(OP)
hi all
can anyone let me know what the full chemical and mechanical spec is for 1.4409.
and are there any acceptable tolerances.
we have an issue where the Phosphorus levels are above the permitted allowed of .035
and is there any way of getting that level down in any way

RE: 1.4409
Can't answer about tolerance, but it is not a good idea to have phosphorus above 0.035%, even in a stainless.

the 316 raw plates are melted down and Nickel & Chrome added to spec.
but have no way of bringing the Phosphorus down.
any ideas

You will need to find a better source.

RE: 1.4409
we are now awaiting for a new charge from a new supplier, who has informed us of the P levels are below .3%
RE: 1.4409
Either phosphate surface treatments or fertilizer residues.
In modern commodity Stainless grades it is typical to see 0.030-0.032 values.
In specialty grades we see about 0.020-0.025.
