Carbon Steel CNC Machining Services

Carbon steel relies on carbon content to adjust hardness and tensile strength, featuring low cost, excellent weldability and outstanding mechanical performance after heat treatment. It can achieve adjustable hardness via quenching & tempering to meet heavy load wear-resistant part requirements.

HONGWEN provides custom low/medium/high carbon steel CNC turning, milling and drilling services, with complete heat treatment supporting process (quenching, tempering, carburizing). We serve automotive, mold, machinery, power and construction hardware industries.
