Stainless Steel Testing Liquid

A drop of MoCheck 304/316 applied to a horizontal, clean surface dissolves the Molybdenum out of the steel alloy and within a few minutes causes a brown discoloration of the test liquid.
If the Molybdenum concentration is low (below 0,5%) a blank test on a known piece of steel as a standard is advised. In the case of high Mo-concentrations the drop of MoCheck 304/316 will be discolored chocolate brown. If there is no discoloration within the first few minutes, the Mo-content is under 0,15%.
The test should be done at room temperature (15-25°C). Prior to each application the test mixture should be thoroughly shaken. After the test the metal surface has to be thoroughly rinsed with water.
MoCheck 304/316 contains approximately 9% hydrochloric acid. During the application the working instructions have to be followed. MoCheck 304/316 is supplied in two separate components which while separate can be stored for up to two years. To make MoCheck 304/316 ready to use component 2 is filled into the larger bottle and mixed well by shaking with component 1.
In a sealed container the mixture will retain it’s test properties for at least 6 months. Only one drop of the mixed solution is required per test.
The packaging yields about 1.000 drops.
