Introduction
Soldering is a process of joining two or more components by forming a bond that is formed by a softening or melting reaction. It typically involves heating a component or material and depending on the application and component, a metallic based alloy for added strength to the joint. As a rule, it is important to use a suitable material for the job as this will affect the resultant bond strength, ease of application and longevity of the joint.
Stainless steel is a popular material to use with soldering, as it is known for its high corrosion resistance, durability and strength. As with any soldering process, it is important to ensure that the correct solder is used depending on the application and component. In this article we will look at the benefits of using steel solder for stainless steel applications.
Benefits of Steel Solder
There are a number of benefits to using steel solder when soldering onto stainless steel components. Firstly, as stainless steel is a durable and corrosion resistant material, using a metallic based alloy is recommended as this will give the joint extra strength. This is especially true when soldering onto components that require a high level of strength and durability.
Another key benefit of using steel solder is the fact that it is able to withstand high temperatures. This is invaluable when soldering onto stainless steel components as higher temperatures are often required when soldering onto this material. Steel solder has a melting point of between 830-950 degrees Celsius, making it ideal for a variety of soldering applications.
Finally, it is important to consider the fact that a steel solder often flows easier than other materials. Because of this, it is easier for the solder to form a strong and effective bond with the stainless steel component. This can be invaluable when working with various stainless steel components, such as joints or valves.
Using Steel Solder for Stainless Steel
When using steel solder for stainless steel, it is important to consider the type of steel being used and the ultimate application. As steel solders are designed to withstand higher temperatures, they may not be suitable for all stainless steel applications. For example, soldering onto thin sheet metal may require a lower melting temperature so as not to cause any damage to the material.
When working with valves or other potential pressure points, it is important to consider the use of a bleed orifice. This orifice can act as an escape route for any melted solder that could accumulate in the joint, potentially causing a blockage.
In terms of the actual soldering process, it is recommended that an oxy-acetylene torch is used with steel solder. This will ensure that the correct amount of heat is produced to effectively form the joint.
Conclusion
In conclusion, steel solder is a great option for use on stainless steel components due to its high strength, durability and the fact that it can withstand high temperatures. However, it is important to ensure that the correct welding process is selected depending on the application, as steel solder may not always be suitable for all applications. When working with steel solder, it is also recommended that an oxy-acetylene torch is used to ensure that the molten solder is applied at the correct temperature.
