This Lowing Products 20 pound shot bag contains #304 (food grade) Stainless Steel shot. The shot in this bag is very highly resistant to corrosion. This shot bag is useful when projects involve a more chemically aggressive environment such as salt water. As with all our shot bags, these are built with real Cordura nylon fabric. Cordura has proven to be the most resistant to the everyday abrasion that our shot bags will endure. An occasional rinse with clear tap water is advised to remove dust and grime. If they have been immersed in a corrosive liquid, such as salt water. We advise a complete rinse with soapy water, as in a quarter car wash.

 

These are the BEST ballast bags on the market.

Due to the increasing costs of the "restaurant grade" #304 stainless steel, we have introduced another alloy of stainless steel, #409. The #409 range of stainless contains an alloy of carbon steel and chromium. This is often referred to as "magnetic stainless steel" since it can be picked up with a magnet.

This alloy has saved production costs while still providing a corrosion resistant stainless steel for harsh environments.

For years, Lowing Light & Grip has provided #409 Stainless Steel bags for many underwater applications including divers' training in chlorinated pools, industrial applications in Lake Michigan, as well as ballasts in floods.

We don't recommend the use of #409 stainless steel in applications where prolonged exposure to saltwater (or other corrosive liquids) will be expected.  However, our #304 stainless steel bags can handle more extreme environments, such as these.
