Blueing Salts Temperature at 275-280 degrees
CAS Registry Number sodium hydroxide is 1310-73-2

Sodium hydroxide, solutions is also known as caustic soda, liquid caustic (solutions of 45-75% sodium hydroxide in water), lye, soda lye, sodium hydrate, white caustic, and solution d'hydroxyde de sodium

it's the same lye you can get or order from the truevalue
this is what you get from brownell,s with the low temp stuff
the same CAS Registry Number
 
There is anouther option, though it takes a little time and trouble. Rust blueing. Basicly works like browning the steel, but dip the part in boiling water and turns the brown black as sin. Also very durable and when done rite is stunning.
