High Carbon Steel Spring Wires
♦ STEEL WIRES ♦
Kromtel carbon steel wires are produced from finest wire rods. These wires are adequate for flattening use and will neither burst nor crack.
Carbon steel wires are mainly used for springs and mattresses, other than those mentioned it is also used for other woven applications; woven cage productions, CO2 welding wires, zig-zag spring wires, music wires and rope wires.
Our products comply with global standards and have quality certificates issued by institutions like ISO and TÜV.
♦ DIN 17223/84 NORM CARBON STEEL SPRING WIRE ♦
(A, B, C, D CLASS GALVANIZED AND PHOSPHATE COATED)
Kromtel’s carbon steel wires comply with the DIN 17223/84 standard and are coated with phosphate and galvanize. They can be acquired as A, B, C and D Class.
