316L Stainless Steel Bar & Tube Sheet
Низкоуглеродистая аустенитная нержавеющая сталь хромоникельмолибденовая.
316Л, the low carbon version of 316 stainless steel, is immune to grain boundary carbide precipitation (sensitisation). This makes it suited to use in heavy gauge (over about 6mm) welded components.
Stainless steel types 1.4401 and 1.4404 are also known as grades 316 and 316L respectively. Grade 316 is an austenitic grade second only to 304 in commercial importance. 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.
