UCS (in particular UCS-66) has required impact testing for both my SA 516 and my SA 105 materials. I am now trying to figure out what are acceptable values for the impact .Impact Test – A Charpy V-notch impact test is a dynamic test in which a notched specimen is struck and broken by a single blow in a specially design testing machine. The measured test .Based on industry experience with SA-105 flanges having poor low-temperature toughness properties, the 2019 edition of ASME VIII-1 introduced more stringent requirements for impact . B31.3 and ASME Section VIII indicates SA-105 material (for a flange, in this case) has a MDMT of -20 F. However, B31.3 allows for some materials to be used as low as -155 F .
SA-350: Impact testing is mandatory. SA-105: Impacting test is not mandatory, but if done, minimum design metal temperature (MDMT) could be reduced. 4. Heat Treatment.The SA-105 MDMT curve change is probably the most impactful change to code users in the 2019 coded that will take effect in 2020. It’s a simple issue, but with complex consequences.

A/SA-105 forged flanges supplied in the as-forged condition; . Therefore, if impact testing isn’t a possibility, the manufacturer must use a chemistry that is more restrictive than the chemistry allowed by the control limits listed in individual material ASTM/ASME specifications to prevent brittle fracture and SCC . Minimum Tensile Strength: 70,000 psi (485 MPa) ; Minimum Yield Strength: 36,000 psi (250 MPa) ; Minimum Reduction of area (0.2 % offset method or the 0.5 % extension-under-load method ): 30% ; Maximum Hardness: HBW 197.The usual hardness range for ASTM A105 carbon steel forge material is 137 to 197 HBW.

Further testing has found some of these flanges have extremely low impact test values at -18°C (0°F) and warmer temperatures. However, it has also been reported that testing of some SA-105 flanges resulted in impact testing that was satisfactory well below the -29°C (-20°F) exemption.

Rules for using materials below its MDMT without impact testing. The use of a material at a design minimum temperature colder than −29°C (−20°F) is established by para. 323.2.2 and other impact test requirements. For carbon steels with a letter designation in the Minimum Temperature column, the curve in Figure 323.2.2A of ASME B 31.3 .I often see vessel components such as flanges, nozzle necks and main chambers made from SA-105, SA-53 or SA-106B Pipe. The ASME Code usually exempts these materials from impact testing down to -20F with some exceptions. As summarized in the articles referenced below, brittle fractures have been experienced at temperatures considerably warmer . I couldn't find any statement regarding impact test in Section2 A SA-179 as well as in SA-450 were as in PV elite it shows that it can be used with impact test up to -55°F , I have placed a material requisition requiring impact test report at . zulsaid; If the A 105 will be used at ambient temperature or above, I would not conduct CVN testing, it is really not necessary. IF there is a chance that the service temperature can reach -29 deg C and depending on the application, I would conduct CVN tests if the forging was supplied in an annealed condition.
It is just not safe to use SA 105 in a thick wall ASME VIII-2 vessel at -29 Deg. C ,so why look for impact test exceptions. RE: Self reinforce nozzle (SA105) for -29¦C (-20¦F) . It is possible to order SA 105N with impact test. Also, -29 deg. C is not a very low temperature and my experience says that impact will pass easily. This way, LF2 .•SA-105 fittings and flanges supplied in the as-forged condition are now categorized as ASME impact test exemption Curve A. •ASME B16.5 & ASME B16.47 as-forged flanges are exempt from impact testing if the design temperature is no colder than 0°F. •Fittings and flanges that are normalized after forging are assigned Curve B.

The product to be shipped to the customer has 1" SA-312 316/316L pipe that is to be welded to SA-105 socket weld fittings, designed to ASME B31.3.
(b) When impact testing is necessary, the following toughness values are required. (1) If the specified minimum tensile strength is less than 655 MPa (95 ksi), then the required minimum energy for all specimen sizes shaIl be that shown in Figure 3.3 and Figure 3.4 for vessel parts not subject to postweld heat treat-ment (PWHT) and vessel parts subject to PWHT or nonwelded .1. The document discusses requirements for impact testing of materials according to ASME codes IX and B31.3.
