Stainless steel cold-rolled strip is an important material used in the manufacture of recording heads. Recording heads are used to convert electrical signals generated by electronic equipment into magnetic signals and vice versa. They are used in video, audio and data recording and playback systems, and are part of the key components that make modern digital recording and playback equipment possible.
Cold-rolled stainless steel strip is used for recording heads due to its combination of strength, corrosion resistance, and ease of machinability. Cold-rolled stainless steel strip typically available in thickness from 0.1 to 0.5mm and widths from 12.7 to 115mm, and is used for recording head components including magnetic core, flux gap assembly, return guide, return pole and shield.
As defined by YB/T085-1996, cold-rolled stainless steel strip should be made from the highest quality stainless steel materials, such as 304 and 316L grade steel. It should be cold-rolled to a precise thickness and straightness to ensure fewer tolerances on magnetic components. Its good magnetic properties should provide high permeability and inductance, which will help to optimise the efficiency of the recording head. It should also have high tensile strength and excellent wear resistance, to protect the recording head components from damage during operation.
To ensure quality control, cold-rolled stainless steel strip should undergo strict manufacturing processes, starting with hot rolling and batch annealing to produce the raw hot rolled material. This should be followed by pickling to remove surface scales and inconsistencies, before the material is cold rolled to the finished thickness and quality. During the cold rolling process, intermediate annealing is performed to ensure elongation, tensile strength and corrosion resistance properties, and a final annealing and pickling is carried out before the material is cut for production.
In conclusion, cold-rolled stainless steel strip is a key material for producing recording heads, due to its strength, corrosion resistance and machinability. To ensure the best performance and durability of the recording head, it is important to select the highest quality materials, such as 304 and 316L grade steel, and also to use a manufacturer that has the capabilities to employ strict manufacturing processes and quality control measures.
