3.1 Definition of Term Specific to This Standard—It is necessary to define which of the veral commonly ud definitions of the term passivation will be ud in this specification. (See Discussion.)
3.1 本标准的术语定义——在本技术规范将经常使用到的几个术语“钝化”的定义有必要作出规定。（见论述）
3.1.1 Discussion—Stainless steels are autopassivating in the n that the protective passive film is formed spontaneously on exposure to air or moisture. The prence of exogenous surface contamination, including dirt, grea, free iron from contact with steel tooling, and so forth, may interfere with the formation of the passive film. The cleaning of the contaminants from the stainless steel surface will facilitate the spontaneous passivation by allowing the oxygen uniform access to the surface. The passive film may be augmented by chemical treatments that provide an oxidizing environment for the stainless steel surface.
3.1.1 论述——在某种意义上说，在暴露到空气和湿气的情况下，保护性的钝化膜自动生成是不锈钢在自动钝化。外生的表面污染，包括：尘土、油脂、来自钢铁加工的游离铁等等，可以影响到钝化膜的生成。通过允许氧气均衡地接触到不锈钢表面，不锈钢表面污染的清洗将会有助于自动钝化。通过为不锈钢表面提供一个氧化环境的化学处理，钝化膜可以得到增强。谨慎英文
3.1.1.1 In this specification, passivation, unless otherwi specified, is defined as the chemical treatment of a stainless steel with a mild oxidant, such as a nitric acid solution, for the purpo of the removal of free iron or other foreign matter, but which is generally not effective in removal of heat tint or oxide scale on stainless steel. In the ca of stainless steels with additions of sulfur for the purpo of improved machinability, passivation may also include the removal of sulfides from the surface of the metal for the purpo of maximizing corrosion resistance.
3.1.1.1 在本技术规范中，除非另有规定，“钝化”被定义为：为了消除游离铁和其它杂质，用温和的氧化剂对不锈钢进行化学处理，例如硝酸溶液，但是“钝化”对于消除不锈钢回火颜色和氧化膜（皮）通常是无效的。为了增强良好的切削加工性的情况下，对于带有硫磺的不锈钢，为了令抗腐性最优化，钝化也可包括金属表面硫化物的去除作业。
