54A051 - Walter Molybdenum Spot Test Reagent 100ml

Stop Guessing Your Steel Grades

As a welder or fabricator, you know that 304 and 316 stainless steel look exactly the same on the rack. However, they behave very differently in the field, especially when exposed to salt or chlorides. Welding a tank or fitting with 304 when the print calls for 316 can lead to rust, leaks, and expensive rework down the line. The Walter Molybdenum Reagent (54A051) is your pocket-sized insurance policy against these mix-ups. This 100ml bottle contains a chemical solution designed to instantly tell you if that piece of scrap or cut-off is Moly-bearing (316) or standard (304).

Using the reagent is incredibly simple. Just clean a small spot on the metal to ensure it's free of oil and dirt, and apply a drop of the reagent. If the solution changes color, you have confirmed the presence of Molybdenum, which is the secret ingredient in 316 stainless. If it sits there without reacting, you are likely holding 304. This quick check saves you the embarrassment and cost of fabricating an entire assembly out of the wrong material. It is a must-have for any job box, especially for those working in marine, food and beverage, or chemical plant environments where 316 is mandatory.

The 100ml bottle is durable and easy to store in your shop cabinet. It doesn't require batteries, calibration, or special training. It gives you the power to double-check your material before you strike an arc. Whether you are pulling from a remnant pile or verifying a delivery from a new supplier, a quick drop of Walter Molybdenum Reagent gives you the confidence that you are welding the right metal for the job.
