Standard Specification for Passivation of Stainless Steels Using Electropolishing 使用电抛光钝化不锈钢的标准规范
发布日期: 2018-10-01
1.1 本规范涵盖使用电解抛光程序对200(UNS2xxx)、300(UNS3xxx)和400(UNS4xxx)系列不锈钢合金以及沉淀硬化合金进行钝化。 注1: 在适当的操作条件下,表面钝化与电解抛光同时发生。钝化质量取决于不锈钢的类型、电解抛光溶液的配方和操作条件。不锈钢表面的游离铁被去除,从而提高了耐腐蚀性。通过电解抛光获得的表面平滑也将提高耐腐蚀性。 电解抛光也会去除热色调和氧化皮。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 本规范可能涉及危险材料、操作和设备。本规范无意解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。
1.1 This specification covers the passivation of stainless steel alloys in the 200 (UNS2XXXX), 300 (UNS3XXXX), and 400 (UNS4XXXX) series, and the precipitation-hardened alloys, using electropolishing procedures. Note 1: Surface passivation occurs simultaneously with electropolishing under proper operating conditions. The quality of passivation will depend on the type of stainless steel, the formulation of the electropolishing solution, and the conditions of operation. Free iron on the surface of the stainless steel is removed resulting in improved corrosion resistance. Surface smoothing obtained by electropolishing will also improve corrosion resistance. Electropolishing will also remove heat tint and oxide scale. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This specification may involve hazardous materials, operations, and equipment. This specification does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
