Abstract

The invention provides a stainless steel heating plate and a preparation method thereof. The stainless steel heating plate comprises, by weight: C of not more than 0.01%, Si of not more than 1.00%, Mnof not more than 1.00%, Mn of not more than 1.00%, P of not more than 0.05%, S of not more than 0.005%, Ni of not more than 0.01%, Cr of not more than 20.5%, N of not more than 0.01%, Al of 4.80%-5.20%, and the balance being Fe and inevitable sundries. According to the invention, through improvement of a formula and a technology and through limiting of weight percentages of Al and Cr in total rawmaterials, material uniformity, electric conductivity and ductility of a stainless steel sheet are improved effectively; through a finish rolling method, the heating plate can be processed to the thickness of 30 mu m, and processing accuracy is ensured, so that the problems that an existing stainless steel sheet is uneven in heating, slow in heating and high in power consumption are solved; and through limiting of material proportions, the service life of the stainless steel heating plat is greatly prolonged, and degradation courses of own strength and tension resistance are delayed

Description

technical field [0001] The invention relates to the technical field of stainless steel heating sheets, in particular to a stainless steel heating sheet and a preparation method thereof. Background technique [0002] Stainless steel is the abbreviation of stainless acid-resistant steel, and the steel grades that are resistant to weak corrosive media such as air, steam, water, or have stainless properties are called stainless steel; The steel type is called acid-resistant steel. [0003] Due to the difference in chemical composition of the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel is generally stainless. The term "stainless steel" does not simply refer to one kind of stainless steel, but refers to more than one hundred kinds of industrial stainless steels, and each developed stainless steel has good performance in its specific application field. The key to success...
