This highly specialized process of advanced engineering produces durable, corrosion-resistant springs for various applications. Beginning with high-quality stainless steel wire or strip, the material is carefully formed, heat-treated, and finished to achieve the required spring properties.

At John Evans’ Sons, we manufacture a comprehensive selection of stainless steel springs that are corrosion-resistant, strong, and low maintenance for medical devices, aerospace, military/defense, and many other applications. Beyond our steel springs, we provide spring assemblies, wire forms, and stampings.

We are dedicated to understanding and exceeding our customers’ expectations through quality, innovation, and excellent customer service. By investing in our facility, machinery, and employees’ education, we continue to uphold our company’s founding values and vision.

Our Stainless Steel Springs

We manufacture several types of in-stock springs as well as customized designs, including:

What Types of Stainless Steel Can Our Customers Choose From?

Selecting the right stainless steel grade for your springs is crucial to ensuring optimal performance, longevity, and resistance to environmental factors. Below are key considerations for different stainless steel types used in spring manufacturing:

1. Grade 301 High-Yield Stainless Steel

Grade 301 high-yield stainless steel has a minimum yield strength of 270,000 psi. This makes it an excellent choice for applications requiring extra-high strength, including:

2. Grade 302 Stainless Steel

A higher nickel content than Grade 301 offers improved corrosion resistance for Grade 302 stainless steel. This steel grade is a reliable option for high-temperature environments with temperatures that reach up to 550°F. Due to these factors, Grade 302 is well-suited for medical applications.

3. Grade 304/304L Stainless Steel

As an industry-standard material for spring manufacturing, Grade 304/304L stainless steel provides a balance of strength, heat resistance, and corrosion resistance. This durable alloy is commonly used in:

  • Automotive Components
  • Chemical Processing Equipment
  • Electronics
  • Food and Beverage Machinery
  • Medical Devices

4. Grade 316/316L Stainless Steel

A favorite for medical and food-grade applications, Grade 316/316L stainless steel is the perfect choice. Grade 316/316L stainless steel is selected for its increased corrosion resistance, particularly in harsher environments exposed to moisture, chemicals, or salt water. Additionally, its low carbon content minimizes carbide precipitation during welding, reducing the risk of intergranular corrosion and ensuring long-term durability.
