Bolting material will not be used beyond temperature limits specified in the governing Code. Notes : 1. Repair welding of bolting material is prohibited 2. These bolting materials may be used with all listed materials and gaskets. 3. These bolting materials may be used with all listed materials and gaskets, provided it has been verified that as Sealed joint can be maintained under rated working pressure and temperature. 4. These bolting materials may be used with all listed materials but are limited to class 150 and class 300 Joints. 5. These materials may be used as bolting with comparable nickel and special alloy parts. 6. This austenitic stainless materials has been carbide solution treated but not strain hardened. Use A194 Nuts of corresponding material. 7. Nut may be machined from the same material or may be of a compatible grade of ASTM a194. 8. Maximum operating temperature is arbitrarily set at 500°F (260°C) because hard temper adversely affects design stress in the creep rupture range. 9. Forging quality not permitted unless the manufacturer tests them as required for other permitted conditions inthe same specification and certifies their final tensile, yield, and elongation properties to equal or exceed the requirements for one of the other permitted conditions. 10. The ferritic material is intended for low temperature service. Use A194 Gr 4 or Gr 7 nuts. 11. This austenitic stainless material has been carbide solution treated and strain hardened. Use A194 nuts of corresponding material. 12. This carbon steel fastener shall not be used above 400°F (200°C). See also note 4. Bolts with drilled or undersized heads shall not be used. 13. Acceptable nuts for use with quenched and tempered Bolts are A194 Gr 2 and Gr 2H. Mechanical property requirements for studs shall be the same as those for bolts. 14. This special alloy is intended for high temperature service with austenitic stainless steel.
