Product Overview

What are SS 410 / 416 Studs?

SS 410 / 416 studs are high-strength, martensitic stainless steel threaded rods or double-ended studs manufactured from ASTM A276/A479 Type 410 or 416 bar stock. These grades are known for their excellent machinability (416) and moderate corrosion resistance (410), combined with high tensile strength after heat treatment. SS 410 offers a good balance of hardness and toughness, while SS 416 is the most machinable stainless steel, making it ideal for precision-threaded fasteners.

SS 410 / 416 studs are widely specified for bolting applications in pumps, valves, turbines, and general engineering where moderate corrosion resistance and high mechanical strength are required. Both grades are magnetic and can be supplied in hardened and tempered or annealed conditions, depending on the application.

Material Chemistry

SS 410 / 416 Chemical Composition

SS 410 / 416 Studs are manufactured from an iron-chromium-nickel alloy with chromium (16–26%), nickel (8–28%), and grade-specific molybdenum additions per ASTM and ASTM A193/A194. Chromium content governs the self-healing passive oxide film; molybdenum (2–6%) enhances chloride pitting resistance; and carbon content determines sensitization risk in welded assemblies.

Why SS 410 / 416 Alloy Composition Matters for Studs

High Chromium Content
The 11.5–14% chromium in SS 410 / 416 provides moderate corrosion resistance, making these studs suitable for mildly corrosive environments and general engineering applications.
Sulfur for Machinability (416)
SS 416 contains elevated sulfur (0.15% min), dramatically improving machinability for precision threads and tight tolerances, ideal for custom stud manufacturing.
Martensitic Structure
Both grades can be hardened by heat treatment, achieving high tensile strength and wear resistance, essential for load-bearing stud applications in pumps, valves, and turbines.
