Overview
304/304L and 316/316L are the most widely produced seamless pipe grades at TOKO TECH. We maintain extensive inventory in standard sizes and wall thicknesses from SCH 5S to XXS. Our cold-pilgered seamless pipes deliver superior surface finish and dimensional accuracy compared to hot-finished alternatives. 316L's molybdenum addition provides significantly improved pitting resistance for chloride-containing environments.
