YB/T 4700-2018 Iron and steel Determination of the amount of manganese sulfide precipitation phase Electrolytic separation-flame atomic absorption spectrometry

Standard Number: YB/T 4700-2018(YB/T4700-2018)
Chinese:钢铁 硫化锰析出相量的测定 电解分离-火焰原子吸收光谱法
English:Iron and steel Determination of the amount of manganese sulfide precipitation phase Electrolytic separation-flame atomic absorption spectrometry

Effective Date:2019-04-01
Standard Applicability:This standard specifies the method of determining the amount of manganese sulfide precipitation phase by electrolytic separation – flame atomic absorption method. This standard applies to the manganese mass fraction of less than 1.0% and the oxygen mass fraction of less than 0.01% of low alloy steel in the determination of manganese sulfide precipitation phase, the determination of the range (mass fraction): 0.01% ~ 0.20%.
