About 316LMod Urea Class Stainless Steel
What is 316LMod Urea Class Stainless Steel?
316LMod urea class stainless steel has been specially developed for urea plant industry.
It is a 316L modified stainless steel with extra-low silicon content and substantial higher molybdenum contents.
The low carbon content, combined with a well balanced chemistry (low silicon and nickel content close to 14%) makes the alloy fully austenitic, free of intermetallic phase precipitations. The ferrite level is kept under 0.5% in the solution annealing and water quenched conditions.
This alloy is designed for improved corrosion resistance properties in Urea- carbonate environments.
