Super Duplex UNS S32760 and 316L

[1.8T]

Could someone who understands stainless steel grades tell me whether its ok to use a flange made from Super Duplex UNS S32760 with 316L bends and tube, its for an exhaust downpipe on a turbocharged petrol engine, dont want to buy the flange to find the two shouldnt be used together or something, thanks

Edited to say the S32760 flange would be welded to the 316L, would welding using 316L rod still be ok if the two materials are ok to use together

The short answer is that the duplex flavours of stainless aren't for high temperature applications. More in depth info here... Duplex stainless steels, a simplified guide

Thanks thats that cleared up, does seem a bit strange offering a turbo flange in that grade if its not suitable for high tempatures
