Initially stainless steel is developed for corrosion resistance in sulfuric acid. This feature has been verified that is very successful after many years of practical application.See all results for this questionWhich is the best heat treatment for pipe welding?Induction heating is considered a very safe option for preheat and postweld heat treatment (PWHT) and is commonly used for pipe welding. It also offers benefits for other part geometries, including flat plates for structural steel applications, as well as for shrink-fit applications.See all results for this question
What makes SS 304 L stainless steel so resistant to corrosion?
The austenitic grade stainless steel offers high resistance to corrosion due to the high wt. % chromium and nickel content (1820 and 812, respectively). Due to the low carbon content, the SS 304L is less sensitive to the sensitization problem and offers excellent weldability.See all results for this questionWhat kind of filler do you use to weld 4130 tubing?Some fabricators prefer to use austenitic stainless steel fillers to weld 4130 tubing. This is acceptable provided 310 or 312 stainless steel fillers are used. Other stainless steel fillers can cause cracking. Stainless filler material is typically more expensive.See all results for this questionWelding Square Pipe Roll Forming Machine | Pipe making Square Pipe Roll Forming Machine. LOTOS is professional in manufacturing high-quality steel welding square pipe roll forming machine and welded tube mill machine.

US7399264B2 - High frequency induction welding of ss400 welded pre tubing for greenhouse frame Heat treatment
A process for producing high pressure tubing from austenitic stainless steels. The process entails passing a continuous austenitic stainless steel strip through pre-weld rolls enclosed in a forming housing to produce a continuous tubular shape having opposing edges separated by a longitudinal gap. While the gap is maintained with a seam guide and a liquid-free gas mixture of an inert gas and a ss400 welded pre tubing for greenhouse frame Heat treatmentTIG Welding Chrome-Moly Tubing | Lincoln ElectricA. Thin wall tubing (< 0.120" wall) applications do not typically require the normal 300ºF to 400ºF pre-heat to obtain acceptable results.
