Materials ASTM Certified Materials

ASTM Spring Manufacturer

At Stalder Spring, all of the wire springs we fabricate, excluding the stainless steel and low carbon alloys, are ASTM certified steel springs. This certification, created by ASTM International, formerly known as the American Society for Testing and Materials, describes accepted technical standards for a wide range of materials, products, systems, and services.

Oil Tempered Wire
Carbon Steel
Chrome Silicon
Chrome Vanadium
Music Wire

Material Types

At Stalder Spring, our principles are innovation and customer service. We specialize in ASTM spring manufacturing of compression, extension, and torsion springs. At times, this has even resulted in us constructing a new machine for a particularly unusual part.  On top of this, we stock an agreed-upon quantity of client springs to ensure quicker turnaround times for future orders. The materials we offer that are ASTM certified are:

Finishes & Sizing

Stalder Spring also provides a number of finishing services through trusted third party vendors who we have developed relationships with over the years. These services include:

  • Powder Coating
  • Zinc Plating
  • Folsolm Oil 
  • High Corrosion Resistant Coatings
  • Mechanical Zinc Plating 
  • Black Oxide

Spring Design Considerations for ASTM Materials

Material specification is only one component of a successful spring design. Shaping, operating conditions, and manufacturing methods all contribute to the finished spring's performance.

Spring development frequently involves evaluating:

  • Wire diameter
  • Spring rate requirements
  • Deflection range
  • Operating stress levels
  • Environmental conditions
  • Cycle expectations
  • End configuration
  • Assembly constraints

Balancing these variables with material properties helps ensure the spring performs as intended within the final product.

Supporting Prototype and Production Programs

Many projects begin with prototype quantities before advancing into long-term production. Early testing allows engineers to evaluate load characteristics, fit, and performance while verifying that the selected material aligns with the application's requirements.

This development process can help identify opportunities for refinement before production quantities are released, supporting more efficient project execution and improved product consistency.

Frequently Asked Questions

What Does ASTM Mean in Spring Manufacturing?

ASTM refers to material standards developed by ASTM International that define requirements for material composition, testing, and performance characteristics used throughout manufacturing industries.

Why Are ASTM Material Standards Important for Springs?

ASTM standards help establish consistency in material properties, allowing engineers and manufacturers to specify materials with defined performance characteristics.

Do ASTM Material Specifications Determine Spring Performance?

Material specifications influence performance, but spring geometry, design requirements, manufacturing processes, and operating conditions also play significant roles.

How Are ASTM Wire Materials Selected for Different Applications?

Material selection is typically based on factors such as load requirements, fatigue expectations, environmental exposure, operating temperatures, and overall performance objectives.
