SUS439 Stainless Steel Welded Pipe
439 stainless steel is an enhanced ferritic material based on the 430 grade, with reduced carbon content and added stabilizing elements like titanium. This formulation significantly improves intergranular corrosion resistance, formability, and weldability. While its elongation is approximately 30% (lower than 304 grade), it offers comparable strength and corrosion resistance, with superior performance compared to 200 series materials.
