Stainless Steel 310 Fasteners

Stainless Steel 310 fasteners are made from a high-alloy austenitic stainless steel with high chromium and nickel. They are designed to perform well at high temperatures without losing strength. These fasteners include bolts, nuts, screws, studs, washers, and threaded rods. With about 25% chromium and 20% nickel, SS 310 is more heat-resistant than grades like 304 or 316 and resists oxidation up to 1150°C. It offers moderate corrosion resistance in mildly aggressive environments. It resists oxidation and scaling at elevated temperatures. Commonly used in the petrochemical, heat treatment, power generation, cement, and furnace manufacturing industries.

Stainless Steel 310 Fasteners Price

Approx Price Range

Stainless Steel 310 fasteners typically cost between INR 150 and INR 600 per piece, depending on their type, size, and form. For larger orders, the price may change further based on the required quantity and specific specifications.

Price Per kg

SS 310 fasteners generally range from INR 800 to INR 1,800 per kg in the Indian market. Prices on the higher end usually reflect smaller quantities, special finishes, or certification requirements. Bulk orders tend to bring the per-kg cost down. Prices can also fluctuate based on raw material market rates.

Factors Affecting Price

Raw material cost, fastener type, size, and thread standard all influence the price. Surface finish requirements, order quantity, and certifications like mill test reports or third-party inspection add to it further. If the fasteners are imported, the country of manufacture and applicable duties will affect the final cost as well.

How To Choose The Right Stainless Steel 310 Fasteners Supplier?

Selecting The Right Supplier

Choose a supplier that stocks SS 310 fasteners in the exact sizes and forms you need, ideally in ready stock, since not all carry the full range and lead times vary. A larger inventory of SS 310 bolts, nuts, studs, washers, and other fasteners allows a buyer to choose according to the requirements.

Technical Considerations

The fasteners must meet the applicable standards. ASTM A193 Grade B8T for bolts and ASTM A194 Grade 8T for nuts. Confirm the supplier can provide MTRs, EN 10204 3.1/3.2 certificates and hardness or tensile test data. PED compliance may be required for pressure equipment.

Evaluating Supplier Credibility

Supplier experience in supplying fasteners or piping components. Customer references, export experience, and certifications like ISO 9001 are reasonable indicators. Ask whether they have handled similar industry requirements before, particularly in high-temperature or petrochemical sectors.

Procurement Strategy

For project-based procurement, getting a firm quotation with confirmed delivery timelines is important. Request samples for critical applications before placing a bulk order. Compare pricing across two or three suppliers, but factor in certification costs, packaging, and delivery terms. Cheaper is not always better when documentation requirements are strict.
