1.1 本规范涵盖标称螺纹为0.060至1.500英寸的不锈钢内六角圆柱头螺钉（SHCS）的化学和机械要求。并用于需要一般耐腐蚀性的应用中。 1.2 涵盖了三组不锈钢合金，奥氏体组1和2以及马氏体组5。 1.3 涵盖了四种性能条件:最大85 ksi退火条件（AF）下的奥氏体合金组1和2，最小80 ksi冷加工条件（CW）下的奥氏体合金组1和2，最小102 ksi冷加工条件（CW1），以及最小160 ksi热处理条件（HT）下的马氏体合金组5。 1.4 以英寸-磅为单位的数值应视为标准值。本标准不包括其他计量单位。 1.5 以下预防性警告仅适用于试验方法部分第节 13 ，本规范: 本标准并非旨在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。 1.6 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 chemical and mechanical requirements for stainless steel inch socket head cap screw (SHCS) with nominal thread 0.060 through 1.500 in. and intended for use in applications requiring general corrosion resistance. 1.2 Three groups of stainless steel alloys are covered, austenitic Group 1 and 2 and martensitic Group 5. 1.3 Four property conditions are covered: austenitic Alloy Groups 1 and 2 in an annealed condition (AF) at 85 ksi maximum, in two cold worked conditions (CW) at 80 ksi minimum, (CW1) at 102 ksi minimum, and martensitic Alloy Group 5 in a heat treated condition (HT) at 160 ksi minimum. 1.4 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 The following precautionary caveat pertains only to the test method portion, Section 13 , of this specification: This standard 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. 1.6 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.
