DIN 17222 C60 1.0601 Cold Rolled Steel Strips for Springs

Cold rolled steel strip for springs is distinguished by high dimensional accuracy and good surface quality and, in the cold rolled + hardened + tempered condition (H + A) offers the possibility of achieving high values of hardness, tensile strength and elastic limit.

C60 1.0601 Introduce

C60 1.0601 steel is an unalloyed medium carbon engineering steel which has 0.57%-0.65% Carbon. It will obtain high hardness and high strength after hardening due to the relatively high carbon content.

C60 1.0601 Dimensions and permissible deviations

Thickness: 0.1 to 4mm; Tolerances: +/- 0.008 to 0.11 mm

Width: 10 to 600mm; Tolerances: +/- 0.15 to 0.60mm

In the production of spring steel wire, a variety of specialized equipment is essential. Shot Peening Machine. Wire Drawing Machine. Phosphating Equipment. Annealing Furnace. Polishing Equipment. Wire Coiling Machine. End Grinding Machine. Tensile and Compression Testing Machine.

Our commitment to excellence and reliability has resulted in long-standing partnerships with some of the biggest names in the industry. Like MW Industries, NHK Spring, Scherdel, Sogefi, Mubea etc. We also have established partnerships with several prominent Chinese steel groups, like Baowusteel, Xinyusteel, Nanjinsteel, Shagang etc.

Our spring steel wire comes in various categories such as music wire, hard drawn wire, oil tempered wire, chrome silicon wire, chrome vanadium wire, stainless steel wire, nickel plated wire, phosphate coated wire, galvanized wire, and copper coated wire.

Spring steel wire is a versatile material that is utilized in the manufacture of a wide array of products. including automotive suspension springs, valve springs, and torsion springs. Beyond springs, paper clips and mattress supports. In addition, spring steel wire is essential in the creation of retaining rings and circlips that are utilized to secure components on shafts or within bores, and in making various types of fasteners. The durability and resilience of spring steel wire also make it a key material in the manufacturing of certain types of cable, fencing, and even some musical instruments, such as piano and guitar strings, where its ability to return to its original shape after deformation is highly valued.
