Description and Application: 

316l mod is modified 316l, an improved 316l, which is specially used in the urea industry, so it is called urea grade 316l.

The main difference from 316l is the chemical composition. The purpose of adjusting the composition is to fully suppress

the ferrite content in the steel and obtain a full austenite structure as much as possible, so as to improve the intergranular

corrosion resistance and selective corrosion resistance of the steel. Both urea grade stainless steels are subject to Hugh’s

test and selective corrosion test. The test conditions are very harsh, and it is difficult for ordinary stainless steel to pass.

The chemical composition of 316mod and 316l is not very different. 316mod must pass the Huey test. During the 48-hour

boiling corrosion test, the corrosion value of 5 samples is not less than 0.54gr/m2hr (3.3 microns/48 hours). )
