ASTM A182 F316 Socket Weld ( SW ) Coupling ASME B16.11 Class 6000

ASTM A182 F316 SW Coupling Fittings are typically used in many industries including food processing, marine, oil & gas,and cooling water systems. Since they are forged into Class 3000 & 6000 high pressure ratings.

Stainless steel pipe fittings are ideal for applications that involve chemicals or liquids that may be corrosive. Along with fighting corrosion, stainless steel pipe fittings will also prevent contamination making it useful to many professionals and those who seek durability and longevity.

ASTM A182 F316 Meaning

ASTM A182 F316 is material grade for forged stainless steel flanges and fittings and supplied in the Solution Annealed condition.

Heat Treatment

The temperature of the forging is not less than the minimum solution temperature 1040℃ and rapidly quenched in 260℃. Heat treatment of forgings may be performed before machining.

Chemical Properties

Mechanical Properties

Corrosion Resistance

ASTM 182 F316 has excellent corrosion resistance when exposed to a range of corrosive environments. However it is not resistant to warm sea water. That can cause pitting and crevice corrosion. It will also suffer from stress corrosion cracking above 60℃.
