430 баспайтын болаттан жасалған катушкалар мен парақ

It can rust in harsh conditions such as high humidity or salty air. In less aggressive environments it resists rust and corrosion well, and regular cleaning helps prevent rust.

Yes, with care. 430 is ferritic, with relatively high carbon and no stabilizing elements, so welds are prone to cracking and lose ductility and corrosion resistance. Post-weld annealing restores them, and weld seams need pickling or polishing. For welded parts, stabilized grades such as 439 and 441 weld better and keep their properties without extensive post-weld heat treatment.

410 has more carbon, so it is harder and stronger, especially after heat treatment, with better wear resistance but lower corrosion resistance; it suits cutlery and tools. 430 has less carbon, better corrosion resistance in non-aggressive environments, better formability and a lower cost; it suits kitchen appliances and automotive trim.

Yes. Its 16–18% chromium resists common food acids, and its smooth, non-porous surface is easy to clean. Corrosion resistance is slightly lower than 304, at a lower price, so it suits non-critical kitchenware and utensils.

Yes. It is a ferritic stainless steel and is magnetic.
