Liquid blackener. (Materials).

* low boiling point

* meets MIL specs

PX-5-L single-component blackening agent for stainless steels -- including martensitic, ferritic, austenitic and Duplex -- also works with cast and malleable irons. This quick-acting blackener is a liquid version of the company's standard compound and has an exceptionally low boiling point of 250[degrees] to 260[degrees]F. The product is typically operated in seven stages: heated alkaline cleaner, cold water rinse, acid activation, cold water rinse, 10-15 minutes of immersion in the blackening bath, cold water rinse and oil. The product meets MIL-DTL-13924D requirements for Class 4 black oxide coatings. Baths use standard mild steel tanks, heat exchangers and fixtures, while dragout is very low. Expert assistance is offered upon request to maximize the customer's stainless steel blackening line.
