DIN 17441 Grade X6CrNb17 soft annealed (+A)
DIN 17441 Grade X6CrNb17 soft annealed (+A) introduction
Properties:
- ferritic steel with comparable corrosion properties like 1.4510
- resistant to water, steam, weak acids and brines and oxidising acids
- elevated resistance to crack corrosion in hot brines and water with chloride
- Ti-additives let decrease the danger of intergranular corrosion after welding
- a metallically clean surface is basic condition for a good corrosion resistance
- not high polishable
Application:
- for welded components in washing machines (base tanks)
- partly in chemical constructions (weak acids), food industry, breweries, dyeing and soap industry
- in arcitecture used for decorative construction units, where must be welded, e.g. for shelves, racks, interior arrangement elements
