C125S 1.1224 Cold Rolled Narrow Spring Steel Strip

 

Grade : C125S Number: 1.1224

Standard:
EN 10132-4: 2000 Cold rolled narrow steel strip for heat treatment. Technical delivery conditions. Spring steels and other applications
 
The steel C125S is used as cold rolled strip for springs and special applications in thicknesses of up to 6 mm and as tempered cold strip in thicknesses from 0.30 to 3.00 mm. The springs made of steel C125S are suitable for highly stressed tension springs, especially in the watch industry, as well as for pen nibs.
 

Dimensions and tolerances
Thickness: 0.1 to 5 mm; Tolerances: +/- 0.008 to 0.11 mm
Width: 10 to 400 mm; Tolerances: +/- 0.15 to 0.60
*accept nonstandard size, please contact with our sales.

 

Our Advantage
1. Precise thickness, uniform hardness. Bright surface, smooth edge.
2. High flatness of board surface, high performance after multiple bending.
3. No cracking after stamping, and the quality is stable. And we provide Self-Inspection Reports and Raw-Material Test Certificates.
4. Professional anti-rust protective packaging. On time delivery, competitive price.
5. Large stock available, no MOQ requirement

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.

 

C125S 1.1224 Cold Rolled Spring Steel Strip Decarburization

For silicon alloyed steels, decarburization shall not exceed 3% of the material thickness per side,for non silicon alloyed steels, decarburization shall not exceed 2% of the material thickness per side when measure data distance of 5mm from the stripe edge
