I started as a R&D engineer in a furniture factory. The factory asked me to find an alternative material to the s-spring and turn it into a project. This material can also be produced and should be cheaper than spring steel. The S-spring is made of 1070 and 1090 spring steels. In order for the material to be used instead of a spring, it must have sufficient strength and sufficient elasticity. The yield strength of 1070 steel is between 400 and 540 Mpa. Its tensile strength is between 620 and 700 Mpa and elongation at break is 10%. If you have alternative material suggestions for this steel, please could you share it?
Kind you regards.
