不(bu)銹鋼(gang)(gang)材的(de)(de)表面(mian)(mian)(mian)(mian)質(zhi)量實際(ji)(ji)上決定(ding)(ding)(ding)于(yu)鋼(gang)(gang)材表面(mian)(mian)(mian)(mian)加工(gong)的(de)(de)要(yao)求(qiu)(qiu)(qiu)。除我國(guo)標(biao)(biao)準外(wai)，國(guo)外(wai)標(biao)(biao)準對(dui)表面(mian)(mian)(mian)(mian)質(zhi)量的(de)(de)規定(ding)(ding)(ding)都比(bi)(bi)較籠統。比(bi)(bi)如(ru)，日(ri)本JIS標(biao)(biao)準一(yi)般只用“鋼(gang)(gang)材表面(mian)(mian)(mian)(mian)不(bu)得存在(zai)對(dui)使用有(you)害的(de)(de)缺陷(xian)”。美國(guo)ASTM標(biao)(biao)準一(yi)般只用“鋼(gang)(gang)材應(ying)有(you)與生(sheng)產和(he)檢驗(yan)操作(zuo)一(yi)致的(de)(de)均(jun)勻質(zhi)量，不(bu)應(ying)有(you)其性質(zhi)和(he)程度對(dui)成品部件(jian)的(de)(de)成形和(he)加工(gong)產生(sheng)有(you)害的(de)(de)缺陷(xian)‘’等(deng)條文作(zuo)原(yuan)則性規定(ding)(ding)(ding)。但由于(yu)國(guo)外(wai)重視鋼(gang)(gang)材的(de)(de)表面(mian)(mian)(mian)(mian)加工(gong)，企(qi)業內部都要(yao)根據用戶(hu)要(yao)求(qiu)(qiu)(qiu)制定(ding)(ding)(ding)適合各(ge)種要(yao)求(qiu)(qiu)(qiu)的(de)(de)表面(mian)(mian)(mian)(mian)質(zhi)量內控標(biao)(biao)準，所以生(sheng)產的(de)(de)鋼(gang)(gang)材實際(ji)(ji)表面(mian)(mian)(mian)(mian)質(zhi)量很好(hao)。而我國(guo)標(biao)(biao)準對(dui)鋼(gang)(gang)材表面(mian)(mian)(mian)(mian)不(bu)允許或允許存在(zai)的(de)(de)缺陷(xian)名稱、局部缺陷(xian)清除深(shen)度的(de)(de)要(yao)求(qiu)(qiu)(qiu)等(deng)都規定(ding)(ding)(ding)的(de)(de)詳細(xi)具體，但生(sheng)產鋼(gang)(gang)材的(de)(de)實際(ji)(ji)外(wai)觀和(he)表面(mian)(mian)(mian)(mian)質(zhi)量與國(guo)外(wai)相比(bi)(bi)，有(you)些還存在(zai)一(yi)些差距。
