The steel has good corrosion resistance in mildly corrosive environments and good resistance to oxidation at elevated temperatures. In the annealed condition the steel is ductile, does not harden excessively during cold work and can be formed using a large variety of roll forming or mild stretch-bending operations, as well as the more common drawing and bending processes. The steel has limited weldability and should not be used in the as welded condition for dynamic or impact loaded structures. Being a ferritic material, 430 is liable to brittle fracture at sub-zero temperatures, and cannot be used in cryogenic applications. As the steel does not contain nickel or molybdenum, it is cheaper than any of the 300 series steels.
430 ay isang mababang-carbon plain kromo ferritic hindi kinakalawang na asero.Bakal ay may mahusay na kaagnasan paglaban sa nang mahinahon kinakaing unti-unti kapaligiran at magandang paglaban sa oksihenasyon sa mataas temperatura.Na in kondisyon bakal ay malagkit, hindi tumigas labis panahon malamig trabaho at maaaring nabuo gamit ang isang malaking iba't-ibang ng roll bumubuo o banayad kahabaan-baluktot na pagpapatakbo, pati na rin ang mas karaniwang mga drawing at baluktot na proseso.Bakal ay may limitadong weldability at ay hindi dapat gamitin sa bilang welded na kondisyon para sa mga dynamic o load ang istraktura ng epekto.Pagiging isang ferritic materyal, 430 ay mananagot sa basagin bali sa sub-zero na temperatura, at hindi maaaring gamitin sa cryogenic application.Tulad ng bakal ay hindi naglalaman ng magtubog sa nikel o molibdenum, ito ay mas mura kaysa sa anumang ng 300 serye steels.
