Question: If the carbon content is 0.03%, why is it expressed as 022? What does it mean?
Reply #32019-10-03
The carbon content is a range; for example, in Cr17, the chromium content lies between 16.0 and 18.0

Additionally, the old grade 00Cr17Ni14Mo2 is easier to understand. Why did Ni14 in the old grades change to Ni12?

The 022 digital code indicates that the carbon content is less than or equal to 0.03%. Who can explain the details of the drafting code for GBT 20878? Thank you
