Detail

316L modified (724L)

Introduction

316L modified, also known as 316L urea  grade has been created for urea plant applications.

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.

Density : 7.9 kg/m3

Character

The   alloy  is  designed   for  urea  applications  (low   carbon  and  silicon   contents).

The 316L Modified grade can be welded with most of the welding  processes: TIG, Plasma, MIG welding, as well as SMAW, SAW or FCAW processes.  The alloy is sensitive to hot cracking phenomenon due to its fully austenitic  microstructure. Weld should be performed in order to obtain extra-low ferrite  contents, no carbide or nitrides precipitations, low silicon contents as well  as no intermetallic phase precipitations. Higher manganese content products  should be considered.

Application

The UREA 316L Modified grade is  designed for the fabrication of lining interiors in Urea units or  complementary products (pipes, fittings...).  

The alloy is not designed for nitric  acid applications.
