Further, 304 stainless steel after cold working to the martensite transformation structure also, the greater the degree of cold deformation, more martensite transformation, the greater the magnetic steel. Like steel batch numbers, production Φ76 Zaozhuang stainless steel tube combination screws, no significant magnetic induction, production Φ9.5 tube. Ling bending deformation due to the larger number of magnetic induction is obviously a combination of stainless steel screws, square and rectangular tube production due to deformation than the combination of stainless steel pipe large Tai'an screws, especially knuckle part, more intense magnetic distortion is more evident. To completely eliminate the magnetic steel above 304 causes, can be opened to restore stability austenite at high temperature solution treatment, thereby erasing magnetic. Stainless steel hex screws are stainless steel fasteners series, the most common kind, and nuts match, use of the product has high anti-corrosion requirements and high surface finish requirements of local, stainless steel hex screws and generally the whole tooth two kinds of semi-teeth, and dental products are divided into semi-thick shaft and a half teeth and thin rod and a half teeth. Production of stainless steel hex screws material commonly used two kinds of SUS304 and SUS316. Grade identified as A2-70 and A4-70. Currently in circulation are mostly stainless steel hex screw the whole tooth.
