What Is 13-8 Mo Round Bar?
13-8 Mo Round Bar is a precipitation-hardening martensitic stainless steel identified by UNS S13800.
The material is designed for applications that require a useful combination of high strength, hardness, fracture toughness and corrosion resistance.
Carpenter Technology identifies 13-8 Mo as UNS S13800 and describes it as a precipitation-hardening martensitic stainless steel with high strength, excellent fracture toughness, useful transverse mechanical properties and resistance to stress-corrosion cracking.
The alloy is particularly relevant when a component needs much higher mechanical strength than conventional stainless steels while still retaining corrosion resistance.
Typical industrial sectors include:
- Aerospace
- Defence
- Energy
- Oil and gas
- High-performance machinery
- Precision engineering
UNS S13800 13-8 Mo Stainless Steel
When purchasing this material, the UNS designation is important.
13-8 Mo: Commercial alloy name
UNS: S13800
Common designation: PH 13-8 Mo
Material type: Martensitic precipitation-hardening stainless steel
Published industry data also associates UNS S13800 with XM-13, ASTM A564 and ASTM A705, while AMS 5629 is an important aerospace material specification for bar and wire.
For a purchase order, a buyer can state:
Material: 13-8 Mo
UNS: S13800
Product: Round Bar
Specification: ASTM A564 / AMS 5629, as applicable
Condition: Solution treated / aged condition as required
Diameter: Required size
Length: Required length
Quantity: Required quantity
Always confirm the exact specification required by the customer’s drawing or project.
For an official industry reference, Carpenter Technology’s 13-8 Mo material information provides the alloy designation, applications and applicable specifications.
13-8 Mo Chemical Composition
13-8 Mo gets its name from its approximate chromium and nickel content, while molybdenum is an important additional alloying element.
A commonly specified chemical composition for UNS S13800 is:
| Element | Typical / Specified Range |
|---|---|
| Carbon (C) | 0.05% max |
| Manganese (Mn) | 0.10% max |
| Silicon (Si) | 0.10% max |
| Phosphorus (P) | 0.010% max |
| Sulphur (S) | 0.008% max |
| Chromium (Cr) | 12.25–13.25% |
| Nickel (Ni) | 7.50–8.50% |
| Molybdenum (Mo) | 2.00–2.50% |
| Aluminium (Al) | 0.90–1.35% |
| Nitrogen (N) | 0.010% max |
| Iron (Fe) | Balance |
These limits are published for UNS S13800 in technical material references.
The actual chemistry of purchased material should always be checked against the applicable specification and Mill Test Certificate (MTC).
13-8 Mo Mechanical Properties
The major attraction of 13-8 Mo is its ability to develop a wide range of mechanical properties through precipitation-hardening treatments.
Carpenter Technology notes that different single-cycle, low-temperature aging treatments can produce a broad range of mechanical properties in 13-8 Mo.
Representative published values demonstrate how strongly the final condition affects performance.
For example, ASM/MatWeb data for H1150 condition lists approximately:
| Property | Representative H1150 Value |
|---|---|
| Tensile Strength | 1000 MPa |
| Yield Strength | 725 MPa |
| Elongation | 20% |
| Density | 7.80 g/cm³ |
These values are representative of a specific condition and should not be applied universally to every 13-8 Mo bar.
Other aging conditions produce considerably higher strengths. For example, published H950 data lists tensile strength around 1550 MPa.
This is why the purchase condition must be clearly defined when ordering 13-8 Mo Round Bar.
Why Engineers Choose 13-8 Mo
Material selection is often about balancing several properties rather than maximizing one property.
13-8 Mo is attractive because it combines:
High strength
Suitable heat treatment can produce very high tensile and yield strength.
Corrosion resistance
The chromium-containing stainless-steel base provides useful corrosion resistance.
Fracture toughness
The alloy is known for strong toughness characteristics, particularly valuable in demanding structural applications.
Stress-corrosion resistance
13-8 Mo is recognized for resistance to stress-corrosion cracking in appropriate environments.
Heat-treatment flexibility
Different aging conditions allow engineers to select a useful balance of strength and toughness.
This combination makes 13-8 Mo different from simply selecting a conventional stainless steel round bar.
13-8 Mo Round Bar Applications
Aerospace Components
13-8 Mo is used in aerospace applications where high strength, toughness and corrosion resistance are required.
Carpenter Technology identifies aerospace and defence among the principal application sectors for 13-8 Mo.
Defence Equipment
High-strength precipitation-hardening stainless steels are relevant to selected defence components that operate under demanding mechanical conditions.
Energy Industry
The material can be considered for selected energy-sector components where strength and corrosion resistance are both important.
High-Strength Shafts and Pins
Round bar is well suited for manufacturing cylindrical components such as shafts, pins, rods and precision-machined parts.
Valve and Mechanical Components
Depending on service conditions, 13-8 Mo can be used for selected high-strength mechanical and fluid-handling components.
Precision Engineering
The combination of strength and corrosion resistance makes it suitable for specialized precision-engineering components.
The final application should always be checked against the material condition, environmental exposure and design requirements.
13-8 Mo Heat Treatment
Heat treatment is a central part of 13-8 Mo material selection.
Unlike ordinary austenitic stainless steel, 13-8 Mo is designed to achieve its required strength through precipitation hardening.
The general process involves:
Solution Treatment
The alloy is solution treated to establish the appropriate metallurgical condition.
Cooling
The material is cooled according to the specified procedure.
Aging
A subsequent aging treatment precipitates strengthening phases and increases the mechanical strength.
The selected aging temperature determines the resulting balance between strength, toughness and ductility.
Published data shows the significant difference between conditions such as H950, H1000, H1100 and H1150.
For this reason, an engineering purchase specification should never simply say “13-8 Mo Round Bar” when a particular mechanical condition is required.
The required aging condition should be clearly identified.
13-8 Mo Machining and Fabrication
13-8 Mo can be machined using conventional metal-cutting operations, but machining practice should take account of the supplied condition.
Typical processes include:
- Turning
- Milling
- Drilling
- Boring
- Threading
- Grinding
Machining performance changes as hardness increases.
A bar in a relatively softer solution-treated condition may be easier to machine than a fully aged high-strength condition.
For precision components, machining allowance, dimensional changes after heat treatment and final grinding should be considered during production planning.
Welding
13-8 Mo can be welded using appropriate procedures, but welding requirements depend on the product condition and service requirements.
For critical aerospace or pressure-related applications, the welding procedure, filler selection and post-weld treatment should be defined according to the applicable engineering specification.

Heat-Treatment Condition
The required aging condition can affect processing, testing and final properties.
Surface Finish
Bright, turned, ground and polished surfaces require different levels of finishing.
Testing
Mechanical testing, hardness testing, ultrasonic testing, PMI and third-party inspection may be required for specific applications.
Quantity
Commercial pricing can vary between small quantities and larger production requirements.
Availability
A particular diameter and aged condition may not always be immediately available, affecting lead time and price.
