体型不锈钢有磁性,奥氏体型不锈钢无磁性,但其冷加工硬化生成成氏体相变时将会产生磁性,可用热处理方法来消除这种马氏体组织而恢复其无磁性。 奥氏体型不锈钢与碳钢相比,具有下列特点: 1)高的电阴率,约为碳钢的5倍。 2)大的线膨胀系数,比碳钢大40%,并随着温度的升高,线膨胀系数的数值也相应地提高。 3)低的热导率,约为碳钢的1/3。 不锈钢的力学性 不论不锈钢板还是耐热钢板,奥氏体型的钢板的综合性能最好,既有足够的强度,又有极好的塑性同时硬度也不高,这也是它们被广泛采用的原因之一。奥氏体型不锈钢同绝大多数的其它金属材料相似,其抗拉强度、屈服强度和硬度,随着温度的降低而提高;塑性则随着温度降低而减小。其抗拉强度在温度15~80°C范围内增长是较为均匀的。更重要的是:随着温度的降低,其冲击韧度减少缓慢,并不存在脆性转变温度。所以不锈钢在低温时能保持足够的塑性和韧性。 不锈钢的耐热性能 耐热性能是指高温下,既有抗氧化或耐气体介质腐蚀的性能即热稳定性,同时在高温时双有足够的强度即热强性。 不锈钢国际标准标准 标准 标准名 GB 中华人民共和国国家标准(国家技术监督局) KS 韩国工业标准协会规格Korean Standard AISI 美国钢铁协会规格America Iron and Steel Institute SAE 美国汽车技术者协会规格Society of Automative Engineers ASTM 美国材料试验协会规格American Society for Testing and Material AWS 美国焊接协会规格American Welding Society ASME 美国机械技术者协会规格American Society of Mechanical Engineers BS 英国标准规格British Standard DIN 德国标准规格Deutsch Industria Normen CAS 加拿大标准规格Canadian Standard Associatoin API 美国石油协会规格American Petroleum Association KR 韩国船舶协会规格Korean Resister of Shipping NK 日本省事协会规格Hihon Kanji Koki LR 英国船舶协会规格Llouds Register of Shipping
