不锈钢具有抵抗大气氧化的能力——即不锈性,同时也具有在含酸、碱、盐的介质中乃腐蚀的能力——即耐蚀性。但其抗腐蚀能力的大小是随其钢质本身化学组成、加互状态、使用条件及环境介质类型而改变的。如304材质的不锈钢铸件,在干燥清洁的大气中,有绝对优良检查井钢模具 隔离墩模具 隔离墩钢模具 流水槽模具 U型槽模具 螺杆启闭机 卷扬式启闭机 铜雕佛像 的抗锈蚀能力,但将它移到海滨地区,在含有大量盐份的海雾中,很快就会生锈了;而316材质则表现良好。因此,不是任何一种不锈钢,在任何环境下都能耐腐蚀, 不生锈的。
Stainless steel has the ability to resist atmospheric oxidation, that is, it is not rusty, but also has the ability to corrode in the medium containing acid, alkali and salt, that is, corrosion resistance. However, the corrosion resistance of the steel varies with its chemical composition, additive state, service condition and environmental medium type. For example, 304 stainless steel casting has absolutely excellent corrosion resistance in dry and clean atmosphere, but if it is moved to the seaside area, it will rust quickly in the sea fog containing a lot of salt, while 316 material performs well. Therefore, not any kind of stainless steel, in any environment can be resistant to corrosion, rust.
