New and improved thicker 321 stainless material!
New for May 2014, this header now has 2mm thick pipes and 3mm thick collectors of 321 stainless steel. The preferred material for high temp applications, 321 stainless steel offers extreme resistance to high temperatures. Used extensively for turbo and aircraft applications, 321 stainless steel withstands temperatures in excess of 1650 degrees without losing its structural integrity. Flanges are 12mm 304 stainless steel.
