H0Cr20Ni10Ti H08Cr19Ni10Ti (ER321) to replace the standard YB/T5092-2005? Only H08Cr19Ni10Ti (ER321), it is not written to replace the one ah, whether there is a substitute for national notice? For the pressure vessel, to use H0Cr20Ni10Ti but the seller said this is a veteran, H08Cr19Ni10Ti (ER321) is a new grade, but can not find alternative basis?
If not there will be accountability and a standard version of the standard difference, look for the advice on the Standard Version, usually the new standard will be stated in the preface and a version of the difference and reason for replacement, if not to look at the last version.
The term "H0Cr20Ni10Ti" does not exist in standard books. It is only a term used by some manufacturers. The term "ER321" is used only in the American Standard for welding materials. There are two standards for stainless steel solid wire in our country now. One is the standard GB/T17854-1999 for submerged arc welding wire, and the other is the newly updated standard of Metallurgical Department of YB/T5092-2005. Another precursor to this standard was YB/T5092-1996. The standard for metallurgy is now in general use, so H08Cr19Ni10Ti is the most standard name. I estimate that your drawings are required to use H0Cr20Ni10Ti, but the supplier cannot provide the same material certificate. These two kinds of welding wire are in fact of the same material, no difference. If you want to meet the requirements of Party A, you must communicate with the manufacturer. There is no other way!
