Sep 25, 2001 · A collar is similar to a flange except that there are no bolt holes. The collars are connected by "quick release couplings&quot The material specified for the collar is A36.Most of the forging vendors do forging with A105. My question is-which is a superior material for this work A105 or A36.?

Aug 7, 2002 · A105 is a forged carbon steel, it's like C22.8 except some slight difference in chemical composition especially with Carbon. In absence of an european equivalent grade, I assimilite it to C22.8. According to our experience C22.8 can be equivalent to LF2 also (contrary to A105; A105 can work down to -20°F(-29°C) and LF2 to -50°F(-46°C)).

Jul 3, 2015 · A105 & A694 are both forging material. A105 is CS forgings, A694 is carbon and alloy steel forgings. A106 is for seamless CS pipe. Either way, you'll have to check the code to see what is allowed. Is this question just out of curiosity or is there a reason you're trying to replace A694 with A105? "Tell me and I forget. Teach me and I remember.

May 16, 2008 · I'm working on a carbon steel vessel with MDMT of -24degree C, the shell material is ASTM A516 Gr70 and the forgings/flanges are A105. I understand ASME B16.5 flanges are excepted from impact testing up to -29degree C. I've got a heavy neck forging of 152.4mm thk welded into the 35mm thk plate.

Mar 16, 2010 · API RP14E: Para. 4.1 (b) specifies that A105 material should be normalized for service temperatures below 30 F (-1 C). ASTM A105: The ASTM specification itself requires all flanges for service greater than ASME Class 300 be normalized as well as all piping components other than flanges, which are NPS 4 or greater, and intended for service in ...

Oct 11, 2001 · ASTM A105 vs ASME SA105 ? 4. Thread starter Nukie; Start date Nov 17, 2001; Status

Jan 1, 2017 · A181 was replaced with A105 in the ASME Code. Historically, there was a A181-I, A181-II, A105-I and A105-II, with the difference being the tensile strength. Grade I had a minimum tensile of 60 ksi and Grade II had a minimum tensile of 70 ksi for both specifications.

Nov 27, 2001 · ASTM A105 and A216-WCB (or their ASME SA equivalents) are two different product forms. A/SA105 is a forged material specification while A/SA216-WCB is a cast material specification. The chemical composition for each material is essentially the same (low carbon steel) but there may be some very minor differences in exact ranges of minor elements.

Sep 22, 2016 · Hi Guys, I just want to know what is the differences between ASTM A105 and ASTM A234. I have choose ASTM A234 for my utility water line, but supplier supply to me ASTM A105, so is that ok? thank you. Best Regards, Antonio.

Jun 1, 2021 · Nace MR0175 provides exception to use ASTM A105 in place of A105N by para A2.1.3(a) provided hardness doesn’t exceed 187 Brinell Hardness. Check the MTRs to verify this. Next, check the hardness for the weld joint. There are limits set by NACE MR0175. Even though the exception is provided by NACE, many owners still wants A105N.
