日本JIS不(bu)銹(xiu)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(de)牌號表示(shi)方法(fa)，即：2-Cr-Ni-Mn系；3-Cr-Ni系；4-Cr系（6-沉淀(dian)硬化系）。

 日本獨特的牌號，采用類似的AISI牌號在其后(hou)加(jia)J1、J2來表示。舉例：SUS201、SUS304、SUS304J1。

 按照鋼(gang)(gang)(gang)(gang)(gang)材(cai)的形(xing)狀(zhuang)、用(yong)(yong)(yong)(yong)(yong)(yong)途和制造方法等，當需要(yao)用(yong)(yong)(yong)(yong)(yong)(yong)代號(hao)表示(shi)時，在(zai)牌號(hao)后面(mian)加上相應(ying)號(hao)，如(ru)下(xia)所(suo)示(shi)：B：棒材(cai)；CB：冷(leng)加工棒材(cai)；HP：熱(re)軋(ya)鋼(gang)(gang)(gang)(gang)(gang)板(ban)；CP：冷(leng)軋(ya)鋼(gang)(gang)(gang)(gang)(gang)板(ban)；HS：熱(re)軋(ya)鋼(gang)(gang)(gang)(gang)(gang)帶(dai)(dai)；CS：冷(leng)軋(ya)鋼(gang)(gang)(gang)(gang)(gang)帶(dai)(dai)；CSP：彈簧用(yong)(yong)(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)(gang)帶(dai)(dai)；WR：線(xian)材(cai)；Y：焊(han)接用(yong)(yong)(yong)(yong)(yong)(yong)線(xian)材(cai)；W：鋼(gang)(gang)(gang)(gang)(gang)絲；WP：彈簧用(yong)(yong)(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)(gang)絲；WS：冷(leng)鐓用(yong)(yong)(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)(gang)絲；HA：熱(re)軋(ya)角鋼(gang)(gang)(gang)(gang)(gang)；CA：冷(leng)軋(ya)角鋼(gang)(gang)(gang)(gang)(gang)；TB：鍋爐及熱(re)交換器用(yong)(yong)(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)(gang)管(guan)；TPY：配管(guan)用(yong)(yong)(yong)(yong)(yong)(yong)電焊(han)大(da)口徑鋼(gang)(gang)(gang)(gang)(gang)管(guan)；TP：配管(guan)用(yong)(yong)(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)(gang)管(guan)；TPD：一(yi)般配管(guan)用(yong)(yong)(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)(gang)管(guan)。舉例：SUS304-B、SUS304-WR、SUS304-HP。
