Stainless Steel vs Alloy Steel Fasteners
While stainless steel offers excellent corrosion resistance, alloy steel provides higher tensile strength for structural applications.
Understanding the application
Stainless grades are often chosen for corrosion requirements, while treated alloy steels can provide high mechanical strength. Their capabilities depend on the exact grade.
Selection & technical considerations
Temperature, chemical exposure and fatigue behavior should be assessed with the joint design. Coated alloy steel and stainless steel are not automatically interchangeable.
Practical checks before use
State grade, property class and treatment requirements. Check compatible nuts, galling controls and the relevant inspection documents.
