Product Overview
Harris S0FB01 Solar Flux Type B is a fine powder welding flux supplied in a one-pound can for professional welding and fabrication applications. It is designed for use on the back side of suitable weld joints, where it helps create a protective barrier against atmospheric oxygen during the welding cycle. The formulation is intended to help limit oxidation and heat scale, assist with surface cleaning, and support filler-metal flow over compatible base metals.
Type B is intended for stainless steel applications other than grades 309 and 310, as well as precipitation-hardening steels, chrome-moly steels, and other alloy steels with nickel content below 25 percent. Harris specifies an activity range of approximately 2,000°F to 2,900°F (1,093°C to 1,593°C). The product is supplied as dry powder and requires preparation according to the current manufacturer instructions before application. Because the preparation process may involve flammable and toxic solvents, it should be handled only by trained personnel using the current label, Safety Data Sheet, ventilation requirements, personal protective equipment, and workplace procedures. Confirm the base metal, alloy grade, welding process, and application requirements before ordering or using this flux.

FAQ
What does Solar Flux Type B do?
It is formulated to help shield the back of a compatible weld joint from oxygen, reduce oxidation and heat scale, clean the surface, and assist filler-metal flow.
Can it be used on every stainless-steel grade?
No. Harris excludes stainless grades 309 and 310 from the stated Type B applications.
What is the activity range?
Harris specifies approximately 2,000°F to 2,900°F (1,093°C to 1,593°C).
Is the product ready to brush on directly from the can?
No. It is supplied as dry powder and must be prepared according to the current manufacturer instructions and Safety Data Sheet by trained personnel.
Why Buy Harris S0FB01 Solar Flux From Big Frog Supply?
Big Frog Supply identifies the exact Type B part number, one-pound package, confirmed temperature range, and stated material compatibility so welders and purchasing teams can verify the flux against the intended alloy and procedure before ordering.
