GENERAL NOTE: Bolting material shall 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 a 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 Classes 150 and 300 joints. See for required gasket practices.

(5) These materials may be used as bolting with comparable nickel and special alloy parts.

(6) This austenitic stainless material has been carbide solution treated but not strain hardened. Use A 194 nuts of corresponding material.

(7) Nuts may be machined from the same material or may be of a compatible grade of ASTM A 194.

(8) Maximum operating temperature is arbitrarily set at 5OO”F, unless material has been annealed, solution annealed or hot finished because hard temper adversely affects design stress in the creep rupture range.

(9) Forging quality not permitted unless the producer last heating or working these parts tests them as required for other permitted conditions in the 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) This ferritic material is intended for low temperature service. Use A 194 Grade 4 or Grade 7 nuts.

(11) This austenitic stainless material has been carbide solution treated and strain hardened. Use A 194 nuts of corresponding material.

(12) This carbon steel fastener shall not be used above 400°F or below -20°F. 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 A 194 Grades 2 and 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.

(15) ASME Boiler and Pressure Vessel Code, Section II materials, which also meet the requirements of the listed ASTM specifications, may also be used.

Grade Identification Marks and Mechanical Properties of Bolts and Screws

Grade Marks and Material Properties for Bolts and Screws. Bolts, screws, and other fasteners are marked on the head with a symbol that identifies the grade of the fastener.

The grade specification establishes the minimum mechanical properties that the fastener must meet. Additionally, industrial fasteners must be stamped with a registered head mark that identifies the manufacturer. The grade identification table identifies the grade markings and gives mechanical properties for some commonly used ASTM and SAE steel fasteners. Metric fasteners are identified by property grade marks, which are specified in ISO and SAE standards. These marks are discussed with metric fasteners.
