Result440C, with the highest carbon content among the 440 series, has lower weldability. It's more prone to cracking and requires more care when welding, including careful control of the heat input and the use of suitable filler materials. Therefore, while it's possible to weld 440C, it's generally avoided when possible due to these challenges.
