Formed springs are engineered elastic components with customized three dimensional geometries manufactured from carbon steel, alloy steel, or stainless steel wire. The wire diameter typically ranges from 0.5 to 12 millimeters with tolerances of ±0.02 to ±0.08 millimeters according to DIN EN 10270. The shear modulus for spring steel is approximately 79 gigapascals, and ultimate tensile strength varies between 1200 and 2200 megapascals. The minimum bending radius is usually defined as 1.5 to 2 times the wire diameter to reduce stress concentration. Stress relief heat treatment is performed at temperatures between 250 and 450 degrees Celsius. Surface coatings include phosphate, galvanized, or epoxy layers with thicknesses from 8 to 20 microns.

The structural design of formed springs is based on bending and torsional stress analysis, with a typical safety factor between 1.5 and 2.5. The post heat treatment hardness for carbon spring steel ranges from 44 to 52 HRC. Load capacity varies depending on geometry and may range from 5 to 5000 newtons. Fatigue life within operational cycles of 10^5 to 10^7 is achieved with a stress concentration factor below 1.8. Quality control includes static load testing, dynamic fatigue testing, and dimensional inspection with 0.01 millimeter accuracy. The permissible angular deviation of spring legs is typically less than ±1 degree.You can order and buy spring from Iran by contacting us through whatsaap and email.
