Can anyone please tell me what the "X" factor is aand how it is determined in ER80SB2 Weld wire? Please post and/or send to my e-mail address - qc@ejsus.com.
J/X factor requirements, though having been around awhile are beginning to show up more and more in end user specifications, where services in the sensitive temperature range are a concern. Given modern steel making processes few filler metal manufacturers have trouble making the common spec levels, though it is something that often deserves verification. Again, depending upon the service temps and th material involved. It is being used quite commonly for many bainitic and martensitic high temp alloys.
In addition to the previous informative posts, I have had a hard time finding suppliers that will meet X-factor (I have also heard this referred to as "X-Bar" or "X-Bar Factor") in solid wire. For an earlier project with SAW using ER90S-B3, Bohler Thyssen was the only manufacturer I happened to find that would produce it.
Greg, Correct me if I'm wrong (its been awhile), but wouldn't it be the case that it is not so much meeting X/J factor, as it is meeting stringent X/J factor specs(althoug I know there are general recommended ranges). Since the allowable factor would be project or customer specific, and some folks really drive it down. And the fact that some folks just aren't used to declaring X/J factors yet? What factor levels in specs have you been seeing lately?
I guess I should have specified that the X-factor I was trying to get was 15 max. The AWS spec A5.23 addresses the X-factor in its own way by setting P, Sn, Sb, and As limits, but not many people are manufacturing it.
