C125S 1.1224 spring steel strip is used to build springs for a great variety of purposes. Below especially the cold rolled (carbon as well as stainless) spring steel strip will be described in detail. The most common production width of spring steel strip is about 300 mm (11.811 inches). As a matter of course spring steel strip can be slit or cut to length (sheets). We supply a very wide range of high carbon and alloys, covering the most stringent industrial requirements. We have also developed a unique know-how in the design of custom solutions for special applications.

Steel C125S, 1.1224 - implementation and specification: C125S, is Non-alloy carbon spring steel is used for leaf springs and springs with small cross-sections. It is characterized by low hardenability and high carbon range in relation to C90S, C75S, C85S, and C67S steel. Designed for spring elements requiring high elasticity and hardness.It does not show corrosion resistance, and during heat treatment it is exposed to decarburization and oxidation, which means that the material should be protected against treatment using a protective atmosphere. Poorly carried out treatment is associated with reduced fatigue strength.Products made of C125S steel and its equivalents are produced in the form of flat semi-finished products - cold rolled strips, small-format thin sheets. Tempering of C125S steel is carried out in oil, and after tempering the product shows the structure of tempered martensite.Products made of C125S steel are characterized by high tensile strength and yield strength. Thermal improvement consists in austenitising the product at a temperature of 780 - 860 and tempering at a temperature of 350 - 500 ℃.

cold-rolled spring steel strips are gaining popularity in various industries. They are increasingly being implemented in engineering projects, through a fairly large number of small component manufacturers, parts and machine components.By making the right choice to buy steel strips, we reduce the amount of waste produced, thereby saving time and space. With a constant focus on the needs and requirements of our customers, we have created a unique offer.

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.
