日本JIS不銹鋼材料標準的牌號表示方法為SUS＋數字編號。其中，S：鋼；U：用途；S：不銹；數字編號基本采用美國AISI的牌號表示方法。

 根據AISI的牌號表示方法，即：2-Cr-Ni-Mn系(xi)；3-Cr-Ni系(xi)；4-Cr系(xi)（6-沉淀硬化系(xi)）。

 日本獨特的(de)牌號，采用類似的(de)AISI牌號在其(qi)后加J1、J2來表示。舉例：SUS201、SUS304、SUS304J1。

 按照(zhao)鋼(gang)(gang)(gang)(gang)材(cai)的形狀、用(yong)(yong)(yong)(yong)途和制(zhi)造方(fang)法(fa)等，當需(xu)要用(yong)(yong)(yong)(yong)代(dai)號(hao)(hao)表示(shi)時(shi)，在牌號(hao)(hao)后面加(jia)上相應號(hao)(hao)，如下所示(shi)：B：棒材(cai)；CB：冷(leng)加(jia)工棒材(cai)；HP：熱(re)軋(ya)鋼(gang)(gang)(gang)(gang)板；CP：冷(leng)軋(ya)鋼(gang)(gang)(gang)(gang)板；HS：熱(re)軋(ya)鋼(gang)(gang)(gang)(gang)帶(dai)(dai)；CS：冷(leng)軋(ya)鋼(gang)(gang)(gang)(gang)帶(dai)(dai)；CSP：彈(dan)(dan)簧(huang)(huang)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)帶(dai)(dai)；WR：線(xian)材(cai)；Y：焊接(jie)用(yong)(yong)(yong)(yong)線(xian)材(cai)；W：鋼(gang)(gang)(gang)(gang)絲(si)；WP：彈(dan)(dan)簧(huang)(huang)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)絲(si)；WS：冷(leng)鐓用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)絲(si)；HA：熱(re)軋(ya)角鋼(gang)(gang)(gang)(gang)；CA：冷(leng)軋(ya)角鋼(gang)(gang)(gang)(gang)；TB：鍋爐及熱(re)交換器用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)管(guan)；TPY：配管(guan)用(yong)(yong)(yong)(yong)電焊大口(kou)徑鋼(gang)(gang)(gang)(gang)管(guan)；TP：配管(guan)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)管(guan)；TPD：一般配管(guan)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)管(guan)。舉例：SUS304-B、SUS304-WR、SUS304-HP。
