Ioan,
Here are my answers to your questions below.

1) Can Stainless Steel be blindly considered RoHS compliant? Otherwise said, is there any SS hardware that could have any of the buggers (mainly Cd or Cr6)?
All stainless steels (assuming they are not coated - no reason why they would be, since they are inherently not prone to rust) would pass for Cr(VI) content.
BULK stainless steel does not contain lead and even if it did it could use the 0.3% by weight Pb exemption. However, see what I pulled off of the Health Canada website.

"Health Canada warns Canadians about potential lead exposure from stainless steel rum flasksWarning
2003-18
April 10, 2003

OTTAWA - Health Canada is warning Canadians that use of certain stainless steel liquor flasks may pose a lead exposure risk. The seams and the spout of the flasks in question were fastened together with solder that contains a high proportion of lead. Tests carried out by the Société des alcools du Québec (SAQ) on one brand of flask showed that, within 24 hours, hazardous levels of lead may leach out of the solder into liquid contained in the flasks. Therefore, anyone who drinks liquor or other liquids stored in the flasks for even short periods of time may be at risk of ingesting lead, particularly if the liquid is acidic.

Health Canada has information that gift sets containing these stainless steel flasks which may pose a lead exposure hazard were sold from 1999 to 2003 in provincial or territorial retail liquor outlets across Canada. Flasks sold in the gift sets were approximately 6 oz in size and may be wrapped with leather. Provincial and territorial liquor control boards have issued recalls for two Appleton Estate gift sets, each containing a 375-ml bottle of rum, a Bacardi White Rum gift set, and the Wiser's De Luxe Canadian Whisky gift set. Consumers are advised to contact their local retail liquor outlet for specific product recall, return and reimbursement information.

There is no lead exposure risk associated with drinking the bottled rum, whisky or other liquor included in the gift sets, provided that the liquors were not stored in the accompanying metal flask.

Although no incidents of lead poisoning following use of these flasks have been reported to date, Health Canada is advising Canadians who may have one of these flasks in their possession to stop using it immediately.

Lead is a toxic heavy metal. It can produce harmful effects on human health even at low levels of exposure. If you suspect lead poisoning from use of one of these flasks, contact your family physician who can order a blood test to measure your blood lead level.

Health Canada is investigating the import and sale of this type of liquor flask on the Canadian marketplace and will issue an update to this warning if necessary."



 

2) Also, could some SS fall under the Pb exemption for machining?
See my answer above

 3) And finally, some SS alloys are magnetic, some other aren't. Can SS hardware used in our industry be magnetic?
No clue about this one.

Rudy,

You are close, it's Austenitic and Martensitic. But are they non-conditionally RoHS compliant?

Looks like we have to specify, or check our customers did, 300 series, in order to validate with the magnet... sounds like a plan.

Thanks,

Ioan:

Typically, 300 series steel, which I think is called Austinetic (spelling is probably wrong) is not magnetic, and is much more corrosion resistant.

Type 400 series SS, which I believe is referred to as Martinistic, is a much cheaper grade, and much more prone to corrosion, and is magnetic.

Hi group,

 

A rookie sort of question : can Stainless Steel be blindly considered RoHS compliant? Otherwise said, is there any SS hardware that could have any of the buggers (mainly Cd or Cr6)?

 

Also, could some SS  fall under the Pb exemption for machining?

 

And finally, some SS alloys are magnetic, some other aren't. Can SS hardware used in our industry be magnetic?

 

As you already guessed it, what I am trying to figure out is if I can make an incoming selection based on magnets. If non-magnetic = accept, if magnetic = reject.

 

Thanks,
