External causes produce stainless steel screw locking phenomenon: the stainless steel bolts are not carefully cleaned off the production line or saved in the process, Yantai stainless steel slotted screws used directly in the production line and result in product thread has locked the physical properties of the phenomenon of foreign body occurs The physical properties of stainless steel and carbon steel data comparison, Zibo stainless steel slotted screws, slightly higher than the density of steel ferritic and martensitic stainless steel, stainless steel slotted screw Qingdao, but slightly lower than the austenitic stainless steel; resistivity Press carbon steel, ferritic, martensitic and austenitic stainless steel Sort Ascending; linear expansion coefficient of the sort is similar, austenitic stainless steel and carbon steel up to a minimum; carbon steel, ferritic and martensitic magnetic stainless steel, stainless steel slotted screw, austenitic stainless steel non-magnetic, but it generates a work hardening martensitic phase transformation will generate magnetism, heat treatment method can be used to eliminate this martensite and restore its non-magnetic. Stainless steel screws selection principles: choice of stainless steel materials, mainly from the following five aspects to consider. 1, stainless steel screw material in mechanical properties, particularly strength requirements; 2, do work conditions on the material aspects of corrosion resistance requirements; 3, the working temperature of the material heat resistance (high-temperature strength, oxidation resistance ) requirements; 4, the production process for material processing performance requirements; 5, other aspects, such as weight, price, purchase, and many other factors must be considered stainless steel slotted screw _ _ Linyi Jinan Road ground by a stainless steel slotted screws Jinan Daoqin Trading Limited.
