Overview

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

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 direct white enameling complies with ASTM standard A424: 2006.

EN_US-Engineering-Product-Cold-rolled-All Grades Surface aspectsTSE

Surface aspects

Surface quality according to ASTM A1008: 2013 and ASTM A568: 2011.

Surface quality class 1 (exposed):

The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality unexposed.

Surface quality class 2 (unexposed):

Defects that do not influence the formability or the application of surface coatings are permitted. These are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration.

Inspected side

As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.

Surface texture/roughness

Cold-rolled annealed and skin passed steel is available in several surface textures. All textures are available.
Unless specified otherwise, Tata Steel will supply ‘Regular matte’.

Description	Roughness µinch CLA
Commercial bright	≤ 10
H - dull	≤ 16
Light matte	≤ 36
Regular matte	24 - 76
Rough matte	50 - 100

^{Preservative oil}

The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.

Tata Steel offers a range of oiling levels:
Lightly oiled: 55 mg/ft² per side
Regular oiled: 110 mg/ft² per side

Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the unoiled condition.

^{Surface cleanliness}

Tata Steel can guarantee improved surface cleanliness on request for batch annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product.
Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%.

Cold-rolled annealed and skin passed steel is available in several surface textures. All textures are available.
Unless specified otherwise, Tata Steel will supply ‘Regular matte’.

Description	Roughness µinch CLA
Commercial bright	≤ 10
H - dull	≤ 16
Light matte	≤ 36
Regular matte	24 - 76
Rough matte	50 - 100

^{Preservative oil}

The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.

Tata Steel offers a range of oiling levels:
Lightly oiled: 55 mg/ft² per side
Regular oiled: 110 mg/ft² per side

Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the unoiled condition.

Properties

Mechanical properties

Steel for enamelling has the following typical mechanical properties (skin-passed) - these are measured transverse to the rolling direction.

Tata Steel Vitrostaal	Grade	Vitrostaal IF
ASTM A424: 2006	Grade	Type III
Yield strength	ksi	20
Tensile strength	ksi	41
Elongation	%	50
r_m-value		2.20
n-value		0.22

Min. elongation after fraction uses test piece length L₀= 2 inches.

Chemical composition

Tata Steel’s Vitrostaal complies with the following heat analysis with maximum values in weight percentages.

Tata Steel	Vitrostaal	Vitrostaal IF
ASTM A424: 2006	Grade	Type III
C	Max.	0.004

Cu ¹	Max.	0.040

^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 enamelling result.

Surface aspects

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