15-5 PH stainless steel is a martensitic precipitation-hardening stainless steel with approximately 15% Chromium and 5% Nickel. It has high strength, high hardness, and excellent corrosion resistance. Strength can be further increased by a single low temperature heat treatment. Compared to 17-4 PH, it offers better transverse toughness and ductility; better mechanical properties in larger cross-sections, and better forgeability. It is readily weldable. It can be machined in any of the several Thermal Conditions available to this grade.

Chemical Composition

Main structural materials: Aluminum alloy (body housing), carbon/alloy steel (internal drive components & magazine), and rubber (grip and protective parts). Typical alloy composition includes Aluminum (85–95%), Silicon (5–12%), Magnesium (<1%), with steel components mainly iron (Fe) with carbon and alloying elements.

Mechanical Properties

Designed for pneumatic operation with high durability. Key characteristics include high impact resistance, wear resistance in the steel driver blade and magazine, and lightweight structural strength from the aluminum housing. Typical operating air pressure range: 70–120 PSI.

Thickness Range

Compatible with 15-gauge angled finish nails, typically ranging from 1-1/4 in to 2-1/2 in (32–64 mm) nail length for trim and finish carpentry applications.

Tolerance

Standard manufacturing tolerance for nail-driving tools and fasteners: ±0.05 – 0.1 mm for nail diameter and mechanical fitting parts, ensuring proper feeding and driving accuracy.

EN10204 3.1

Mill Test Certificate issued by the manufacturer confirming that the material complies with the specified standards, including verified chemical and mechanical test results.

Option for 3.2

Available upon request. Includes the same certification as 3.1 with additional verification by an independent third-party inspector.

Traceability Documentation

Complete traceability provided, including batch or heat numbers, inspection records, and material test reports.

Incoterms

Available under standard international trade terms depending on order agreement.

Delivery Options

Flexible delivery options including direct shipment and consolidated logistics.

Shared Freight (Group Buy Benefit)

Multiple buyers can combine shipments to reduce logistics costs and improve freight efficiency.
