Finnish Langh Group Cargo Solutions has chosen Outokumpu’s new high-chromium austenitic steel grade Outokumpu 316plusTM (Outokumpu 4420) in cold worked condition for their special transportation containers. The container’s floor and walls are made of Outokumpu stainless steel due to strict requirements for wear and corrosion resistance. 316plus enables transportation of aggressive and sharp bulk materials. The properties of 316plus allow thinner wall thickness resulting in lower overall weight of the container.

Says Markku Yli-Kahri from Langh Group Cargo Solutions: “The special containers can be used for transporting various goods in ships, trains or trucks. We have built these containers with wear-resistant carbon steels before, but the combination of corrosion and wear-resistance of 316plus is better. I was excited to find out about Outokumpu 316plus as it offered even better material performance than 316(L), but the price was lower. In addition handling and welding of the 316plus was similar to standard grades and therefore we could use familiar tools and welding techniques in construction.”
Outokumpu 316plus is a unique product developed by Outokumpu that provides a competitive alternative for 316(L). 316plus contains less nickel and molybdenum and the grade has higher strength than 316(L) even in annealed condition due to higher nitrogen alloying.
