We are Riddhi Siddhi Impex, a Mumbai-based Super Duplex Steel S32760 Shims manufacturer and supplier, established in 2002. Our precision lines slit UNS S32760 shim stock to ASTM A240 / ASME SA-240, from 0.03 mm to 5 mm thick at ±0.1 mm width tolerance. As an ISO 9001, 14001, and 45001-certified company, we hold a monthly supply capacity of 400-500 tons and export to more than 60 countries.
Super Duplex Steel S32760 Shims are thin, precision-slit spacers of 25Cr super duplex stainless steel, fitted for levelling, alignment, and gap-setting where chlorides destroy ordinary packing. Copper and tungsten at 0.50 to 1.00% each set the grade apart from its corresponding Alloy S32750, joining chromium and molybdenum in a near 50/50 austenite-ferrite structure. ASTM A240 demands a pitting resistance equivalent (PREN) of at least 40 from every heat, so a clamped shim face holds its set thickness. These shims are used in oil and gas applications and desalination plants.
As one of the Super Duplex UNS S32760 shim suppliers and manufacturers, we slit each shim on our own lines from solution-annealed parent coil sourced from reputed primary mills. Gauges cover 0.03 mm to 5 mm at widths from 3 mm to 2000 mm, with EN 10204 Type 3.1 / 3.2 mill test certificates on request.
We provide ASTM A240 UNS S32760 shims in solution annealed condition, slit in-house to your width, with two surface finishes and four edge profiles as tabulated below.

Tungsten feeds the pitting formula at half the weight of molybdenum, while copper steadies the alloy in reducing acids. ASTM A240 limits follow.
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.030 max |
| Manganese (Mn) | 1.00 max |
| Phosphorus (P) | 0.030 max |
| Sulphur (S) | 0.010 max |
| Silicon (Si) | 1.00 max |
| Chromium (Cr) | 24.0 to 26.0 |
| Nickel (Ni) | 6.0 to 8.0 |
| Molybdenum (Mo) | 3.0 to 4.0 |
| Tungsten (W) | 0.50 to 1.00 |
| Copper (Cu) | 0.50 to 1.00 |
| Nitrogen (N) | 0.20 to 0.30 |
ASTM A240 indicates 750 MPa minimum tensile strength of UNS S32760 shims, with 550 MPa yield and a hardness ceiling of 270 HBW, tighter than the 310 HBW permitted for S32750. Supply is solution annealed only; duplex grades take no cold-worked temper ladder. Minimums stay indicative at foil gauges, and continuous service belongs below roughly 250 °C.

These 5 industries use the Super Duplex Stainless Steel S32760 shims we slit, each clamping precise spacings into service that mixes chlorides, heat, and bolt load.
Riser clamps, wellhead frames, and subsea skids get levelled on S32760 shim packs. Bolted joints in sour seawater are where crevice damage begins, and tungsten widens the margin against it. The 550 MPa yield carries bolt loads without creep.
Acid plants set pump baseplates, reactor flanges, and agitator mounts on Super Duplex SS S32760 shims. Copper earns its place in sulphuric streams that chew through leaner duplex, while hot chloride liquors leave the PREN-above-40 faces intact between turnarounds.
Thermal desalination concentrates hot brine that probes every clamped joint for crevice sites. Contractors pack UNS S32760 shims under pump pedestals, flash chamber internals, and membrane skid rails. Thin gauges follow uneven civil steelwork without cracking through years of evaporator cycles.
Stern gear, thruster mounts, and deck machinery sit on 1.4501 shims in shipyards and ports. Splash-zone duty pairs salt spray with vibration. This grade answers at roughly double austenitic strength, keeping alignment fixed in permanent immersion without coatings.
Bleach plant washers and digesters run hot, acidic, and chloride-heavy together. Maintenance crews fit SDSS S32760 shims under bearing pedestals and drive housings, where compressive strength and corrosion resistance keep clearances stable on continuous lines.
Every consignment of S32760 shim stock leaves our warehouses packed for sea movement worldwide.

Super Duplex Steel S32760 Shims price in India runs around ₹280 to ₹340 per kg. Export orders generally land at $4 to $6 per kg. Tungsten, molybdenum, and nickel surcharges set the base; gauge, width, finish, and quantity move the final figure. Call or WhatsApp us for today's rate.
We manufacture Super Duplex Steel S32760 Shims from 0.03 mm to 5 mm thick, slit to widths between 3 mm and 2000 mm at ±0.1 mm tolerance.
S32760 shims differ from S32750 shims through 0.50 to 1.00% each of tungsten and copper, which S32750 leaves out. Both fall under ASTM A240 with PREN above 40; the additions buy extra crevice corrosion margin in hot chlorides.
Yes, Super Duplex S32760 shims can be slit on our in-house lines to any width from 3 mm to 2000 mm, held to ±0.1 mm.
The price of Super Duplex S32760 shims is around ₹280 to ₹340 per kg in India and $4 to $6 per kg for export, moving with alloy surcharges, gauge, and quantity.
