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(ju)AISI的(de)牌(pai)號表示方法,即:2-Cr-Ni-Mn系;3-Cr-Ni系;4-Cr系(6-沉(chen)淀硬化系)。
日(ri)本獨特的牌(pai)(pai)號(hao),采用類似的AISI牌(pai)(pai)號(hao)在其(qi)后加J1、J2來(lai)表(biao)示。舉例:SUS201、SUS304、SUS304J1。
按照鋼(gang)(gang)(gang)材(cai)的形狀、用(yong)(yong)(yong)途和(he)制造方(fang)法(fa)等,當需要(yao)用(yong)(yong)(yong)代號表(biao)示時,在牌號后面加(jia)上相應(ying)號,如下(xia)所示:B:棒材(cai);CB:冷(leng)加(jia)工(gong)棒材(cai);HP:熱(re)軋鋼(gang)(gang)(gang)板(ban);CP:冷(leng)軋鋼(gang)(gang)(gang)板(ban);HS:熱(re)軋鋼(gang)(gang)(gang)帶(dai);CS:冷(leng)軋鋼(gang)(gang)(gang)帶(dai);CSP:彈簧用(yong)(yong)(yong)鋼(gang)(gang)(gang)帶(dai);WR:線(xian)材(cai);Y:焊接用(yong)(yong)(yong)線(xian)材(cai);W:鋼(gang)(gang)(gang)絲(si);WP:彈簧用(yong)(yong)(yong)鋼(gang)(gang)(gang)絲(si);WS:冷(leng)鐓用(yong)(yong)(yong)鋼(gang)(gang)(gang)絲(si);HA:熱(re)軋角(jiao)鋼(gang)(gang)(gang);CA:冷(leng)軋角(jiao)鋼(gang)(gang)(gang);TB:鍋爐及熱(re)交(jiao)換器用(yong)(yong)(yong)鋼(gang)(gang)(gang)管(guan)(guan);TPY:配管(guan)(guan)用(yong)(yong)(yong)電焊大口徑鋼(gang)(gang)(gang)管(guan)(guan);TP:配管(guan)(guan)用(yong)(yong)(yong)鋼(gang)(gang)(gang)管(guan)(guan);TPD:一般配管(guan)(guan)用(yong)(yong)(yong)鋼(gang)(gang)(gang)管(guan)(guan)。舉(ju)例:SUS304-B、SUS304-WR、SUS304-HP。
