Make stainless steel screws threaded nut is screwed, Qingdao 316 stainless steel screws, or a threaded hole in the product after joining to produce superior clamping action. Play super good locking effect. The physical properties of the physical properties of stainless steel and carbon steel comparison of the data, 316 stainless steel screws, slightly higher than the density of steel ferritic and martensitic stainless steel, but slightly lower than the austenitic stainless steel; resistivity press steel, ferritic size, 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 stainless steel magnetic, Yantai 316 stainless steel screws, 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.
