Which Rivet Materials Benefit More from M42or ASP in the Fastener Industry?

Regarding material construction for processes, specifically rivet punching as it pertains to the fastener industry, M42 is preferred over ASP materials when considering rivet, process difficulty and environment. Here’s a detailed analysis:

When to Use M42:

Because of great heat resistance and good toughness, M42, a high-cobalt high-speed steel, is well suited for rivet punching at medium hardness. Example Use Cases:

Carbon Steel Rivets (Low & Medium Carbon Steel): M42 is the bare minimum to punch these materials now whilst having great wear and heat resistance at a great price.

Stainless Steel Rivets (304/316, etc.) M42 excels for thin or medium size stainless steel rivets with no excessive wear or heat buildup.

Aluminum Alloy Rivets: M42 has high hardness and resists deformation or edge collapse, which is why it is ideal for mid-scale production.

When to Use ASP:

ASP series (ASP23, ASP30, ASP60, etc.) is the powder metallurgy high-speed steels with excellent wearing resistance and longer service life. The materials are perfect for:

High-Strength Stainless Steel Rivets (410, 420, 17-4PH, etc.) — Higher Strength Materials Cause Increased Tool Wear But ASP HSS Endures The Hardshife And Increases Tool Life.

Titanium alloy rivets: Titanium alloy has a high processing temperature. ASP is more appropriate for high-heat energy release and long-duration intensive punching due to its better heat and wear resistance.

Nickel Base Alloy Rivets (inconel, monel) — This high temperature alloy is really tough, and ASP gives more durability than M42, which reduces tool wear and breakage.

High-Precision or Large-Scale Production — If a manufacturing process requires extended tool life or extreme accuracy, ASP’s uniform microstructure helps maintain precision, thus reducing replacement frequency and improving efficiency.

Summary & Recommendations:

High carbon steel, stainless steel, and aluminum alloy rivets are used in applications where cost is a fundamental factor, at which point M42 is a more economically feasible and practical solution.

(410 stainless steel, titanium alloy, nickel-based alloys) ASP has better wear resistance than many of the materials listed above and is applicable for high-strength punching applications when longer tool life is required.

ASP is required for large-scale production, and high-end applications (such as aerospace and precision manufacturing) to improve mold life and punching quality.
