國內外不銹鋼標準都規定了鋼材熱處理后的室溫力學性能。由于化學成分、熱處理制度、取樣方法和試驗方法等存在差異，所以各標準規定的力學性能指標也是有差異的。但是在化學成分和試樣處理基本相同的情況下，性能指標還是大體相同的。

 從各標(biao)(biao)準(zhun)看(kan)，我(wo)國標(biao)(biao)準(zhun)和日(ri)本標(biao)(biao)準(zhun)規(gui)定(ding)(ding)的(de)(de)(de)力(li)學性(xing)能(neng)是鋼(gang)(gang)材本體或試樣毛坯(pi)熱(re)處理后(hou)的(de)(de)(de)性(xing)能(neng)。實際(ji)上(shang)(shang)我(wo)國的(de)(de)(de)不銹(xiu)鋼(gang)(gang)棒(bang)材一般是用試樣毛坯(pi)熱(re)處理后(hou)測定(ding)(ding)性(xing)能(neng)。而ISO、EN和DIN、BS等標(biao)(biao)準(zhun)以及ASTM大部分標(biao)(biao)準(zhun)，規(gui)定(ding)(ding)的(de)(de)(de)是鋼(gang)(gang)材熱(re)處理本體的(de)(de)(de)性(xing)能(neng)，鋼(gang)(gang)材熱(re)處理后(hou)直(zhi)接在材上(shang)(shang)取(qu)樣進行(xing)檢(jian)驗，只(zhi)有沉淀硬化(hua)鋼(gang)(gang)的(de)(de)(de)時效性(xing)能(neng)和馬氏體鋼(gang)(gang)的(de)(de)(de)淬火回火性(xing)能(neng)是用試驗毛坯(pi)熱(re)處理后(hou)進行(xing)檢(jian)驗。另外，EN標(biao)(biao)準(zhun)還(huan)規(gui)定(ding)(ding)了各類(lei)鋼(gang)(gang)在高溫（100~550℃)下的(de)(de)(de)Rp0.2的(de)(de)(de)值(zhi)。

 關于硬(ying)(ying)(ying)度試(shi)驗(yan)，ISO、EN、DIN等(deng)標(biao)(biao)(biao)準(zhun)(zhun)規(gui)定(ding)除奧氏(shi)體鋼(gang)外(wai)，一般都做(zuo)硬(ying)(ying)(ying)度試(shi)驗(yan)，ASTM、JIS和我國(guo)標(biao)(biao)(biao)準(zhun)(zhun)都規(gui)定(ding)有硬(ying)(ying)(ying)度試(shi)驗(yan)，其中JIS標(biao)(biao)(biao)準(zhun)(zhun)規(gui)定(ding)測定(ding)指標(biao)(biao)(biao)最多，包(bao)括HB、HV、HRB等(deng)，我國(guo)標(biao)(biao)(biao)準(zhun)(zhun)也采(cai)用了JIS標(biao)(biao)(biao)準(zhun)(zhun)的規(gui)定(ding)。

 ASTM鋼板（帶）標準(zhun)，各標準(zhun)不同，對奧氏(shi)體或(huo)鐵素(su)(su)體、馬氏(shi)體等各鋼類板、帶規定了(le)冷彎試(shi)驗(yan)(yan)，JIS和我國標準(zhun)對馬氏(shi)體和鐵素(su)(su)體鋼板（帶）規定了(le)冷彎試(shi)驗(yan)(yan)。
