Nanoscale stainless steel




Stainless steel nanoparticles have been produced in the laboratory. These may have applications as additives for high-performance applications. For example, sulfurization, phosphorization, and nitridation treatments to produce nanoscale stainless steel based catalysts could enhance the electrocatalytic performance of stainless steel for water splitting.

Stainless steel : 276 is a group of iron-based alloys that contain a minimum of approximately 11% chromium,: 3 a composition that prevents the iron from rusting, as well as providing heat-resistant properties.: 3 Different types of stainless steel include the elements carbon (from 0.03% to greater than 1.00%), nitrogen, aluminium, silicon, sulfur, titanium, nickel, copper, selenium, niobium, and molybdenum.: 3 Specific types of stainless steel are often designated by a three-digit number, e.g., 304 stainless . Stainless steel's resistance to ferric oxide formation results from the presence of chromium in the alloy, which forms a passive film that protects the underlying material from corrosion attack, and can self-heal in the presence of oxygen.: 3 Corrosion resistance can be increased further, by: The addition of nitrogen also improves resistance to pitting corrosion and increases mechanical strength. Thus, there are numerous grades of stainless steel with varying chromium an...

( March 2020 ) (Learn how and when to remove this template message) The average carbon footprint of stainless steel (all grades, all countries) is estimated to be 2.90 kg of CO 2 per kg of stainless steel produced, of which 1.92 kg are emissions from raw materials (Cr, Ni, Mo); 0.54 kg from electricity and steam, and 0.44 kg are direct emissions (i.e., by the stainless steel plant). Note that stainless steel produced in countries that use cleaner sources of electricity (such as France, which uses nuclear energy) will have a lower carbon footprint. Ferritics without Ni will have a lower CO 2 footprint than austenitics with 8% Ni or more. Carbon footprint must not be the only sustainability-related factor for deciding the choice of materials: over any product life, maintenance, repairs or early end of l...
