  • Cold-rolled - Steel for enamelling (US Standard units)

    Tata Steel’s cold-rolled Vitrostaal family is designed specifically for enameling.

    Vitrostaal can deliver end product and process benefits including superb coating adhesion and reliable deep drawing. 

    Vitrostaal steel for enamelling

    Vitrostaal  cold-rolled steel for enamelling provides strong coating adhesion and reliable deep drawing. Vitrostaal LD grades provide improved resistance to carbon boiling.

    Applications include barbecues, bathroom furniture, heat-exchange panels, photovoltaic solar panels, white boards and wall panels.

    Overview

    Tata Steel has the correct steel grade for direct and conventional enameling and for one or two layered enameling.

    Vitrostaal II CS/DS

    For conventional enameling (two coat).

    Vitrostaal LD CS/DS

    The ultimate enameling steels made by Tata Steel, suitable for direct cover coat enameling. Decarburized in the steelplant, titanium free, cold-rolled and batch annealed, it has perfect adhesion of coating. Vitrostaal LD has improved resistance to carbon boiling and fish scaling.

    Vitrostaal IF

    Is a titanium stabilized enameling steel fit for all purposes when suitable enameling processes are used. It is especially suitable for applications where extra deep drawing is necessary.

     

    Applications

    • Barbecues
    • Bathtubs
    • Cookers and washing machines
    • Heat exchange panels (pore-free)
    • Photo Voltaic solar panels
    • Sinks
    • White boards and wall panels

     

    Relationship with standards

    Steel for enameling complies with ASTM standard A424: 2006.

     1. Copper concentration is dependent on phosphorous concentration.
    The elements P and Cu are kept within certain limits to ensure that the reactivity of the steel surface is as constant as possible.
    Under normal conditions this leads to a reproducible enameling result.

    2. The composition of Vitrostaal II differs sligthly from ASTM A424 Type II.

     

    Surface aspects

    Steel for enameling shall be supplied with a surface roughness between 24 and 76 CLA.

    Steel for direct enameling, Vitrostaal LD DS and Vitrostaal LD CS, normally has a checkerboard pattern. Vitrostaal IF normally has a stripe pattern. If a checkerboard or stripe pattern is not desired, this should be mentioned at time of ordering. If a different roughness is ordered, a checkerboard or stripe pattern is not possible.
