Soldering of stainless steel heat exchangers, Shinwa will support the processing.

For brazing stainless steel heat exchangers, which are essential for automobiles and water heaters, please leave it to Shinwa.

In recent years, improving fuel efficiency and reducing exhaust emissions have become important issues for automobiles in addressing global warming and improving air quality. Additionally, household appliances like gas water heaters are designed to use heat efficiently. In such contexts, stainless steel heat exchangers are utilized. Stainless steel has excellent high-temperature corrosion resistance and is widely used in automotive secondary heat exchangers and exhaust heat recovery units for water heaters. Exhaust gases are at high temperatures, reaching 700 to 800 degrees Celsius during full-load operation in vehicles, and gas water heaters generate strongly acidic drain water due to their structure. ◆◆◆ If you are having trouble with brazing, please consult Shinwa! ◆◆◆ The best option for brazing stainless steel heat exchangers is "nickel brazing," which has excellent high-temperature corrosion resistance. Shinwa manufactures nickel brazing paste and sells powders and foil brazing materials. Since we have a vacuum furnace in-house, we can offer "brazing material proposals" and "prototype processing" tailored to our customers' products. We can support those struggling with brazing from prototyping to mass production. Please feel free to contact Shinwa first. *Please download and view our business brochure from the link below.
