Application

Transparent, colourless or yellowish corrosive liquid. A strong oxidizing agent that will attack almost all metals.

Passivation Treatments

• Grades with at least 16% chromium (except free machining grade such as 303):

20-50% nitric acid, at room temperature to 40oC for 30-60 minutes.

• Grades with less than 16% chromium (except free machining grades such as 416):

20-50% nitric acid, at room temperature to 40oC for 60 minutes.

• Free machining grades such as 303, 416 and 430F:

20-50% nitric acid + 2-6% sodium dichromate, at room temperature to 50oC for 25 40 minutes 


Pickling Treatments

• All stainless steels (except free machining grades):

8-11% sulphuric acid, at 65 to 80oC for 5-45 minutes.

• Grades with at least 16% chromium (except free machining grades):

15-25% nitric acid + 1-8% hydrofluoric acid, at 20 to 60oC for 5-30 minutes.

• Free machining grades and grades with less than 16% chromium such as 303, 410 and 416: 10-15% nitric acid + 0.5-1.5% hydrofluoric acid, at 20 to 60oC for 5-30 minutes.

Using Procedure

<div style="text-align: justify;">
High carbon, high chromium martensitic 440C grades which are selected for high hardness and resistance may be exempt from passivation treatments at the discretion of the procuring activity. 
 
PRECAUTION : 
1> Loose iron particles or other foreign particles must be removed or they will appear as rust or stain spots. may become smeared over or imbedded into the surface of corrosion-resistant steel parts. 
2> DO avoid chlorides that, in excess, can cause a harmful flash attack. When possible, use only a good grade of water containing less than about 50 parts per million (ppm) of chlorides. Tap water is usually adequate, and in some cases up In several hundred ppm chlorides can be tolerated. 
 
 
Chlorides: are present in many cleaning agents. This entails risk of pitting corrosion of stainless steel. If a cleaner containing chlorine, chlorides, bleaches orhypochlorites is used it must be afterwards promptly and thoroughly cleaned off.</div>

Note

During processing operations such as forming, machining, tumbling and lapping, iron particles or other foreign particles may become smeared over or imbedded into the surface of corrosion-resistant steel parts. These particles must be removed or they will appear as rust or stain spots.

High carbon, high chromium martensitic 440C grades which are selected for high hardness and resistance may be exempt from passivation treatments at the discretion of the procuring activity.
