How To Braze Stainless Steel

Brazetyte® fitting part numbers use symbols that identify the size and style of the fitting. Open in a new window.

[US38.97] CM310A 220V 300W 100MM Stainless Steel Solder

You need to find the correct flux and alloy.

How to braze stainless steel. Regardless of the type of work you need done, we guarantee it will be finished by the expected date. There is no need for the protective flux material. Brazetyte® stainless steel tube fittings are designed for use with various sizes of tubing and are intended to be brazed, soldered, or welded directly to the tubing.

It is a maraging stainless steel which, in addition to. Specializing in brazing and annealing for chromium alloys, such as stainless steel, we treat other materials as well, including carbon steel, mild steel, and copper. Braze is used with a flux, which chemically cleans the metal and keeps it clean during the brazing process.

A powder is combined with water to make a paste which is brushed along the joint. Today, our focus is on flux brazing with a torch. So, keep track on these 6 steps and learn how to braze steel:

Step #1 preparation the steel must first be cleaned, so dirt and grease are eliminated. This creates a liquid and gas tight braze between the copper and stainless steel braided hose. We currently use an atmospheric oven to braze brass to stainless steel.

Use 304l, 316l, or 347 stainless steels for your brazing applications rather than 321. Position the metal as desired. We need to apply only the filler material or the braze alloy on the stainless steel parts before heating.

Design brazing welding head, consideration should be given the strength of the joint, assembly method, the position of the solder placed, joint clearance, and many other factors The heating of sst causes chromium oxide to form on the surfaces of stainless components. If needed, use clamps to secure the pieces in position.

You can see a nice collar of silver brazing material on the head of the stainless steel bolt when its done. One thng about stainless is it's trickier to braze because of the oxides which can form. Below is a video demonstrating how to braze copper to stainless steel.

To learn more about our services and. For stainless steel, an acid flux removes oxides from the steel surface and helps the metals stick together. Like silver solder, the braze material bonds with the surface of the metal being joined.

Braze rings are placed at the joint on the copper elbow and flux is applied to the entire surface of the assembly. Brazing/soldering brass to stainless tubing how to braze brass tubing to stainless steel tubing with a high strength silver solder at 1150 degrees, using a propane torch. Emery cloth or wire tool are the most suitable abrasives.

Soldering means low melting temperatures, usually around 400f or less. Stainless steel that is dirty in the factory environment and undergoes brazing services without being cleaned can experience traces of oxidation that tarnish the surface, and lead to corrosion problems down the line. It is important for stainless steel to stay clean in both the factory environment and after it is delivered to the customer.

Brazing being anything higher than 400f, but not high enough to melt the base metals being joined. For example, in the bicycle industry a benchmark tubeset, reynolds 953, is best when brazed rather than welded. For over 40 years, franklin brazing has been a leader in the heat treating industry.

Heat the joint where the two pieces of metal will meet until the joint glows. I’ve broken down the process of brazing copper to stainless steel fittings in a step by step format below. Many grades of stainless steel can be brazed with no problem if the correct alloy rod is used.

We do not employe torch brazing or use brazing. Before you start it’s important for you to understand you can damage the surface of stainless steel by. Apply the brazing rod to the joint while continuing to heat the metal surfaces.

Zinc migrates from the brass to the stainless steel and causes a problem with welding at a. Turns out pre placing filler metal works great because it allows the torch heat to be directed on the areas most needed without prematurely melting the silver braze filler rod. In most cases, an overlapped joint will be stronger and braze together easier than a gapped joint.

Braze on the other hand, does not get drawn into the joint, but is built up on the surface of the metal being joined, so it looks more like a weld. As the braze alloy melts first, it fills the gap between the two portions of the base steel and forms a strong joint. Unlike mild steel, sst is a low vapor pressure material and is frequently used in very high vacuum applications.

As the brazing process occurs in a vacuum, and there is no chance of oxidation. In particular it is advantageous for joining dissimilar materials that cannot be welded together. A discussion started in 2000 but continuing through 2017.
