17-4 PH Round Bar Supplier in India
Looking for a 17-4 PH round bar supplier in India requires more than finding a material name and a price.
For industrial procurement, the supplier needs to understand the required:
- Material designation
- UNS number
- Diameter
- Length
- Quantity
- Heat-treatment condition

- Delivery location
17-4 PH stainless steel round bar is a precipitation-hardening stainless steel commonly identified as UNS S17400 and Type 630.
It is used in engineered components where a combination of mechanical strength and corrosion resistance is required.
Manan Steel & Metals supplies 17-4 PH round bar for industrial procurement requirements from Mumbai, India.
For technical background, see ATI Materials’ 17-4 PH information.
What Is 17-4 PH Round Bar?
17-4 PH is a chromium-nickel precipitation-hardening stainless steel.
The material is capable of developing different mechanical property combinations through controlled heat treatment and aging.
This makes it suitable for components requiring:
- High mechanical strength
- Corrosion resistance
- Controlled hardness
- Heat-treatment capability
- Engineering durability
17-4 PH round bar is commonly machined into shafts, valve components, pump components, fasteners and other industrial parts.
The material is also known as Type 630 stainless steel.
For a detailed technical explanation, see our 17-4 PH stainless steel round bar properties and applications guide.
17-4 PH UNS S17400 and Type 630
When sourcing this material, buyers may encounter multiple identifiers.
| Identification | Details |
|---|---|
| Commercial Name | 17-4 PH |
| UNS | S17400 |
| Stainless Type | Type 630 |
| Material Family | Precipitation-hardening stainless steel |
| Common Product | Round bar |
| Main Characteristic | High strength through precipitation hardening |
Including UNS S17400 in an enquiry can help avoid ambiguity between different stainless steel materials.
However, buyers should also specify the applicable product standard and heat-treatment condition where required.
17-4 PH Round Bar Sizes
The required 17-4 PH round bar size depends on the finished component and machining requirements.
Typical enquiry diameters can include:
- 10 mm
- 15 mm
- 20 mm
- 25 mm
- 30 mm
- 40 mm
- 50 mm
- 60 mm
- 75 mm
- 100 mm
- Larger diameters subject to requirement and availability
These are example enquiry sizes, not a guaranteed stock list.
Availability can vary depending on:
- Diameter
- Length
- Heat-treatment condition
- Specification
- Quantity
- Supply form
Length Options
A buyer may require:
- Standard lengths
- Fixed lengths
- Cut-to-size bars
- Machining allowance
For an accurate quotation, provide the exact required dimensions.
For more detailed information, see our guide to 17-4 PH round bar sizes, ASTM specifications and MTC.
17-4 PH Heat-Treatment Conditions
Heat treatment is an important part of 17-4 PH procurement.
Commonly referenced aging conditions include:
- H900
- H925
- H1025
- H1075
- H1150
These conditions can produce different combinations of:
- Tensile strength
- Yield strength
- Hardness
- Ductility
- Toughness
Therefore, an enquiry for 17-4 PH should not simply state the material name if the engineering requirement specifies a particular condition.
For example:
17-4 PH Round Bar – UNS S17400 – H900
is more precise than:
17-4 PH Round Bar
For technical information about composition and heat treatment, read our 17-4 PH chemical composition and mechanical properties guide.

17-4 PH Round Bar Price Factors
Buyers searching for 17-4 PH round bar price should be aware that there is no single price applicable to every size and specification.
The commercial value can vary according to:
Diameter
Larger diameters can involve different manufacturing and material requirements.
Length
Standard lengths and cut-to-size requirements can affect the quotation.
Quantity
The total quantity and number of pieces can influence commercial terms.
Heat-Treatment Condition
Requirements such as H900 or H1150 may affect processing and certification requirements.
Specification
The required ASTM, AMS or other specification can affect procurement and documentation.
MTC and Inspection

Delivery Location
Freight and logistics depend on the destination and shipment quantity.
Therefore, the best way to request a 17-4 PH round bar price is to provide a complete technical requirement.
17-4 PH MTC and Quality Documentation
For industrial applications, buyers may require a Material Test Certificate (MTC).
Depending on the specification, documentation may include:
- Material designation
- UNS number
- Heat number
- Chemical analysis
- Mechanical test results
- Heat-treatment condition
- Applicable specification
- Product dimensions
- Testing information
When receiving an MTC, the buyer should compare the information with the purchase order.
In particular, verify:
Material → Heat Number → Chemistry → Mechanical Properties → Condition → Specification
This helps ensure that the documentation corresponds to the supplied material.
