8. 1 non magnetizable chromed steels Chromed steels have favourable thermo technical characteristics In fact they have less of a tendency to warp due to the effect of heat Chrome nickel steels instead have good corrosion resistance fea tures Stainless steel corrosion resistance is given by an inactive coat that builds up on the surface by coming into contact with oxygen The oxygen in the air is already enough to build up the inactive coat that allows automatic removal of anomalies and damage due to mechanical actions The inactive coat builds up or re builds up faster if the steel comes in contact with running water containing oxygen A more powerful effect is given by oxidative acids nitric acid oxalic acid These acids are used if the steel has undergone strong chemi cal stresses hence generally losing its inactive coat The inactive layer can be chemically damaged or jeopardized by reducing agents oxygen consumption if they come in contact with the steel concentrated or at high temperatures These active sub stances include for instance saline and sulphurous substances chlorides salts concentrated spices such as mustard vinegar essences soup cubes kitchen salt solutions etc More damage can be caused by outside rust i e from other components tools or incipient rust iron particles i e file dust contact with non ferrous metals element build up lack of oxygen i e no air inlet w
