Ferritic stainless steels (ferritic structure) are iron-chromium-carbon alloys in which the chromium values are between 16 and 28%.
The mechanical characteristics of these steels can be increased to a limited extent by subjecting them to the same cold deformation processes which bring about work hardening (drawing, rolling, etc.).
Their wear to resistance is considered to be good.
These stainless steels are the ones that are least suitable for use at low temperatures.
Weldability of conventional ferritic stainless steel is mediocre. Resistance welding (spot welding and roller welding) is the most suitable welding process.
Weldability improves when moving to other structural, stabilized types with low interstitial content.
They are well suited for cold deformation.<\/p>\n

TECHNICAL SPECIFICATIONS<\/h4>\n

Ferritic stainless steels are iron-chromium-carbon alloys in which the chromium values are between 16 and 28%.
\nIn addition, depending on their end use, there are other elements such as molybdenum and nickel.
\nThey have a ferritic structure.<\/p>\n

The mechanical characteristics of these steels can be increased to a limited extent by subjecting them to the same cold deformation processes which bring about work hardening (drawing, rolling, etc.).
\nTheir wear to resistance is considered to be good. <\/p>\n

RESILIENCE <\/h4>\n

Their toughness at temperatures below ambient shows that these stainless steels are the ones that are least suitable for use at low temperatures. <\/p>\n

They have an abrupt drop of resilience as soon as there is a change of the ambient temperature. <\/p>\n

WELDABILITY<\/h4>\n

Weldability of conventional ferritic stainless steel is mediocre. Resistance welding (spot welding and roller welding) is the most suitable welding process.
\nWeldability improves when moving to other structural, stabilized types with low interstitial content. <\/p>\n

PROCESSABILITY<\/h4>\n

Good processability for cold deformation. Their resulphurised versions guarantee machinability rather well.

SURFACE CHARACTERISTICS<\/h3>\n

[\/et_pb_text][et_pb_text _builder_version=”4.4.8″ header_4_font=”|||on|||||” header_4_text_color=”#002a5a”]<\/p>\n

Standard rolled finish<\/h3>\n

These surface finishes are attained on the steel product directly at the steel mill during rolling and the subsequent treatment cycles.
The various finishes with codes provided for by the AISI standard follow.<\/p>\n

Finish no. 0<\/strong>
Only hot-rolled, followed by heat treatment.<\/p>\n

Finish no. 1<\/strong>
It is the typical finish of hot-rolled sheets. It can be attained by hot rolling, followed by annealing, recrystallization or solution annealing according to the martensitic, ferritic and austenitic types, lastly followed by pickling in one or more baths in an acid solution to descale.
It has a matt silver grey appearance and a rough texture.<\/p>\n

Finish no. 2D (D = dull, matt)<\/strong>
It is the finish attained by cold rolling with a reduction of thickness by at least 20% of already hot rolled, heat treated and pickled strips with finish no. 1. Cold rolling is followed by a treatment to soften the steel (annealing, recrystallization or solution annealing according to the types of stainless steels) and then pickling.
The surface is not reflective yet, however it is smoother than finish no. 1 because of the cold rolling it has undergone. In addition, thickness is much more constant with more restricted tolerances.
It has a silver grey, matt and smooth appearance.<\/p>\n

Finish no. 2B (B = bright)<\/strong>
This finish is attained on strips with a no. 2D finish by a skin pass process with polished rolls. It has a bright silver grey appearance and it is the most widespread finish for cold rolled flat products.<\/p>\n

Finish BA (BA = bright annealed) <\/strong>
It is the finish of cold rolled products attained by heat annealing, recrystallization or solution annealing according to the cases, in a controlled atmosphere (basically dissociated ammonia), after rolling and subsequent roughing. Because of the particular thermal treatment, the material does not become oxidized, pickling is therefore not necessary, and it maintains a very bright and reflective look which is typical of cold rolled products. As the formation of oxides is prevented, dechromatization does not take place which is subsequently highlighted by pickling. Any possible alteration of chromium, the most important of the alloy elements, does not take place accordingly, and its surface concentration hence remains equal to the one inside the material.<\/p>\n

SURFACE FINISH<\/h4>\n

Surface quality of stainless steels is extremely important, not only for aesthetic purposes, but, most of all, as regards the intrinsic resistance of the steel in respect to internal corrosion.
We can basically say that resistance to corrosion will be greater when surface smoothness is greater; in other words, the less rough the surface of the stainless steel element is, greater its resistance to corrosion is.
There are rules which codify a certain number of finishes defined \u201cstandard\u201d, at least for the most widespread types of products.
They can be divided into three types:<\/p>\n

    \n
  • Standard ground finish<\/li>\n
  • Scotch Brite finish<\/li>\n
  • Anti fingerprint polishing<\/li>\n<\/ul>\n

    Standard ground finish <\/strong>
    These finishes are carried out on stainless steels with the use of abrasives of suitable grain size. Besides the standard finishes provided for by the standard there are also non standard finishes, not classified by standards but implemented for specific purposes.
    The descriptions for the various finishes codified by the AISI standard and Gavinox finishes are found below.<\/p>\n

    Scotch Brite brushing <\/strong>
    This kind of surface finish is uni-directional and attained by brushing.
    Fibre abrasive belts are used to make light incisions\/etches on the surface of the steel.
    Brushing is done with special coarse, medium, fine or extra-fine grit brushes depending on the ultimate outcome required.<\/p>\n

    Satin finish<\/strong>
    This kind of surface finish is uni-directional and attained by grinding with abrasive rolls. These rolls produce incisions\/etches on the surface of the steel.
    Special abrasive rolls of various grains are used for a satin finish depending on the final desirable outcome.<\/p>\n

    Duplo<\/strong>
    A double finish (duplo) attained by first satin finishing and then brushing to reduce roughness of the surface.<\/p>\n

      CORROSION RESISTANCE<\/h3>\n

      [\/et_pb_text][et_pb_text _builder_version=”4.4.8″ header_4_font=”|||on|||||” header_4_text_color=”#002a5a”]<\/p>\n

      Corrosion resistance of these steels rises with the increase of chromium content in the alloy, especially as regards resistance to heat oxidation (up to 1200\u00b0C).
      They are essentially immune to cracking due to stress corrosion induced by chlorides, although their resistance to corrosion is not as good as the one of austenitic types.
      They cannot be used for cryogenic applications as their microstructure is ferritic (they become fragile at low temperatures).
      Their resistance to pitting increases by adding molybdenum, and their resistance under stress is considered good.
      Good resistance to corrosion due to weather conditions especially after high-luster polishing.
      AISI 409: it is also called \u201cmuffler grade\u201d (the type for mufflers) and often used for catalytic exhausts.
      ASI 430: it has good corrosion resistance characteristics both at ambient temperature, and at higher temperatures (not greater than 700\u00b0C however) and is heat resistant to dry sulphurous gases.
      It has acceptable resistance to pitting and is good under stress.<\/p>\n
