FAQ
Q1: Is X17CrNi16-2 similar to 304 stainless steel?
A: They are different. X17CrNi16-2 has lower Ni content, slightly reduced corrosion resistance, but better machinability and higher hardness potential.
Q2: Can this grade be heat-treated?
A: Yes. It responds to hardening treatments, enabling improved strength depending on the application.
Q3: Is it suitable for seawater?
A: Not recommended for direct seawater due to low Ni. For marine applications, 316/316L or duplex grades are better.
Q4: Do you support small MOQ or mixed-container orders?
A: Yes. For global buyers, we support flexible MOQ and mixed products in one shipment.
Q5: Can it be used for high-temperature components?
A: Suitable for moderate temperature service; for higher temperatures, consider 310/314/253MA.
