Stainless & Corrosion-Resistant Stahl — Engineering Referenz
Stainless steels sind defined durch ihre chromium content (minimum 10.5%), welche forms ein self-healing passive layer von chromium oxide das resists corrosion. Grades sind classified durch microstructure: austenitic (300 series), ferritic (400 series), martensitic, und duplex.

Für welded stainless fabrications, specify der niedrig-carbon variant (304L, 316L) zu prevent chromium carbide precipitation bei grain boundaries, welche causes intergranular corrosion (weld decay).
