Can sch No without an ‘s’ in HG20553 be used for stainless steel?
Thread Content
Is stainless steel N200 sch20 available? According to HG20553, the Sch No. with a suffix of S is intended only for austenitic stainless steels and cannot be used for carbon steel pipes. So, can the Sch No. without an S be used for stainless steel? Could someone please give me some advice? Thank you!
The suffix plus S is only used for stainless steel that is not austenitic stainless steel; you must have seen it wrong
I really did misread it; thanks for the reminder. However, the suffix with S is only used for stainless steel and cannot be used for carbon steel pipes. So can Sch No without an s be used for stainless steel? I would appreciate some guidance from those who know more, thank you!
Those without S are carbon steel pipes, which are generally not used as substitutes for stainless steel. Sometimes, to save money, corrosion-resistant treatments are applied, such as lining carbon steel with stainless steel, or providing protection against sulfur embrittlement and hydrogen embrittlement
