Frequently asked questions

What is duplex S31803?

UNS S31803 is a 22% Cr duplex stainless steel (often A182 F51 as a forging grade) used for flanges in chloride and high-strength service.

S31803 vs S32205?

S32205 (2205) has tightened chemistry versus S31803 and is commonly specified on newer projects. Confirm the exact UNS on the PO.

When to move to super duplex?

Move to S32750 / S32760 when higher PREN and seawater / severe chloride resistance are required.

What belongs on the purchase order?

UNS / A182 class (S31803 or F51), type/facing, size/class, bore/schedule, and MTC / PREN notes if required.

What is this material?

S31803 is a 22% Cr duplex grade with a mixed austenite/ferrite microstructure. It offers higher strength than 316L and improved chloride stress-corrosion resistance. Closely related S32205 (2205) is often preferred on newer projects.

Selection guidance

Confirm S31803 vs S32205 on the datasheet. For higher PREN see S32750 / S32760.

What to put on the PO

Include material grade / ASTM class, flange type and facing, size and pressure class, bore/schedule, quantity, destination, and documentation (EN 10204 3.1 / 3.2, PMI, NACE, TPI). Email sales@savoypipinginc.com.
