60Si2Mn Spring Steel Bar

For spring components carrying substantial loads, 60Si2Mn offers a widely used Chinese material option. It is associated with applications such as vehicle and machinery springs where the finished part must withstand repeated deflection without taking a permanent set.

The benefit depends on suitable forming and heat treatment. High strength in the material specification does not guarantee a longer-lasting spring if the surface is damaged or the part is overloaded. The original drawing and service conditions remain important when replacing an existing component.

We can supply 60Si2Mn bar stock with cutting and specified processing. Dimensions and delivery condition should suit the manufacturing route. Any proposed substitute needs review against the required properties and production process rather than a grade-name comparison alone.

More Details

We can quote 60Si2Mn bars and cut blanks to your required sizes. For flat spring parts, we confirm the width, thickness and allowed size variation against your drawing.

Thickness affects how the spring bends under load. If the requested size is unavailable, we will discuss the alternative with you before quoting it as a replacement.

For parts that will be formed, we work from the straight blank dimensions. These may differ from the overall size of the finished spring.

Less Preparation in Your Workshop

We can provide cutting, drilling and other agreed processing before your forming or heat-treatment work.

Send us the drawing with the operations you need completed. We can separate the supplied work from the steps you will handle in your shop.

If later processing includes surface cleanup or grinding, we can account for that in the blank size. This leaves enough material for finishing without adding unnecessary removal work.
