Thank You Metengr

Thanks for reply and insight. Cheers.

Thank you for the clarification. I agree. By my concern is about the point when you say: "The filler wire(weld) for high strength (ex-75ksi) PQR is too hard (strong) for low strength alloy (ex-55ksi)". Suppose I am creating my own P no Group for similar alloys but not covered by the Code. How...

I am asking whether qualifying a WPS for 75 ksi material will be enough to cover welding a 55 ksi material? Thanks

Thank you for the replies. I think those answers clarify the issue of PWHT. Still I do not understand how to go about materials in the same P no and group combination but with different minimum tensile strength values although the PWHT/(tempering in base metal) are same. I am asking the same...

I have some questions regarding the P No grouping used in ASME B & PV Code (IX). I am going to use specific examples to explain my question. Please note that my questions are not about qualifying welding procedure for certain alloys but I am using them as examples. First a simple hypothetical...

Thanks again. By the way, is there any way to check (right after it has been forged) if the forging has been properly forged before the heat treatment and machining. Sometimes, we find out the grain size is no good after machining and full soltion heat treatment- means all the expense...

Thanks for the reply. I agree that the forging temperature is critical. The reference you have provided recommends a forging temperature of 2150F for large amount of deformation. However, I do not understand how how the temperature will stay lower when it is being deformed heavily. I have...

Thank you for the interest. 1. The Forging company claims that they stay within specified range. I have no way of checking it. 2. The solution treatment temperature is 1800F. The solution times were 3-4 hours. 3.All Forgings are pancake forgings (thickness ranges 4-5 inch). Diameter ranges...

We have been buying A286 forgings for high temperature applications. The stock materials are either ASTM A638 Grade 660 or A891. After forging process, they are being solution treated and double aged. Then the mechanical properties are tested from specimens from the forgings and grian...

Thank you.

Metengr, Thank you for the information.

Unclesyd and Metengr, Thank you for your posts. I have a fundamental background on heat treatment and metallurgy. I was working on different alloys. But my current works requires dealing with HSLA alloys also. That is why I am trying to find a course specifically focuing on HSLA steels instead...

Thank you for all the responses. I have received the following info from steel.org "The Association for Iron and Steel Technology is offering a course June 15-18 re New Developments in High Strength Steels (see attached link) or visit their website, www.aist.org and click the link under...

Unclesyd, I could not find any course listings in their website. I did a search on "course" and results showed information about some courses offered in 2005. I checked their news releases also. There is a members area. Probably, it may contain some details about courses. Anyway, I have...

Thank you Arun and Unclesyd, What I am looking for is separate comprehensive course on HSLA steels, such "stainless steel" offered by ASM and "Superalloys" (www.bwdturbines.com). I could not any course on HSLA steels listed at both ASM and AISI sites. I will contact both ASM and AISI to ask...

Dear Members, I am trying to find a short (upto 5 days) course or seminar on high strength low alloy steels. I am interested in heat treatment, structure and properties. If anyone knows of any course, please let me know. Thank You. mets
