High Quality 316LMod Stainless Steel Round Bar specifically engineered for urea plant applications. Available in diameters from 6mm to 250mm as hot rolled or forged stainless steel bars.
Product Overview
UREA 316L Modified grade has been specially developed for urea plant applications. This 316L modified stainless steel features extra-low silicon content and substantially higher molybdenum contents for superior performance in demanding environments.
The low carbon content, combined with well-balanced chemistry (low silicon and nickel content close to 14%) makes the alloy fully austenitic and free of intermetallic phase precipitations. The ferrite level is maintained under 0.5% in solution annealing and water quenched conditions.
This alloy is specifically designed for improved corrosion resistance properties in urea-carbonate environments, making it ideal for industrial applications requiring exceptional durability.
Hot forming should be carried out in a temperature range of 1200-950°C (2732-1742°F) after uniform heat treatment. Final full annealing temperature is required at 1120-1180°C (2048-2156°F) followed by water quenching to obtain the requested microstructure.
Cold Forming
Due to its fully austenitic microstructure, the alloy can be cold formed without problems. The higher molybdenum content and cold hardening behavior may require more powerful equipment than standard 304 stainless steel.
Pickling
UREA Modified grade must be used in as-pickled and passivated conditions. Pickling treatment can be performed with nitro-hydrofluoric acid bath or H2SO4-HF pickling bath at specified temperatures and durations.
Welding
Alloy UREA Modified can be welded with most processes including TIG, Plasma, MIG, SMAW, SAW, or FCAW. The alloy is sensitive to hot cracking due to its fully austenitic microstructure. Use basic coated electrodes or fluxes, limit heat input to 1.5 kJ/mm, and maintain interpass temperature below 150°C (302°F).
Corrosion Performance
Typical corrosion test results in Huey test solution (ASTM A262-C) show maximum weight loss of 3.3 m/48h - 0.54 g/m h with selective attack lower than 200 m.
