1.4435 – 316L (Mod) UG
Available from stock !
The UREA™ 316L grade has been specially developed for urea plant applications.
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.
The alloy is designed for improved corrosion resistance properties in urea - carbonate environments.

Typical maximum corrosion results required following different specifications after Huey tests (ASTM A262 C - five periods of 48 h.) are : maximum weight loss lower than 3,3 μm/48 h (130 mg/dm² per 24 h.), with a maximum depth for microcracks of 200 μm in the long direction and 70 μm in the transverse direction. The UREA™ 316L grade behaves much better than those maximum values.
The UREA™ 316L grade is designed for the fabrication of lining interiors in urea units or complementary products (pipes, fittings...) .
