AWS: SFA 5.9 ER308L

The nominal composition of this wire is 20%Cr &#; 10%Ni. For &#;L&#; grade, the carbon content is <0.03%. The wire is suitable for welding of base metal of similar composition (AISI 301, 302, 304 and equivalent types). Low carbon grade reduces the propensity for carbide precipitation and offers increasing resistance to Intergranular corrosion. The arc & current carrying characteristics assure excellent performance of outstanding bead and surface finish. Autotherme Grade308L can be used in combination with Maxflux SS-4.
Hi JS55,
Thanks for a very quick reply.
I agree ER308L filler wire first freezes as delta ferrite and then gets converted to Austenite leaving slight amount of Delta ferrite in the weld. It is required and essential too to avoid hot cracking of the weld.
I want to increase the delta ferrite content to 14-16% so that its effect on the corrosion property of the material may be tested. Can you help me on this? I am still not sure what should I do. I will definitely try to quench the weld immediately after welding. But I think the transformation of delta ferrite to Austenite is a high temperature phenomenon and by the time my welding is over, it may have already cooled down to a low temperatures and it may not be of any help. It is my pure guess but definitely i will give this a try on coming Monday.
Friends, any other idea to increase the ferrite content on SS304L weld?
Thanks and regards,
Ramakant
