304 Stainless Steel Automotive Spring | Shot Peened, 200,000 Cycle Service Life, Custom Auto Spring Manufacturer

Product Overview

Our automotive spring is precision-manufactured from premium 304 stainless steel, delivering outstanding corrosion resistance, high tensile strength and stable elastic performance for automotive applications.

Each spring undergoes professional shot peening treatment, which compresses the surface stress, eliminates tiny surface defects, greatly improves fatigue resistance and prevents cracking under repeated cyclic loading.

With a tested service life of 200,000 working cycles, this stainless steel spring maintains consistent elasticity even under long-term vibration, temperature fluctuation and harsh working environments in vehicles.

Key Features

✅ Material: 304 Stainless Steel – Excellent rust & corrosion resistance, ideal for automotive exhaust, valve and motor assemblies ✅ Surface Treatment: Shot peening for enhanced fatigue strength ✅ Fatigue Life: Up to 200,000 cycles of repeated operation ✅ Precision wire forming, consistent dimension & stable spring force ✅ Customizable: Wire diameter, shape, force specification available upon request ✅ Wide automotive use: exhaust valve motor, actuator, interior mechanism and other auto components

Applications

Designed for automotive systems, widely used for car exhaust valve motors, actuators, automotive control mechanisms and other auto parts that require repeated elastic movement.
