Corresponding gauge for your carbon steel wire:
1.40 mm → Falls between SWG 17 (1.422 mm) and SWG 18 (1.219 mm), usually supplied as 17 SWG.
1.45 mm → Very close to SWG 17 (1.422 mm), commonly classified as 17 SWG or supplied as a custom diameter.
Carbon steel wire is widely used in construction, manufacturing, agriculture, handicrafts, wire mesh production, fencing, binding, springs, wire rope and daily civilian fields.
Low-carbon steel wire, being soft and ductile, is ideal for fencing, nails and general binding applications.
Medium-carbon steel wire offers balanced strength and flexibility, making it suitable for springs and wire rope.
High-carbon steel wire provides high tensile strength and excellent wear resistance, and is commonly used for piano wire, cutting tools and prestressing strands.
In the construction industry, high-carbon prestressing steel wire (PC wire) is essential for reinforcing concrete structures, bridges and railway sleepers.
In the automotive and manufacturing sectors, carbon steel wire serves as a key material for seat springs, tire cord, wire rope and various mechanical springs.
It also serves as the base wire for further processing into galvanized wire, PVC coated wire and other coated products.
ROYAL STEEL GROUP carbon steel wire, with the highest quality and strong supply ability, is widely used in steel structure, construction and various industrial wire products.
