ASTM A19311A 在此，奥氏体螺栓材料经过碳化溶液的处理，但是没有经过应变硬化，因此归在的类别或类别。推荐采用相应材料 ASTM A194 的螺母。 Where austenitic bolting materials have been carbide solution treated but not strain hardened, they are designated Class 1 or Class 1A in ASTM A193. ASTM A194 nuts of corresponding material are recommended. ASTM A1932ASTM A194 在此奥氏体螺栓材料经过碳化溶液处理和应力硬化处理，因此归在类别里。推荐采用相应材料的螺母。 3. Where austenitic bolting materials have been carbide solution treated and strain hardened, they are designated Class 2in ASTM A193. ASTM A194 nuts of corresponding material are recommended. ASME B16.345.1.1. 关于应用的范围和强度等级，参阅段 4. For limitations of usage and strength levels, see ASME B16.34 para. 5.1.1. 被钻孔或头部尺寸太小的螺栓不能使用。 5. Bolts with drilled or undersize heads shall not be used. ASTM A19447 对于应用在低温环境的铁素体螺栓材料，推荐采用等级或等级螺母。 6. For ferritic bolting materials intended for service at low temperatures, ASTM A194 Gr. 4or Gr. 7nuts are recommended. ASTM A19422H. 可用于经过淬火和回火的钢螺栓的螺母材料可以是等级和 7. Acceptable nuts for use with these quenched and tampered steel bolts are ASTM A194 Grade 2and 2H. 柱头螺栓的机械性能要求与螺栓相同。 8. Mechanical property requirements for studs shall be the same as those for bolts. 这些是适用于高温应用环境的奥氏体不锈钢阀门的螺栓材料。 9. These are bolting materials suitable for high temperature service with austenitic stainless steel valve materials. 651660 只有等级和材料才能被采用。 10. Only Grades 651 and 660 shall be used.
