410UF Stainless Steel
410UF Stainless Steel
(OP)
I require information on composition, mech properties and applications of this grade. Found almost nothing so far on the www.

Without knowing anything else, that's the best I can come up with.

RE: 410UF Stainless Steel
Some heavy googling determined this is a proprietary grade, with a duplex structure. Composition is 11.5Cr-1.4Mn-0.8Ni-0.13Ti-0.1Nb-MCN(350ppm). Also, several complex stipulations about Ti and Nb minima. No idea what MCN means (My brain reached acronym saturation back about 2005.)
In the case of 410UF, UF apparently indicates for 'utility ferritic'. [I hope my quest is not 'ultimately futile'.] It appears to be designed for improved weldability and low temperature toughness.
The goal is to weld this with good low temperature impact properties.
Any suggestions for a filler metal and process? Since it is proprietary we are going from first principles (see composition above). Any experience/advice is welcome; this corner of the stainless universe has avoided me and my career until now.

The current specs call out two different carbon ranges for 410, the lower on is ferritic, the higher martensitic. The low carbon and low N will give good formability.
If this is dual stabilized with Ni added then it is similar to the 439 variants that are used for auto exhaust work.
In light gage this stuff will weld very well. It is commonly welded autogenously. Any filler would need to be matched.

EdStainless, thinks for the info on 439. The application there is different, but there is probably similarity in the fundamental physical metallurgy.
