Chanchai Stainless pushes out these pipes in Bangkok, and honestly, they’re everywhere for a reason. 304L is basically the cooler, more chill cousin of regular 304—less carbon, which means it won’t freak out and rust when you weld it. It’s a big deal for anything that needs to stay squeaky clean and last forever: food factories, pharma, chemical plants, the works. These pipes take a beating, handle heat swings, and just keep going. Plus, Chanchai doesn’t skimp on quality, so you know you’re not getting junk.
304L pipes are loaded with 18–20% chromium, 8–12% nickel, and super-low carbon (under 0.03%). That low carbon is what keeps it from going all weird and grainy after welding, so it stays strong and doesn’t start falling apart at the seams. You get a tensile strength around 485 MPa, yield strength in the 170–200 MPa zone, and it’s nice and stretchy—40% elongation or more. The austenitic structure? Fancy word for “it doesn’t rust easily and can take the heat up to 870°C.” Plus, you can weld and shape it all day long without drama.

We ensures the highest quality for Stainless Steel 304L Pipes through rigorous testing, including chemical analysis, mechanical testing, and dimensional verification. We provide comprehensive certificates, including material test certificates (MTC) and compliance reports, guaranteeing the pipes meet international standards for performance, durability, and reliability in every application.
Stainless Steel 304L ERW (Electric Resistance Welded) pipes are produced by welding stainless steel strips, offering low-carbon content for excellent weldability and corrosion resistance in various applications.
Stainless Steel 304L EFW (Electric Fusion Welded) pipes are made by fusing stainless steel plates, providing strong, durable pipes with low carbon content, ideal for chemical and food processing industries.
Stainless Steel 304L LSAW (Longitudinally Submerged Arc Welded) pipes are created using a submerged arc welding process, offering high strength and corrosion resistance, suitable for large-diameter applications.
Stainless Steel 304L Seamless pipes are manufactured without welding, providing uniform strength and resistance to corrosion and high temperatures, ideal for critical applications in chemical, food, and pharmaceutical industries.
Stainless Steel 304L Welded pipes are produced by welding stainless steel sections, offering versatility and cost-effectiveness for structural and industrial uses, with low carbon content enhancing weldability.
Stainless Steel 304L Square pipes are precision-cut with a square cross-section, providing aesthetic appeal and structural support for architectural and construction projects, combining formability with excellent corrosion resistance.
304L pipes everywhere food’s being made—dairies, breweries, whatever. Super hygienic and tough. Chemical factories use them for tanks and piping that need to stay welded and leak-free, and pharma loves them for sterile lines. You’ll catch them in construction too, holding up buildings or adding some style to architecture. They’re even tucked away in exhaust systems and refinery setups, thanks to their chill attitude about heat and corrosion. To sum up: if your project needs pipes that can handle being welded, shoved into weird shapes, and still laugh at rust, 304L is where it’s at.
