FAQ
1. What is X20CrNi30?
X20CrNi30 is a high-nickel austenitic stainless steel with 19–21% Cr and 27–30% Ni, offering excellent corrosion resistance and toughness.
2. Is X20CrNi30 magnetic?
No, it is non-magnetic in the annealed condition.
3. Can it be hardened?
No, strength is obtained through cold working; it cannot be hardened by heat treatment.
4. Recommended applications?
Chemical equipment, shafts, screws, springs, food processing machinery, and marine environments.
5. Can it be welded?
Yes, standard austenitic stainless steel welding techniques apply. Post-weld annealing is recommended for maximum corrosion resistance.
6. Surface finishes and product forms?
Round bar, flat bar, wire, strip; black, polished, peeled, or bright bar finishes are available.
7. Corrosion resistance level?
High; suitable for aggressive environments including chemical and marine conditions.
8. Custom lengths and machining available?
Yes, cut-to-length, precision machining, and tight tolerances are offered.
9. Difference vs X20CrNi17?
X20CrNi30 contains higher Ni content (27–30%) for superior corrosion resistance, while X20CrNi17 is more economical with lower Ni (~6–8%).
