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.
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.
