ASTM A1082 UNS S32760 Bolt Mechanical Properties & PREN
ASTM A1082 UNS S32760 Bolts Mechanical Properties center on Condition A, the solution-annealed condition. Tensile, elongation and hardness are all fixed by that heat treatment.
Values shown are for the ASTM A1082 Condition A solution-annealed state. Hardness is capped for NACE MR0175/ISO 15156 sour-service compliance - check your mill certificate before design use.

ASTM A1082 UNS S32760 Bolts & Nuts Torque Chart
Bolt torque follows the formula T = K × F × d. F is the target clamp load and K is a friction coefficient set by the lubricant. This holds for super duplex S32760 the same way it does for steel bolting.
Galling Risk
Lower than austenitic stainless, but still lubricate at high preload
Anti-Seize
Use a duplex-rated anti-seize paste on the threads
Xylan 1070 Coating
Dry-film lubricant lowers friction - common on our Malaysia stud bolt orders
Buyer-Specified Torque
We confirm your exact torque target - never a generic figure
Super Duplex S32760 Bolts Thread Pitch Chart & Nut Compatibility
Super Duplex S32760 Bolts thread pitch follows standard ISO metric coarse pitch, UNC/UNF series and DIN 931 for forged hex bolts.
| Nominal Size | M8 | M10 | M12 | M16 | M20 | M24 |
|---|---|---|---|---|---|---|
| ISO Coarse Pitch (mm) | 1.25 | 1.50 | 1.75 | 2.00 | 2.50 | 3.00 |
| Nominal Size | 1/2" | 5/8" | 3/4" | 7/8" | 1" | 1-1/8" |
|---|---|---|---|---|---|---|
| UNC Threads/in | 13 | 11 | 10 | 9 | 8 | 7 |
Nut Compatibility: ASTM A1082 UNS S32760 Bolts pair best with same-alloy S32760 hex, heavy hex or lock nuts to ASTM F468. This gives a like-for-like strength and corrosion match. A lower-alloy stainless nut creates a galvanic mismatch and caps joint strength to the weaker nut. We supplied matching S32760 heavy hex and lock nuts on a Vietnam machine bolt order.
Cryogenic Impact Testing to -101°C & Xylan 1070 Coating
Two options come up often on real S32760 buyer drawings - low-temperature impact testing and a dry-film anti-galling coating. Oshwin arranges both.

Oshwin Overseas Manufacturing Expertise
Oshwin's skilled production line handles material drawing, solution annealing, forging and tapping within our own factory. As an ASTM A1082 UNS S32760 bolts manufacturer, this in-house control helps us hold tight thread tolerance on Condition A stock.
Super Duplex S32760 Bolting Material Combination
Choosing a compatible flange, gasket and nut material for an S32760 bolted joint avoids galvanic corrosion and preload loss.

S32760 Bolts Surface & Coating
Zinc plating and hot-dip galvanizing don't work on super duplex stainless. Those coatings are made for carbon steel, so we don't offer them on S32760 fasteners.

FAQs - ASTM A1082 UNS S32760 Bolts
Condition A is the solution-annealed condition set by ASTM A1082. It's the standard bolting condition most buyers specify. It needs no further heat treatment before use.
UNS S32760 has a PREN of 40 or higher. It resists pitting and crevice corrosion better than standard duplex 2205. This makes it a strong choice for seawater and sour service.
Zeron 100 is the trade name most commonly used for the UNS S32760 super duplex chemistry. ASTM A1082, ASTM A479 and ASTM F468 are the standards buyers reference for bolting, bar and general fasteners in this grade.
Yes. We have supplied Xylan 1070 coated UNS S32760 stud bolts and matching nuts on repeat Malaysia orders. The coating is a dry-film anti-galling lubricant applied after machining.
Super duplex threads gall less than stainless steel. But they still need lubrication at high preload. Use a calibrated wrench with anti-seize, or ask for Xylan 1070 coating. Always confirm your own torque target.
Ex-stock: M8 to M24 metric, 1/2 inch to 1-1/8 inch UNC/UNF. Jack bolts, DIN 931 hex bolts and other non-standard sizes are made to drawing.
Go custom for flange sizes beyond our standard jack bolt range. The same applies for stud bolt lengths past M24. Also choose it when your drawing needs a lock nut, Xylan coating, or cryogenic impact testing to -101°C.
