Properties Required For Steel Plate To Be Enameled
Steel plate is the main raw material for steel enamel products, which accounts for more than 90% of the cost of enamel products. Some new enamel products factories often don’t know how to choose suitable enamel steel plates for production. This will easily lead to various of enamel defects in the production process of enamel products. In this article, enamel material manufacturer Nolifrit will talk to you about the properties required for steel plate to be enameled.
1. Formability
Metal plastic formability refers to the processing method to obtain certain shape, size and mechanical properties of parts or blanks through plastic deformation of metal materials under the action of external force.
2. Strength
Since the strength of the steel plate after enameling directly determines the use performance of the final enameled product, such as water heater liners and other pressure vessels, the strength of the steel plate after enameling has a great influence on the pressure resistance, so the strength decline of the steel plate after enameling should be as less as possible.
3. Anti fish-scale performance
Generally speaking, hot-rolled steel with the same composition and microstructure have worse fish-scale resistance than cold-rolled steel. Therefore, when selecting hot-rolled steel sheets as enamel substrates, hot-rolled steel sheets with better fish-scale resistance must be selected. At the same time, it is necessary to do a good job of supporting programs against fish-scale defect.
4. Adhesion performance
The hot-rolled steel plate must be pickled or shot blasted to completely remove the oxide scale on the surface. The surface of the steel plate after the above-mentioned treatment has a larger surface roughness than the ordinary cold-rolled plate, which is beneficial to improve the adhesion performance.
5. Anti-pinhole defects
Decarburized steel is characterized by extremely low carbon content. The significant advantage of this type of steel for enamel is that the probability of pinhole defects is small. Decarburized steel is mainly used in a direct-on enamel process, such as making enamel home appliance panels and enamel heat exchange elements.
The above are some of the main properties that enamel grade steel sheets need to have. Nolifrit reminds everyone that when choosing enamel raw materials, you can determine whether you need hot-rolled steel, cold-rolled steel or decarburized steel according to the requirements and cost of the specific product. Hope this introduction can bring you a little help.
