Hello Sandeep Generally ASS are not stress relieved after welding due to the chances of sensitization i.e carbide precipitation in the temperature ranges of 425 - 900 degrees C. However in certain critical applications for dimensional stability in long service, ASS have to be stress relieved after welding. We have infact successfully carried out SR of ASS (304LN material)at 400 degreesC and 980 degrees C in certain critical jobs as per client requirement. Stress relieving at temperatures below 400°C is an acceptable practice but results in only modest stress relief. Stress relieving at 425 to 925°C significantly reduces residual stresses that otherwise might lead to stress corrosion cracking or dimensional instability in service. One hour at 870°C typically relieves about 85% of the residual stresses. However, stress relieving in this temperature range can also precipitate grain boundary carbides, resulting in sensitisation that severely impairs corrosion resistance in many medi...

http://www.bssa.org.uk/topics.php   all about stainless steel. Effect of austenitic stainless steel composition and heat treatment on cold formability Introduction Alloying elements that help stabilize the austenitic phase reduce the tendency of the austenitic stainless steels to work harden. Nickel additions have been used traditionally to do this, but nitrogen also has a profound affect on stability of the austenite phase. Deep drawing compositions The nickel level was increased in the superseded BS1449 grade 304S16 compared to the 304S15 level (around 8.0%). This enabled the 304S16 grade with around 8.5% nickel to be used for deep drawing applications. Both these grades are covered in BS EN 10088-2 as 1.4301, but the higher nickel variant can be specified as a 'deep drawing' grade. In contrast the higher nickel variants of 316 (1.4435) were developed for improved 'selective' corrosion resistance, originally in pharmaceutical applications, from lower ferrite ...

Austenitic steels are referred as non-heattreable in conventional sense i.e. they can’t be hardened by transformation hardening mechanism (quench & temper) The only suitable method to increase strength/ hardness of austenitic grades is cold working.   In limited uses a surface treatment such as nitriding can also be tried but at the loss of corrosion resistance, however. Following heat treatments apply to Austenitic grades: Solution heat treatment Stress relieving Best Regards, Iqbal  From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of sandy kumar Sent: July 30, 2009 3:49 AM To: materials-welding@googlegroups.com Subject: [MW:2849] effect of heat treatment on Austentic Steel   Can anyone please tell about the effect of effect of heat treatment on Austentic Steel?   Regards Sandeep kumar --~--~---------~--~----~------------~-------~--~----~...
