What soldering flux is recommended for soldering to stainless steel?

Indalloy #2 Flux
To solder directly to stainless steel, Indalloy #2 Flux (activation range 100-371°C) must be used to remove the surface oxides, allowing a clean surface for the solder to wet. This flux is recommended for mechanical assembly joining only.

What type of flux is used for stainless steel?

White flux is useful for brazing copper, brass, steel, stainless steel, and nickel alloys. It has an active temperature range of 1050 -1600°F (565 – 870°C).

Can stainless steel cable be soldered?

Unlike other metals, stainless steel is very difficult to solder. It has a thick oxide layer that prevents melted solder from sticking to its surface.

Does brass stick to stainless steel?

You can even use solder to join copper or brass to stainless steel, you just need the proper flux. The paste flux tends to leave tacky residue that is difficult to clean off. If you must use a paste flux, use it sparingly. Use plumbing (silver) solder only.

How can I join stainless steel without welding?

The technique of brazing is similar to welding, but is less expensive. Also, brazing acts more like an adhesive as it bonds the two metals together with the filler metal….Here is a list of different ways to join metal without welding:

1. Hardware assembly.
2. Spot welding.
3. Riveting.
4. Brazing.
5. Soldering.
6. Glue.

What is the best solder for stainless steel?

tin-silver solders
A range of tin-silver solders is recommended for stainless steels, since they offer greater strength than the tin-lead solders, coupled with high ductility. Their corrosion resistance is also superior.

Is soldering flux the same as brazing flux?

Brazing and soldering use flux as a part of the process. It’s used to clean the metals to be joined, removing any oxidation and preventing any from forming. For instance, flux used in electrical soldering typically contains a rosin core while flux for brazing applications might use borax or other compounds.

What is soldering flux used for?

The main purpose of the flux is to prepare the metal surfaces for soldering by cleaning and removing any oxides and impurities. Oxides are formed when metal is exposed to air and may prevent the formation of good solder joints.

What is acid flux for soldering?

Acid core solder is a highly active inorganic acid type of flux (zinc chloride free) for general purpose soldering applications where a flux cored solder wire is desirable. The work should be allowed to cool undisturbed until the solder solidifies. The flux residue is then removed with a hot water rinse.

Can you weld brass to stainless steel?

Soldering (bold) Soldering and Brazing of stainless steel to itself or to brass or copper works well also. These processes are good alternatives to the welding of stainless steel fittings. They allow the attachment of copper tubing and brass fittings directly onto the stainless steel.

How do you attach brass to steel?

Two answers here:

1. Silver solder will stick to both brass and steel. Clean the two pieces to be joined with sandpaper. Clamp in place. Apply flux.
2. Brazing is stronger and less expensive than silver soldering. As above, but requires an oxy-acetylene torch and apply flux to the brass rod instead of the joint.
