Other Designations Equivalent materials to grade 444 stainless steel are:ASTM A176 SAE 51444 Application (usage ):papermaking equipment,pharmaceutical Corrosion of Stainless Steel by Urea at High TemperatureThe relationship between aqueous urea solution, its thermal decomposition products and the corrosion mechanism of stainless steel is studied by FTIR spectroscopy, SEM and stereo microscopy. The corroded steel samples, together with deposits, were obtained from the injection of aqueous urea solution on the steel plate at high temperatures.
Steel pipes and steel plates are usually used as constituent members in a urea manufacturing plant. These steel pipes and steel plates are produced by hot working such as forging, extrusion or rolling, and with or without subsequent cold working.

Dec 10, 2020 · a) R p0.2 and R p1.0 correspond to 0.2% offset and 1.0% offset yield strength, respectively. b) Based on L 0 = 5.65 ÖS 0 where L 0 is the original gauge length and S 0 the original cross-sectional area. c) Requirements according to EN 1.4466, W.-Nr. 1.4465 and AFNOR can be fulfilled on request. Impact strength. Due to its austenitic microstructure, Sandvik 2RE69 has very good UREA 316L - IndusteelThe UREA 316L grade is a fully austenitic stainless steel which ferrite content is guaranteed less than 0.5% after solution annealing heat treatment 1120 - 1180°C (2048 - 2156°F) / water quenched. The carbon content is kept low while the steel making is optimised in order to improve the cleanliness properties of the steel. The alloy is designed for urea applications.
