Full title and description

Steel, Corrosion-Resistant, Bars, Wire, Forgings, Extrusions, Mechanical Tubing, Rings, and Stock for Forgings, Extrusions, and Rings — wear and galling resistant alloy (Nitronic 60 / UNS S21800) in solution heat treated condition; issued as SAE AMS5848F (2024 revision F).

Abstract

This aerospace material specification (AMS5848F) defines chemical composition, heat treatment, mechanical property requirements, permitted product forms, and inspection/test criteria for an austenitic, wear- and galling-resistant stainless steel (commonly known as Nitronic 60 / Alloy 60, UNS S21800). It covers bars, wire, forgings, extrusions, mechanical tubing, rings and stock intended for aerospace and related applications where corrosion resistance plus enhanced anti-galling/wear performance are required.

Scope

Specifies requirements for a corrosion- and galling-resistant austenitic stainless steel alloy (Nitronic 60 / UNS S21800) supplied in multiple product forms including bars, wire, forgings, extrusions, mechanical tubing, flash-welded rings and stock for forging/extrusion/ring production. The document sets allowable chemical composition ranges, required solution heat treatment, mechanical property limits, applicable manufacturing and dimensional forms, and inspection/test methods necessary for aerospace use.

Key topics and requirements

• Chemical composition for Nitronic 60 / Alloy 60 (approx. 8.0% Mn, 4.0% Si, 17% Cr, 8.5% Ni, ~0.13% N with balance Fe and controlled C, Mo, etc.).
• Required solution heat treatment and condition designations for supplied material.
• Mechanical property and hardness limits for specified conditions (tensile, yield, elongation, hardness checks and acceptance criteria).
• Permitted product forms: bars, wire, forgings, extrusions, mechanical tubing, rings, and forging/extrusion stock.
• Inspection, testing and certification requirements — chemical analysis, mechanical testing, heat‑treatment verification and typical finishing/quality controls appropriate for aerospace material procurement.
• Intended performance emphasis: elevated corrosion resistance plus improved resistance to galling, fretting and wear for moving or mating components.

Typical use and users

Used by aerospace and defense OEMs, fastener and hardware manufacturers, precision machine shops and component suppliers for parts requiring corrosion resistance combined with anti-galling/wear performance — e.g., valve stems and seats, fasteners, pump components (wear rings, lobes), sliding or mating hardware, pins, bushings, and components exposed to fretting or galling. Procurement/specification groups and quality engineers reference AMS5848F when ordering Nitronic 60 material to ensure conformance.

Related standards

Related material and product standards include other SAE AMS specifications for stainless and corrosion‑resistant steels and UNS cross-reference documents (for example, other AMS specifications covering stainless bar/tube/forgings and UNS S21800 cross-references). AMS5848 is commonly referenced alongside UNS specification listings and supplier technical data sheets for Nitronic 60.
