What Is a 17-4 PH Round Bar?
17-4 PH round bar is a cylindrical bar manufactured from 17-4 PH precipitation-hardening stainless steel.
The material is commonly identified by:
- UNS S17400
- Grade 630
- EN 1.4542
17-4 PH is a precipitation-hardening stainless steel that can achieve high strength and hardness through controlled heat treatment.
The British Stainless Steel Association identifies 17-4 PH as X5CrNiCuNb16-4 / 1.4542 / S17400 and notes its combination of good corrosion resistance, high strength and impact toughness. (bssa.org.uk)
Round bar is particularly useful because it can be directly machined into shafts, pins, fasteners, valve components and other cylindrical engineering parts.
Why Use 17-4 PH Round Bars?
The primary reason engineers select 17-4 PH round bars is the combination of mechanical performance and stainless-steel corrosion resistance.
Important characteristics include:
High Strength
17-4 PH can achieve high mechanical strength through precipitation hardening, making it suitable for heavily loaded components.
High Hardness
The material can be age hardened to obtain high hardness levels required for specific engineering applications.
Corrosion Resistance
17-4 PH provides useful corrosion resistance across many industrial environments. The suitability of the material should still be checked against the actual service conditions.
Machinable Product Form
Round bars are convenient for turning, milling, drilling and other machining operations.
Engineering Versatility
17-4 PH round bars can be converted into many different components, making them useful for machinery and equipment manufacturers.

Valve Components
17-4 PH is used in selected valve applications, including valve stems and other components. (bssa.org.uk)
Pump Components
Pump shafts and other cylindrical components may require high strength and corrosion resistance.
Carpenter Technology identifies pumps and impellers among applications for 17-4 material. (carpentertechnology.com)
Fasteners
High-strength stainless steel round bar can be used as feedstock for specialised fasteners and machined fastening components.
Aerospace Components
Selected aerospace components requiring high strength and corrosion resistance can use 17-4 PH material. Carpenter Technology lists aerospace among its application markets. (carpentertechnology.com)
Industrial Machinery
17-4 PH round bars can be machined into gears, shafts, pins, fittings and other engineered machinery components.
17-4 PH Round Bar Specifications
When purchasing 17-4 PH Round Bar Supplier India requirements, the applicable specification should be clearly defined.
Common identification includes:
| Specification / Identification | Reference |
|---|---|
| Material | 17-4 PH |
| UNS | S17400 |
| Common grade | 630 |
| EN designation | 1.4542 |
| ASTM reference | ASTM A564 |
| ASME reference | SA564 |
The exact standard depends on the product form and project requirements.
ASTM International maintains standards covering a wide range of metallic materials and products. (astm.org)
For pressure equipment or other regulated applications, the applicable ASME requirements should be confirmed separately.
17-4 PH Round Bar Dimensions
Industrial round bars are purchased according to the required diameter and length.
A buyer may specify:
- Diameter
- Standard bar length
- Cut length
- Quantity
- Surface condition
- Machining allowance
- Straightness requirement
- Material condition
For example:
Material: 17-4 PH
Diameter: Required diameter
Length: Required length
Quantity: Required quantity
Condition: Required ageing condition
Certificate: Required documentation
Providing these details allows a supplier to determine the appropriate sourcing option.
Heat Treatment and Material Condition
Heat treatment is one of the most important aspects of 17-4 PH.
The material can be solution treated and subsequently aged to develop the required strength and hardness.
Different ageing conditions provide different balances of:
- Strength
- Hardness
- Ductility
- Toughness
The British Stainless Steel Association confirms that different ageing treatments influence the mechanical-property balance of 17-4 PH. (bssa.org.uk)
Therefore, a purchase enquiry should clearly mention the required condition whenever the project specification calls for one.
Machining 17-4 PH Round Bars
17-4 PH round bar is frequently purchased as raw material for machining.
Common machining operations include:
- Turning
- Facing
- Drilling
- Milling
- Threading
- Grinding
- CNC machining
Machining behaviour depends on the supplied material condition.
Manufacturers should therefore establish whether machining will occur before or after final ageing and select tooling and cutting parameters accordingly.
For precision components, dimensional inspection should also be considered after machining and heat treatment.
