1.4742 material: how can we cast this material?
(OP)
hi. we want to cast 1.4742 steel with a coreless induction furnace. but we have a problem because of this material 1.4742. 1.4742 material has 0,7-1,0 aluminium and 0,12 carbon, 18 chrom. so its difficult that cast this material. we casted but the casting is too bad; it has surface cracks and too many slags on the face. I think its reason Aluminium.( % 1 ) So, what can we do?
- using filter?
- changing gating system?
- using maybe some stabilizator elements for aluminium?
or what? please help me..

I am not aware of any additive to neutralize the effect of aluminium. Vacuum melting and casting this alloy might help.
Learn the rules,so you know how to break them properly.

casting parts have basic shape and it is sand casting. should I use feeder more or less or common?

The cast grades have different chemistry.

2. Liquid Argon dripped very slowly over the top of the melt will create a continuously expanding cloud of inert gas over an air-melt furnace that may be your best option. You don't need a lot, e.g., one cubic inch of pure argon liquid equals approximately 9 cubic yards of pure argon gas! You will need a liquid Dewar and a wand with a porous stone. Call Air Liquide for more details, or check their website.
3. You might also try alloying it up, adding the aluminum under argon just prior to pouring.
Hope that helps.
