冷軋板，也稱作冷軋鋼板、冷軋薄板、冷板。包括不銹鋼板、彈簧鋼板、硅鋼片、鍍鋅板、鍍錫板、鍍鋁板等。冷軋板主要用于零件的沖壓加工，而冷軋板的力學(xué)性能十分重要，它直接關(guān)系到板材的沖壓性能。冷軋板是以不同的熱處理狀態(tài)分級(jí)的，不同硬度的材料，用于不同的加工方法。國(guó)家標(biāo)準(zhǔn)GB/T13237-1991《優(yōu)質(zhì)碳素結(jié)構(gòu)鋼冷軋薄鋼板和鋼帶》將冷軋薄板大致分為三級(jí)，P級(jí)用于普通沖壓，S級(jí)用于深度沖壓，Z級(jí)用于**深度沖壓。中國(guó)冶金標(biāo)準(zhǔn)YB/T5059-1993《低碳鋼冷軋鋼帶》將冷軋板帶按硬度分為五級(jí)，即：TR（特軟）、R（軟）、BR（半軟）、DY（低硬）和Y（冷硬）。其實(shí)通過一定的冷軋變形程度和冷軋后熱處理程度的適當(dāng)配合，可以在更***的范圍內(nèi)滿足用戶關(guān)于材料力學(xué)性能方面的要求。冷軋板根據(jù)用戶加工上的要求還可以分成更多的級(jí)別。例如：日本工業(yè)標(biāo)準(zhǔn)JISG3141-1996《冷軋?zhí)妓劁撲摪搴弯搸А返姆诸惓譃橐话阌茫╯pcc）、沖壓用(spcd)和深沖壓用（spce）三類外，還細(xì)分為退火、標(biāo)準(zhǔn)調(diào)質(zhì)、1/8硬、1/4硬、1/2硬、全硬等級(jí)別。在冷軋板力學(xué)性能的檢測(cè)方面，一些標(biāo)準(zhǔn)只規(guī)定了拉伸試驗(yàn)，另一些標(biāo)準(zhǔn)除拉伸試驗(yàn)外還規(guī)定了硬度試驗(yàn)。中國(guó)標(biāo)準(zhǔn)GB/T13237-1991就只規(guī)定了冷軋板的拉伸試驗(yàn)。邵氏硬度機(jī)邵氏硬度計(jì)本硬度計(jì)（橡膠硬度計(jì)）能快速測(cè)定塑料、橡膠、合成樹脂等的邵氏硬度。</p><div

將其壓入材料表面，通過觀察其表面凹坑的大小，來得到其主要參數(shù)(kgf/mm2)。雖然表達(dá)材料硬度的種類有多種，而且每種材料的檢測(cè)方式不同，但是其實(shí)各種硬度之間是可以進(jìn)行相互換算的，具體如下：洛氏硬度與維氏硬度的換算(1)洛氏硬度與維氏硬度的換算公式是通過對(duì)Hans·Qvarnstorm提出的TheQvarnstorm總結(jié)得到的：而且，此公式用我國(guó)公布的黑色金屬硬度標(biāo)準(zhǔn)數(shù)據(jù)進(jìn)行換算，其HRC誤差大約保持在±HRC范圍內(nèi)，而且就算差別很大也就士。(2)通過使用大小不一的力擠壓被測(cè)材料，然后通過對(duì)洛氏硬度與維氏硬度壓痕深度關(guān)系曲線的分析得出換算公式。本公式與國(guó)家標(biāo)準(zhǔn)實(shí)驗(yàn)換算值對(duì)照,通過這種方式得到的換算值之誤差竟只有±。洛氏硬度與布氏硬度的換算(1)對(duì)布氏壓痕和洛氏壓痕深度關(guān)系進(jìn)行分析，通過壓頭的應(yīng)力得出換算公式計(jì)算結(jié)果與國(guó)家標(biāo)準(zhǔn)實(shí)驗(yàn)值對(duì)照，且換算誤差為±。(2)根據(jù)實(shí)際實(shí)驗(yàn)數(shù)據(jù)用線性回歸法得到公式，且其公式誤差偏大，正常情況下，可以通過范圍偏小，不過，這種方法一般使用在精度要求不高的情況下可以使用。加載前要檢查加載手柄是否放在卸載位，加載時(shí)動(dòng)作要輕穩(wěn)，不要用力太猛。供應(yīng)硬度機(jī)對(duì)照表</p><p

比如食鹽、汗跡、海水、海風(fēng)、土壤等等。不銹鋼在氯離子存在下的環(huán)境中，腐蝕很快，甚至超過普通的低碳鋼。所以對(duì)不銹鋼的使用環(huán)境有要求，而且需要經(jīng)常擦拭，除去灰塵，保持清潔干燥。（這樣就可以給他定個(gè)“使用不當(dāng)”。）美國(guó)有一個(gè)例子：某企業(yè)用一橡木容器盛裝某含氯離子的溶液，該容器已使用近百余年，上個(gè)世紀(jì)九十年代計(jì)劃更換，因橡木材料不夠現(xiàn)代，采用不銹鋼更換后16天容器因腐蝕泄漏。2.沒有經(jīng)過固溶處理。合金元素沒有溶入基體，致使基體組織合金含量低，抗蝕性能差。3.這種不含鈦和鈮的材料有天生的晶間腐蝕的傾向。加入鈦和鈮，再配以穩(wěn)定處理，可以減少晶間腐蝕。從金相學(xué)角度分析，因?yàn)椴讳P鋼含有鉻而使表面形成很薄的鉻膜，這個(gè)膜隔離開與鋼內(nèi)侵入的氧氣起耐腐蝕的作用。為了保持不銹鋼所固有的耐腐蝕性，鋼必須含有12%以上的鉻。304是一種通用性的不銹鋼，它***地用于制作要求良好綜合性能（耐腐蝕和成型性）的設(shè)備和機(jī)件。304不銹鋼是按照美國(guó)ASTM標(biāo)準(zhǔn)生產(chǎn)出來的不銹鋼的一個(gè)牌號(hào)。304相當(dāng)于我國(guó)的0Cr19Ni9(0Cr18Ni9)不銹鋼。304含鉻19%，含鎳9%。定制硬度機(jī)備件</p><p>
