Issues regarding the reference to YB/T5092 stainless steel wire grades in NB/T47018.3-2017

2017-08-02View Original

Thread Content

The reference to YB/T5092 in NB/T47018.3-2017 refers to the 2005 version of stainless steel wire grades; however, YB/T5092 has now been updated to the 2016 version, with significant changes in the wire grade specifications. NB/T47018.3 states that for reference documents without a specified date, the latest version applies to this document, and YB/T5092 does not have such a date specified; However, some stainless steel wire grades have changed in these two versions, resulting in a mismatch. How should this be handled when purchasing such wires? ? ? For example: in YB/T5092-2005, there are ER308 (H08Cr21Ni10Si) and ER308H (H06Cr21Ni10); in YB/T5092-2016, there are ER308 (H06Cr21Ni10) and ER308H (H07Cr21Ni10). In NB/T47018.3-2017, there are S308 (H08Cr21Ni10Si) and S308H (H06Cr21Ni10). If all stainless steel welding wires conforming to YB/T5092 standards on the market are produced according to the 2016 version, how can we purchase them based on the YB/T5092-2005 version specified in NB/T47018.3-2017?
