GENERAL NOTES: (a) The user is responsible for assuring that BOLTING MATERIAL is not used beyond the limits specified in the governing code or regulations. (b) ASME Boiler and Pressure Vessel Code Section II MATERIAL that also meet the requirements of the listed astm specification may also be used. (c) MATERIAL limitations, restrictions, and special requirements are shown on pressure-temperature tables. (d) Check latest version of ASME as this standard is continually updated. Do not use these tables for design or ordering purposes. The above data is extracted from ASME 2009.
3 (e) Note (1) below applies to all grades. NOTES: (1) Repair welding of BOLTING MATERIAL is not permitted. (2) 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. (3) Where austenitic BOLTING materials have been carbide solution treated and strain hardened, they are designated Class 2 in astm A193. astm A194 nuts of corresponding MATERIAL are recommended. (4) For limitations of usage and strength levels, see ASME para. (5) Bolts with drilled or undersize heads shall not be used. (6) For ferritic BOLTING materials intended for service at low temperatures, astm A194 Gr.
4 7 nuts are recommended. (7) Acceptable nuts for use with quenched and tempered steel bolts are astm A 194 Grade 2 and 2H. (8) Mechanical property requirements for studs shall be the same as for bolts. (9) BOLTING materials suitable for high-temperature service with austenitic stainless steel valve materials. (10) Nuts may be of the same MATERIAL or may be of compatible grade of astm A 194. (11) 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.
5 (12) Maximum operating temperature is arbitrarily set at 260 C (500 F), unless MATERIAL has been annealed solution annealed, or hot finished, because hard temper adversely affects design stress in the creep-rupture temper range.

8 *Alloy steel BOLTING , A193 Gr B7 bolts and A194 Gr 2H nuts can only be used at moderate temperatures depending on the permissable differential expansion of valve design which may vary between manufacturers. ** astm A193 Gr B8/B8M BOLTING can rate from -198 C to 800 C, however many manufacturers of bolts and/or valves specify the narrower rating range shown. **For temperatures lower than -200 C (-325 F) astm A320 Gr B8/B8M BOLTING must be impact tested. All L7 bolts and Grade 4 nuts must be charpies impact tested for service temperature lower than -29 C. The above chart shows the combined temperature range, taking into account the valve and BOLTING MATERIAL ratings.
9 Refer to astm pressure/temperature charts. For limitations of usage and strength levels refer ANSI. Where austenitic BOLTING materials have be carbide solution treated but not strain hardened, they are designated Class 1 or Class 1A. Where austenitic BOLTING materials have been carbide solution treated and strain hardened, they are designated Class 2. In B8 and B8M, Class 2' is recommended for higher classes 900lb and above in larger sizes depending on temperature due to it's higher tensile strength (carbide solution treated, strain hardened). A193 Gr B7 and Gr L7 are acceptable for NACE (as class III NACE BOLTING ) service as BOLTING is Non wetted parts , however if bolts themselves must conform to NACE, then B7M, L7M bolts are required.
10 B8M BOLTING being equivalent to 316, automatically conforms to NACE. Temperature range of studs can vary widely depending on size, stud, manufacturer, bonnet enclosure and valve manufacturers calculation. Also refer to astm standard for design temperature rating' of BOLTING .
