《鋼鐵產(chǎn)品牌號表示方法》（GB221-79）中規(guī)定，采用漢語拼音字母、化學(xué)元素符號和阿拉伯?dāng)?shù)字相結(jié)合的方法表示。自貢鍍鋅鋼材供應(yīng)商鋼材具有不滲漏性，便于做成密閉結(jié)構(gòu)。</p><div style="width:100%;text-align: center;"><img style="max-width:

>0.6%)。按磷、硫含量可以把碳素鋼分為普通碳素鋼(含磷、硫較高)、好碳素鋼(含磷、硫較低)和高級好鋼(含磷、硫更低)。一般鋼材中含碳量越高則硬度越**度也越高，但塑性降低。這類鋼主要保證力學(xué)性能，故其牌號體現(xiàn)其力學(xué)性能，用Q+數(shù)字表示，其中“Q”為屈服點(diǎn)“屈”字的漢語拼音字首，數(shù)字表示屈服點(diǎn)數(shù)值，例如Q275表示屈服點(diǎn)為275 MPa。若牌號后面標(biāo)注字母A、B、C、D，則表示鋼材質(zhì)量等級不同，含S、P的量依次降低，鋼材質(zhì)量依次提高。</p><p style="text-indent:25px">鋼材精度等級是指某些金屬材料，標(biāo)準(zhǔn)中規(guī)定有幾種尺寸允許偏差，并且按尺寸允許偏差大小不同，分為若干等級，叫作精度等級。精度等級按允許偏差分為普通精度、較高精度、高級精度等。精度等級愈高，其允許的尺寸偏差就愈小。在訂貨時(shí)，應(yīng)注意將精度等級要求寫入合同等有關(guān)單據(jù)中，鋼材牌號是指金屬材料的牌號，是給每一種具體的金屬材料所取的名稱。鋼的牌號又叫鋼號。我國金屬材料的牌號，一般都能反應(yīng)出化學(xué)成分。牌號不僅表明金屬材料的具體品種，而且根據(jù)它還可以大致判斷其質(zhì)量。這樣，牌號就簡便地提供了具體金屬材料質(zhì)量的共同概念，從而為生產(chǎn)、使用和管理等工作帶來很大方便。鋼材是基本上不含合金元素的高碳鋼，含碳量在0.65%～1.35%范圍內(nèi)，其生產(chǎn)成本低。</p><div

style="text-indent:25px">鋼材由Q+數(shù)字+質(zhì)量等級符號+脫氧方法符號組成。它的鋼號冠以“Q”，表示鋼材的屈服點(diǎn)，后面的數(shù)字表示屈服點(diǎn)數(shù)值，單位是MPa例如Q235表示屈服點(diǎn)（σs）為235MPa的碳素結(jié)構(gòu)鋼。必要時(shí)鋼號后面可標(biāo)出表示質(zhì)量等級和脫氧方法的符號。質(zhì)量等級符號分別為A、B、C、D。脫氧方法符號：F表示沸騰鋼；b表示半安定鋼：Z表示安定鋼；TZ表示特殊安定鋼，安定鋼可不標(biāo)符號，即Z和TZ都可不標(biāo)。例如Q235-AF表示A級沸騰鋼。專門用途的碳素鋼，例如橋梁鋼、船用鋼等，基本上采用碳素結(jié)構(gòu)鋼的表示方法，但在鋼號后面附加表示用途的字母。鋼材的主要元素除鐵、碳外，還有硅、錳、硫、磷等。內(nèi)江異形鋼材加工配送</p><p

style="text-indent:25px">鋼材是用來制造滾珠、滾柱和軸承套圈的鋼。軸承在工作時(shí)承受著極大的壓力和摩擦力，所以要求軸承鋼有高而均勻的硬度和耐磨性，以及高的彈性極限。對軸承鋼的化學(xué)成分的均勻性、非金屬夾雜物的含量和分布、碳化物的分布等要求都十分嚴(yán)格。電器工業(yè)用硅鋼主要用來制造電器工業(yè)用硅鋼片。硅鋼片是電機(jī)和變壓器制造中用量很大的鋼材。按化學(xué)成分硅鋼可以分為低硅鋼和高硅鋼。低硅鋼含硅量wSi1.0%～2.5%，主要用來制造電機(jī)；高硅鋼含硅量wSi 3.0%～4.5%,一般用來制造變壓器。它們的含碳量wc≤0．06%～0.08%。自貢鍍鋅鋼材供應(yīng)商</p><p
