Hi experts,
This is related to chemical composition of carbon and low alloy steel per NACE MR0175-2021
Chemical composition for carbon and low alloy steel
Per Clause A.2.1.2 - Carbon & low-alloy steel are acceptable at 22 HRC max. hardness provided they contain less than 1% mass fraction Nickel.
Per Clause 8 - Max. acceptable level for flat-rolled produce is 0.003% mass fraction of sulfur
Max. acceptable level for seamless product is 0.01% mass fraction of sulfur
Conventional forgings with sulfur levels less than 0.025% mass fraction and castings are not considered sensitive to HIC and SOHIC
Is this the only minimum required chemical composition for carbon & low-alloy steel?
Can you please suggest the clause for chemical composition for stainless steels as well?
Regards,
Akash Wagh.
