Product Code:SAE AMS5513
Title:Steel, Corrosion-Resistant, Sheet, Strip, and Plate, 19Cr - 9.2Ni (SAE 30304), Solution Heat Treated
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers a corrosion-resistant steel in the form of sheet, strip, and plate.These products have been used typically for formed and drawn parts requiring corrosion resistance up to 800 掳F (427 掳C), but usage is not limited to such applications. Welding, brazing, or other exposure to temperatures over 800 掳F (427 掳C) during fabrication may impair corrosion resistance.

适用范围
JB/T 8559-1997 本标准采用了API 601-1985《用于突面管法兰与法兰连接的金属垫片》中对垫片尺寸公差要求，规定了表征垫片密封性能的三项性能指标：压缩率、回弹率和气体泄漏率。 本标准与JB/T 6369-92《柔性石墨金属缠绕垫片 技术条件》、JB/T 6628-93《柔性石墨复合增强（板）垫》等标准共同构成了密封用垫片产品的系列标准。 本标准规定了金属包垫片的代号及标记、技术要求、试验方法和检验规则等内容。 本标准适用于管法兰用金属包非金属填充材类的金属包垫片。
