201 Stainless Steel Round Pipe Welded OD 9.5mm Thickness 0.5mm
Types of stainless steel
Some metals are plated with zinc, chromium, or nickel, for surface protection. In those cases, the benefits of the coating are lost once a scratch penetrates the plating. The chromium inside stainless steel provides more than this surface protection. It creates its passive film whenever it is exposed to air. Therefore, even if stainless is deeply scratched, the passivation layer will self-heal.
Types of stainless steel
There are several “families” of stainless steel. Each of these families has different proportions of iron, chromium, and carbon. Some have other elements, like nickel, molybdenum, manganese, or copper. The properties of these steels vary by content, making this a versatile group of alloys.
Stainless steel grades
Grades give a hint as to the family of a particular stainless steel. The most common grades are:
Ferritic stainless: 430, 444, 409, 430
Austenitic stainless: 304, 302, 303, 310, 316, 317, 321, 347
Martensitic stainless: 420, 431, 440, 416
Duplex stainless: 2304, 2205
