For combined temperature range of valve body and BOLTING MATERIAL see next NOTES: (a) The user is responsible for assurin g that bolt in g materia l is not used beyond the li mit s specif ie d in the governin g code or regulations. (b) ASME Boil er and Pressure Vessel Code Section II MATERIAL that also meet the requirements of the li sted ASTM specification may also be used. (c) MATERIAL li mitations, restrictions, and special requirements are shown on pressure-temperature tables. (d) Check latest version of ASME as this standard is continuall y updated. Do not use these tables for design or ordering purposes.

2 The above data is extracted from ASME 2009. (e) Note (1) belo w appli es to all grades. NOTES: (1) Repair welding of BOLTING MATERIAL is not permit ted. (2) Where austenitic BOLTING materials have been carbid e solu tio n treated but not s train hardened, they are designated Cla ss 1 or Cla ss 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 materia l are recommended. (4) For li mit atio ns of usage and strength le vels, see ASME para. (5) Bolt s wit h drilled or undersi ze heads shall not be used. (6) For ferritic boltin g materials intended for service at low temperatures, ASTM A194 Gr. 7 nuts are recommended.

3 (7) Acceptable nuts for use wit h 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 servic e wit h austenit ic stain le ss steel valv e materia ls . (10) Nuts may be of the same MATERIAL or may be of c ompatible grade of ASTM A 194. (11) Forgin g quali ty not permit ted unless the producer l ast heating or working these parts tests them as required for other permit ted conditions in the same specification and certifies their final tensil e, y ield, and elongation properti es to equal or exceed the requirements for one of the other permit ted conditions. (12) Maximum operating temperature is arbitraril y set at 260 C (500 F), unless MATERIAL has been annealed solution annealed, or hot f inished, because hard temper adversely affects design stress in the creep-rupture temper r ange.

5 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 s train hardened, they are designated Class 1 or Class 1A. Where austenitic boltin g 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, s train hardened). A193 Gr B7 and Gr L7 are acceptable for NACE (as class II I NACE BOLTING ) service as BOLTING is Non wetted parts , however i f bolts themselves must conform to NACE, t hen B7M, L7M bolts are required. B8M BOLTING being equivalent to 316, automatically conforms to NACE.

6 Temperature range of s tuds 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 .

Go to our website:- We can manufacture exotic grades like Nickel, super duplex F55 and Monel (ASTM A494-M35-1), Cd4M-Cu, Hastelloy C (ASTM A-494 CW12MW) and 317 (C8GM) i n short lead-ti me. www .aus tralianpip eline au*All oy steel BOLTING , A193 Gr B7 bolts and A194 Gr 2H nuts can only be used at moderate temperatures depending on the permissable dif ferential expansion of v alve design which may vary between manufacturers.

7 **ASTM A193 Gr B8/B8M bolt in g can rate from -198 C to 800 C, however many manufacturers of bolt s and/or valves specif y the narrower rating range shown. **For temperatures lo wer t han -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 t han -29 C.
