Stainless Steel SMO 254 Stud Bolts
SMO 254 is a high alloy austenitic stainless steel (UNS S31254) with high chromium, nickel, molybdenum, and nitrogen. It is designed for use in environments where standard grades such as 304 or 316 are quickly corroded. It has excellent resistance to pitting, crevice, and stress corrosion cracking in chloride-containing and marine environments. It is an ideal choice for chemical processing, offshore, and seawater applications. Typical composition is about 19.5–20.5% Cr, 17.5–18.5% Ni, 6.0–6.5% Mo, 0.18–0.22% N, 0.50–1.00% Cu, with low carbon (≤0.020%) and the balance iron, providing high strength, good weldability, and non-magnetic behaviour.
Price of Stainless Steel SMO 254 Stud Bolts
The approximate price of Stainless Steel SMO 254 Stud Bolts per kg/ unit is listed below, along with the factors affecting its final cost.
Approx Price Range
SMO 254 stud bolts are priced higher than standard stainless grades like 304 or 316 due to the higher alloy content. General market pricing tends to fall in the range of ₹160 to ₹500+ per kg, depending on size, thread type, and finish. Bulk orders naturally bring this down.

How to Choose the Right Stainless Steel SMO 254 Stud Bolts Supplier?
To choose the right stainless steel SMO 254 Stud Bolts supplier, follow the steps mentioned below.
Supplier Selection Criteria
Look for suppliers who carry ready stock rather than operating on an indent basis. This matters for urgent replacements and maintenance shutdowns. Check if the supplier is a manufacturer, authorised distributor, or trader, as they all have different lead times and price structures.
Ask about their experience serving your particular industry. A supplier that regularly serves oil and gas customers will be more familiar with what the NACE documentation requirements are than a general fastener distributor.
Technical Considerations
Confirm the supplier can provide material in the exact standard you need, like ASTM A193, DIN, or ISO. Also, check thread form compatibility. Metric and inch threads are not interchangeable. For flange bolting, ask whether they supply matched sets (studs with nuts) or sell them separately.
Quality & Certification Check
Minimum acceptable documentation is an EN 10204 3.1 Mill Test Report (MTR). For critical applications. Ask for EN 10204 3.2, which requires third-party witness inspection.
Other certifications to check:
- NACE MR0175 / ISO 15156 for sour service
- PED certification for EU projects
- Lloyds, DNV, or BV approval for marine/offshore
Do not accept photocopied or undated test reports. Verify heat numbers on the material match those on the MTR.
Procurement Tips for Bulk Orders
- Request a sample or initial test lot from a new supplier before placing large orders
- Clarify packaging; packaging that protects against corrosion is important for items stored outdoors or in humid environments
- Agree on dimensional inspection tolerances and rejection criteria in the purchase order.
- If you have an ongoing requirement, then consider a rate contract to lock in pricing and stock availability
SMO 254 is a high alloy austenitic stainless steel (UNS S31254) with high chromium, nickel, molybdenum, and nitrogen. It is designed for use in environments where standard grades such as 304 or 316 are quickly corroded. It has excellent resistance to pitting, crevice, and stress corrosion cracking in chloride-containing and marine environments. It is an ideal choice for chemical processing, offshore, and seawater applications. Typical composition is about 19.5–20.5% Cr, 17.5–18.5% Ni, 6.0–6.5% Mo, 0.18–0.22% N, 0.50–1.00% Cu, with low carbon (≤0.020%) and the balance iron, providing high strength, good weldability, and non-magnetic behaviour.
Price of Stainless Steel SMO 254 Stud Bolts
The approximate price of Stainless Steel SMO 254 Stud Bolts per kg/ unit is listed below, along with the factors affecting its final cost.
Approx Price Range
SMO 254 stud bolts are priced higher than standard stainless grades like 304 or 316 due to the higher alloy content. General market pricing tends to fall in the range of ₹160 to ₹500+ per kg, depending on size, thread type, and finish. Bulk orders naturally bring this down.

How to Choose the Right Stainless Steel SMO 254 Stud Bolts Supplier?
To choose the right stainless steel SMO 254 Stud Bolts supplier, follow the steps mentioned below.
Supplier Selection Criteria
Look for suppliers who carry ready stock rather than operating on an indent basis. This matters for urgent replacements and maintenance shutdowns. Check if the supplier is a manufacturer, authorised distributor, or trader, as they all have different lead times and price structures.
Ask about their experience serving your particular industry. A supplier that regularly serves oil and gas customers will be more familiar with what the NACE documentation requirements are than a general fastener distributor.
Technical Considerations
Confirm the supplier can provide material in the exact standard you need, like ASTM A193, DIN, or ISO. Also, check thread form compatibility. Metric and inch threads are not interchangeable. For flange bolting, ask whether they supply matched sets (studs with nuts) or sell them separately.
Quality & Certification Check
Minimum acceptable documentation is an EN 10204 3.1 Mill Test Report (MTR). For critical applications. Ask for EN 10204 3.2, which requires third-party witness inspection.
Other certifications to check:
- NACE MR0175 / ISO 15156 for sour service
- PED certification for EU projects
- Lloyds, DNV, or BV approval for marine/offshore
Do not accept photocopied or undated test reports. Verify heat numbers on the material match those on the MTR.
Procurement Tips for Bulk Orders
- Request a sample or initial test lot from a new supplier before placing large orders
- Clarify packaging; packaging that protects against corrosion is important for items stored outdoors or in humid environments
- Agree on dimensional inspection tolerances and rejection criteria in the purchase order.
- If you have an ongoing requirement, then consider a rate contract to lock in pricing and stock availability
