Spring Material Selection Guide 

Selecting the right spring material is critical to guarantee service life, elasticity, corrosion resistance and temperature performance of your custom springs. Dowell Spring supplies springs made of various raw materials to meet different industrial working requirements: • Music Wire (SWP-B): High tensile strength, good fatigue performance, widely used for general compression & torsion springs. • 72A /82B Spring Steel: Cost-effective, stable elasticity for conventional spring parts. • Stainless Steel SS201/SS301 / SS304 /: Good rust resistance, suitable for humid and corrosive environments. • 60Si2Mn Silicon Manganese Steel: Excellent for high load and high temperature working scenarios. • 17-7 PH Stainless Steel: High strength, high precision, ideal for aerospace, medical and precision equipment. • Pure Iron / DT4 serial : Soft magnetic material for electromagnetic spring components. Our engineering team will recommend the most suitable material according to your working temperature, load, anti-corrosion requirement and budget.
