welding stainless steel 4031 to recover depth
(OP)
Dear All,
I have my ferromagnetic type stainless steel 4031 grade machined to the desired shape. since there was a slut with 1600(length)*80(width)*10(depth)mm dimension on the plate wich the machining operator was going to machine it to the mentioned dimensions.
but he has mistaken and machine 2mm extra in depth. and now I have a slut with 1600*80*12.
now I am figuring out to recover the depth of slut using some method like welding or metal spraying and then machine it to the desired depth.
wich welding method and welding rod(electrode) are suitable for the 4031 stainless steel? will it be economical to do so?
since the magnetic properties of the plate is a concern(according to design intent, plate is going to operate in a magnetic solenoid) will welding have an effect on the magnetic properties of the plate?
any comment would really be aprecieted.

the grade is 1.4031/420, as the certificate provided by the seller says.
regarding the heat treat condition, the plate is in as-received condition and we have conducted no heat treatment on the plate, and none of the heat treatment operations are needed for the final fabricated plate.
regards.

You may not want to use this material in the A or N condition. It has poorer toughness and corrosion resistance.
However for welding you really want it annealed, and you want to use a 260C pre-heat for welding.
Then you can re-anneal after welding and Q&T to the final condition.

I am not that many acquaintances with welding terminology. and don't know about N&T or Q&T. if they stand for normalise& temper or Quench and Temper, I am not really sure about this.
and do you know what kind of electrode or wire is needed?
what about the magnetic properties?

The MTR should shoe what the heat treat condition is.
What are the mechanical properties?
There is matching chemistry weld filler available.

the thickness was 20mm in the as-received condition. after machining the slot place we have 8mm thickness at the bottom of the slot.

What is the tensile on your MTR? What is the heat treat condition?

During welding, We got some distortion in the plate!. I have the plate post weld heat treated to compensate distortion. but I am afraid of losing mechanical/physical properties.
I think I am gonna reject this plate completely and try and new plate.

You should be able to repeat any heat treatment, start with normalizing, and then Q&T if needed.
