What Is 17-4 PH Round Bar?
17-4 PH Round Bar is a precipitation-hardening stainless steel used where a combination of strength, hardness and corrosion resistance is required.
The material is internationally identified under several designation systems. Buyers may know it as 17-4 PH, Type 630, UNS S17400, EN 1.4542 or SUS 630, depending on their country, engineering standard or procurement specification.
Outokumpu identifies its 17-4PH material as EN 1.4542, ASTM Type 630 and UNS S17400, with a precipitation-hardening microstructure.
This makes understanding the different names important when sourcing material for international projects.
For buyers searching for a 17-4 PH Round Bar Supplier India, matching the requested designation, dimensions, condition and applicable standard is an important part of procurement.
17-4 PH International Designations
One reason buyers may have difficulty finding the correct material online is that the same alloy is searched under different designation systems.
| Designation System | Common Designation |
|---|---|
| Commercial name | 17-4 PH |
| ASTM Type | Type 630 |
| UNS | S17400 |
| EN | 1.4542 |
| JIS | SUS 630 |
| Material family | Precipitation-hardening stainless steel |
Outokumpu lists 17-4PH as 1.4542 / Type 630 / S17400 / SUS 630 in its material designation information.
Therefore, an enquiry written as UNS S17400 Round Bar, Type 630 Round Bar, 1.4542 Round Bar or SUS 630 Round Bar may refer to the same general 17-4 PH material family.
Key Properties of 17-4 PH
17-4 PH is designed for applications where ordinary material strength is not sufficient and corrosion resistance is still important.
Important characteristics include:
- High strength after suitable heat treatment
- Good hardness potential
- Good corrosion resistance
- Precipitation-hardening capability
- Useful machinability in suitable conditions
- Good dimensional stability during appropriate age-hardening processes
- Suitable for demanding industrial components
ASTM A564/A564M covers hot-rolled and cold-finished age-hardening stainless-steel bars and shapes, including Type 630. The standard covers rounds, squares, hexagons and other bar shapes.
The final mechanical properties depend strongly on the specified material condition and heat-treatment route, so buyers should identify the required condition when requesting a quotation.
17-4 PH Round Bar Specifications
When purchasing 17-4 PH Round Bar, the specification should be defined according to the actual application.
| Parameter | Typical Requirement |
|---|---|
| Material | 17-4 PH |
| ASTM Type | 630 |
| UNS | S17400 |
| EN | 1.4542 |
| JIS | SUS 630 |
| Product Form | Round Bar |
| Manufacturing Route | Hot Rolled / Cold Finished / As specified |
| Condition | Solution Treated / Age Hardened as required |
| Diameter | As per enquiry |
| Length | As per enquiry |
| Inspection | As specified by purchaser |
| Test Certificate | Available as required |
ASTM A564/A564M specifically covers hot-finished and cold-finished rounds and other shapes in age-hardening stainless steels.
Chemical Composition of 17-4 PH
17-4 PH contains chromium and nickel along with copper and niobium additions that support its precipitation-hardening characteristics.
A typical composition reported by Outokumpu for 17-4PH includes approximately 15.5% chromium and 4.8% nickel, with copper and niobium among the other alloying additions. Actual composition depends on the applicable standard and product specification.
| Element | Typical Role |
|---|---|
| Chromium | Supports corrosion resistance |
| Nickel | Contributes to alloy structure and toughness |
| Copper | Supports precipitation hardening |
| Niobium | Supports precipitation-hardening behavior |
| Carbon | Controlled at a relatively low level |
For production or critical engineering applications, the purchase specification and material test certificate should be checked rather than relying only on typical composition values.
Applications of 17-4 PH Round Bar
The combination of strength and corrosion resistance makes 17-4 PH useful across several industrial sectors.
Common applications include:
Oil & Gas Equipment
Used for components requiring strength and corrosion resistance in demanding environments.
Chemical Process Equipment
Suitable for selected components where mechanical strength and corrosion resistance are required.
Pump Shafts
17-4 PH is used for pump-related components where strength and dimensional reliability are important.
Valves and Flanges
The material can be specified for industrial valve and flange components.
Gears and Mechanical Components
Its precipitation-hardening capability makes it suitable for selected high-strength mechanical parts.
Aircraft Components
17-4 PH is used in certain aerospace components where its strength-to-corrosion-resistance combination is useful.
Industrial Fittings
The material is also used for fittings and other engineered components.
Outokumpu lists applications including oil-field equipment, chemical process equipment, fittings, pump shafts, gears, paper-mill equipment, aircraft parts, flanges and valves.
Why Choose 17-4 PH for Industrial Components?
The main attraction of 17-4 PH is the ability to obtain a useful combination of mechanical strength and corrosion resistance from a precipitation-hardening stainless steel.
For industrial buyers, this can make the material relevant when a component needs more strength than a conventional corrosion-resistant material can provide while still requiring stainless-steel corrosion performance.
The material is particularly interesting for:
- Precision mechanical components
- High-strength shafts
- Industrial fittings
- Valves
- Pump components
- Gears
- Aerospace-related components
- Oil and gas equipment
The appropriate heat-treatment condition should always be selected according to the component’s required mechanical properties and operating environment.
