SS Sheet EN1.4404,4432/36 Width >=2M

As standard, cold-rolled and hot-rolled stainless-steel sheets are stocked in widths up to and including 1500 mm. However, it can sometimes be advantageous with wider sheet and for this reason, Tibnor stocks a range of cold-rolled (with surface finish 2B) and hot rolled (surface finish 1D) sheet with width 2000 mm. 

The austenitic steel with designation 1.4404 contains molybdenum in addition to chromium and nickel. The difference against 1.4301/1.4307 apart from the presence of molybdenum is that the nickel content is greater. 1.4432 and 1.4436 have even higher molybdenum content than 1.4404. This type of stainless steel alloyed with molybdenum is often referred to as acid resistant which is to some degree a misnomer since the materials resist attack only by weak acids. In terms of strength, all three grades are more or less equivalent to the lower alloyed stainless steels 1.4301/1.4307. 

Flat formats of all these grades are standardised in EN 10088-2. This standard covers cold-finished strip with thicknesses ≤ 8 mm and hot-finished strip with thicknesses up to and including 13.5 mm. 

The presence of molybdenum along with chromium renders 1.4404, 1.4432 and 1.4436 resistant to corrosion in weak acids and water containing chlorides so long as the chloride concentration is not too high; an example of an environment where the steels work well is salt-laden coastal atmosphere. These materials are also used extensively for equipment in professional kitchens and for large-scale food processing. 

The formability of hot- or cold-finished sheets in all three grades is in most cold-forming operations excellent and often equivalent to that of corresponding carbon steel. In addition, weldability is very good and there are seldom any issues in fabrication of welded structures.
