Introduction
Stainless Steel 317 Fasteners are widely essential across industrial sectors requiring exceptional resistance to chemical attack, pitting, and crevice corrosion. As a leading Stainless Steel 317 Fasteners Supplier in UAE, SankalPalloys offers a rich selection of premium-grade bolts, nuts, studs, washers, screws, and custom fastener solutions engineered for high-temperature and harsh marine or industrial settings across Dubai, Abu Dhabi, Sharjah, and beyond.
Manufactured using high-grade UNS S31700 austenitic stainless steel, these fasteners feature higher molybdenum contents than standard grades. SankalPalloys ensures every fastener fulfills exact industrial specifications and international quality benchmarks, securing long-term service stability and joint integrity for critical heavy engineering applications.
What are Stainless Steel 317 Fasteners?
Stainless Steel 317 Fasteners are high-strength corrosion-resistant joining elements forged from UNS S31700 chromium-nickel-molybdenum stainless steel. This molybdenum-enhanced alloy delivers significantly superior resistance to chemical environments, organic acids, and chloride pitting compared to standard SS 304 or SS 316 fasteners.
Offered as hex bolts, stud bolts, socket cap screws, plain and lock washers, heavy hex nuts, and threaded rods, SS 317 fasteners perform reliably in applications demanding elevated mechanical stress, high creep strength, and exceptional durability in corrosive media.
Chemical Composition & Mechanical Properties

- Iron (Fe): Balance
- Chromium (Cr): 18.0–20.0%
- Nickel (Ni): 11.0–15.0%
- Molybdenum (Mo): 3.0–4.0%
- Manganese (Mn): 2.00% max
- Silicon (Si): 0.75% max
- Carbon (C): 0.08% max
- Phosphorus (P): 0.045% max
- Sulfur (S): 0.03% max
Mechanical Properties:
- Tensile Strength: 515 MPa min
- Yield Strength (0.2% Offset): 205 MPa min
- Elongation: 35% min
- Superior creep and stress-rupture properties at elevated temperatures
- Exceptional resistance to pitting, crevice corrosion, and chemical degradation
- Robust durability and high load-bearing capacity
Applications of Stainless Steel 317 Fasteners
Chemical & Petrochemical Industry
Stainless Steel 317 Fasteners are critical in securing chemical reactors, storage tanks, scrubbers, acid piping systems, and process equipment handling aggressive acids and solvents.
Oil & Gas Industry
Extensively utilized in offshore platforms, refineries, pipeline flanges, and subsea structures where harsh saline conditions and sour gas environments require robust, failure-proof joining solutions.
Marine & Desalination Plants
Essential for seawater intake systems, pumps, valves, and offshore structures in the UAE, offering outstanding protection against pitting and crevice corrosion from concentrated saltwater.
Pharmaceutical & Food Processing
Ideal for cleanroom equipment, processing units, and sanitary piping systems requiring easy maintenance, high corrosion resistance, and non-contaminating properties.
Power Generation & Heavy Engineering
Widely deployed in boilers, heat exchangers, flue gas scrubbers, and heavy industrial machinery subjected to elevated temperatures and severe mechanical loads.
Why Stainless Steel 317 Fasteners are Preferred
Stainless Steel 317 Fasteners are chosen because they bridge the performance gap between conventional austenitic stainless steels and high-cost nickel alloys. Thanks to their increased molybdenum and chromium ratio, SS 317 fasteners resist severe pitting from sulfur dioxide, chlorides, and organic or inorganic acids.
Additionally, they provide high creep strength, excellent tensile properties at elevated temperatures, and superior durability. Choosing SS 317 fasteners lowers maintenance downtime and prevents joint failures in critical UAE infrastructure and industrial operations.
