304 is a kind of austenitic stainless steel ( Chromium is - Nickel stainless steel) 。 In the industry say 18/8 stainless steel 304, Cr content is 18% ( The minimum requirement) Ni content of 8% ( The minimum requirement) For the non-magnetic or weak magnetic ( Choose stainless steel judge whether magnetic alone is not enough) 。 304 quite useful including aircraft industry, dairy products and food processing industries. Have replied that 304 is a kitchen knife in front of the steel ( Tool steel) I beg to differ, make a kitchen knife bean estimates are ok, tool use is martensitic stainless steel ( 420440). 。 Performance: the tensile strength of sigma b ( MPa) ≥520; Yield strength sigma 0. 2 ( MPa) ≥205; Elongation delta (5 %) 40 or higher percentage reduction of area bits of
( %) ≥50; Hardness is 200 hv or less; 304 stainless steel is one of the most widely used chrome - Nickel stainless steel, the advantage is to have excellent corrosion and corrosion resistance and good resistance to intergranular corrosion performance, excellent hot and cold processing and forming performance, low temperature performance is good, good welding performance. ( And what material than) Is a low mechanical strength, cutting performance is poor;
