1.4401 (316)

A chromium-nickel-molybdenum austenitic stainless steel.

tainless steel types 1.4401 (also known as grade 316) is an austenitic grade second only to 304 in commercial importance. It has similar mechanical properties to 304 but is stronger at elevated temperatures.

316 stainless steel contains an addition of molybdenum that gives it improved corrosion resistance. This is particularly apparent for pitting and crevice corrosion in chloride environments. The austenitic structure of 316 stainless steel gives excellent toughness, even at cryogenic temperatures.

Property data given in this document is typical for bar and section products covered by EN standards. ASTM, EN or other standards may cover all products sold. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.

Quarto Plate is hot rolled plate over 12mm thick that has not been coiled during production. CPP is Continuously Produced Plate up to 12mm thick that has been coiled during rolling. Sheet is Cold Rolled.

Property data given in this document is typical for flat rolled products covered by EN standards. ASTM, EN or other standards may cover all products sold. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.
