Checklist for Spring fracture Steps Recommended to Avoid Spring Fracture All formed/bend Components produced from pre hardened & tempered strips should be stress relieved. All forming & bending should be done in line of grain (length). All edge burrs should be removed or produced in such a way that burrs are minimized. Springs tend to fracture from burrs when stress is applied. Hardening should be carried out in inert atmosphere or in medium of inert gases to avoid surface decarburisations. Process of hydrogen de-embrittlement is a must after electroplating or acid cleaning and should be carried out immediate without any loss of time. Holes, drawing, etc should be done away from edges so as not to make the spring weak.
