Questions regarding the retesting of stainless steel materials

Thread Content

Is it necessary to retest the nitrogen content when rechecking the chemical composition of stainless steel materials?
Reply #22018-05-09
For example, since S30408 specifies a limit for nitrogen content, does that mean retesting is required?
Reply #32018-05-09
Imported materials require retesting of their chemical composition. Recheck all items according to the standards, including nitrogen. For domestically produced Kaiping stainless steel sheets, only mechanical properties need to be retested.
