展開全部304不銹鋼材質(zhì)硬度：≤187HB；≤90HRB；≤200HV。304不銹鋼是不銹鋼中常見的一種材質(zhì)，密度為g/cm3，業(yè)內(nèi)也叫做18/8不銹鋼。耐高溫800度，具有加工性能好，韌性高的特點(diǎn)，***使用于工業(yè)和家具裝飾行業(yè)和食品醫(yī)療行業(yè)。市場上常見的標(biāo)示方法中有00Cr19Ni10，SUS304，其中00Cr19Ni10一般表示國標(biāo)標(biāo)準(zhǔn)生產(chǎn)，一般表示ASTM標(biāo)準(zhǔn)生產(chǎn)，SUS304表示日標(biāo)標(biāo)準(zhǔn)生產(chǎn)。304是一種通用性的不銹鋼，硬度機(jī)廠家定制，它***地用于制作要求良好綜合性能（耐腐蝕和成型性）的設(shè)備和機(jī)件。為了保持不銹鋼所固有的耐腐蝕性，硬度機(jī)廠家定制，鋼必須含有18%以上的鉻,8%以上的鎳含量。304不銹鋼是按照美國ASTM標(biāo)準(zhǔn)生產(chǎn)出來的不銹鋼的一個(gè)牌號(hào)。拓展資料：組成元素：在空氣中或化學(xué)腐蝕介質(zhì)中能夠抵抗腐蝕的一種高合金鋼，不銹鋼是具有美觀的表面和耐腐蝕性能好，不必經(jīng)過鍍色等表面處理，而發(fā)揮不銹鋼所固有的表面性能,使用于多方面的鋼鐵的一種，通常稱為不銹鋼。代表性能的有13鉻鋼，18-8鉻鎳鋼等高合金鋼。不銹鋼防銹的機(jī)理是合金元素形成致密氧化膜，硬度機(jī)廠家定制，隔絕氧接觸，阻止繼續(xù)氧化。所以不銹鋼并不是“不銹”。304材料出現(xiàn)生銹現(xiàn)象，可能有以下幾個(gè)原因：1.使用環(huán)境中存在氯離子。氯離子***存在。金屬硬度測量zui早由雷奧姆爾提出硬度定義，表示材料抵抗硬物體壓入其表面的能力。硬度機(jī)廠家定制</p><div
