ёсць 18/10 stainless steel better than 18/8?
Так, 18/10 забяспечвае цудоўную ўстойлівасць да карозіі, better aesthetics, and enhanced durability compared to 18/8. Аднак, 18/8 is more cost‑effective and sufficient for many applications.
The “better” choice depends on the application.
ёсць 18/10 магніт з нержавеючай сталі?
Ніякі. 18/10, быццам 18/8, is austenitic and essentially non‑magnetic in the annealed condition. Cold working can induce weak magnetism.
How can I tell if my cookware is 18/8 або 18/10?
Check the manufacturer’s label, упакоўка, or product description. A magnet test can indicate stainless steel (non‑magnetic) but cannot distinguish between 18/8 і 18/10.
ёсць 18/10 the same as 316 з нержавеючай сталі?
