style="text-indent:25px">鋼材應(yīng)用普遍、品種繁多，根據(jù)斷面形狀的不同，鋼材一般分為型材、板材、管材和金屬制品四大類。鋼材是鋼錠、鋼坯或鋼材通過壓力加工制成的一定形狀、尺寸和性能的材料。大部分鋼材加工都是通過壓力加工，使被加工的鋼（坯、錠等）產(chǎn)生塑性變形。根據(jù)鋼材加工溫度不同，可以分為冷加工和熱加工兩種。鋼材是鋼錠、鋼坯或鋼材通過壓力加工制成所需要的各種形狀、尺寸和性能的材料。黑色金屬主要指鐵、錳、鉻及其合金。把煉鋼用生鐵放到煉鋼爐內(nèi)按一定工藝熔煉，即得到鋼。黑色金屬以外的金屬稱為有色金屬，如銅、錫、鉛、鋅、鋁以及黃銅、青銅、鋁合金和軸承合金等。</p><p style="text-indent:25px">鋼材服務(wù)中心這是一種比較重要的銷售方式。服務(wù)中心從各個(gè)鋼廠大筆買進(jìn)鋼材（買斷式）放在自己的倉庫，在倉庫小批量銷售，滿足客戶的各種采購需求。為方便用戶，有50%的鋼材通過加工剪切后再銷售給用戶。這種貿(mào)易商的作用是：在鋼廠大量定貨，使鋼廠可按訂單滿負(fù)荷生產(chǎn)；及時(shí)付款，鋼廠不承擔(dān)資金風(fēng)險(xiǎn)；整合鋼廠資源，滿足客戶的建立銷售網(wǎng)絡(luò)。介紹新產(chǎn)品。其要求是：一定要有倉儲(chǔ)場地、倉儲(chǔ)設(shè)備和加工設(shè)備；而要有一定的資金實(shí)力；三要有普遍的營銷渠道；四要有良好的信譽(yù)和服務(wù)手段。這種形式的銷售量約占全部銷售量的30%。鋼材在熱軋或鍛造后不再對其進(jìn)行專門熱處理，冷卻后直接交貨。</p><div

style="text-indent:25px">鋼材狀態(tài) 經(jīng)冷拉、冷軋等冷加工成型的鋼材，不經(jīng)任何熱處理而直接交貨的狀態(tài)，稱為冷拉或冷軋狀態(tài)。與熱軋(鍛)狀態(tài)相比，冷拉(軋)狀態(tài)的鋼材尺寸精度高、表面質(zhì)量好、表面粗糙度低，并有較高的力學(xué)性能,由于冷拉(軋)狀態(tài)交貨的鋼材表面沒有氧化皮覆蓋，并且存在很大的內(nèi)應(yīng)力，極易遭受腐蝕或生銹，因而冷拉(軋)狀態(tài)的鋼材，其包裝、儲(chǔ)運(yùn)均有較嚴(yán)格的要求，一般均需在庫房內(nèi)保管，并應(yīng)注意庫房內(nèi)的溫濕度控制。鋼材出廠前經(jīng)退火熱處理，這種交貨狀態(tài)稱為退火狀態(tài)。退火的目的主要是為了和改善前道工序遺留的組織缺陷和內(nèi)應(yīng)力，并為后道工序作好組織和性能上的準(zhǔn)備,合金結(jié)構(gòu)鋼、保證淬透性結(jié)構(gòu)鋼、冷鐓鋼、軸承鋼、工具鋼、汽輪機(jī)葉片用鋼、鐵索體型不銹耐熱鋼的鋼材常用退火狀態(tài)交貨。鋼材是在鋼中加入一些使鋼變脆的元素，從而有利于提高切削速度和延長刀具壽命。自貢工業(yè)鋼材</p><p style="text-indent:25px">鋼材能防腐和防白蟻侵害，并能自動(dòng)修復(fù)涂層的破損。自貢工業(yè)鋼材</p><p style="text-indent:25px">鋼中有益元素有錳、硅、釩、鈦等，控制摻入量可冶煉成低合金鋼。鋼中主要的有害元素有硫、磷及氧，要特別注意控制其含量。磷是鋼中很有害的元素之一，主要溶于鐵素體起強(qiáng)化作用。磷含量增加，鋼材的強(qiáng)度、硬度提高，塑性和韌性卓著下降。特別是溫度愈低，對塑性和韌性的影響愈大，從而卓著加大鋼材的冷脆性。磷也使鋼材可焊性卓著降低，但磷可提高鋼的耐磨性和耐蝕性。硫也是很有害的元素，呈非金屬硫化物夾雜物存在于鋼中，降低鋼材的各種機(jī)械性能。由于硫化物熔點(diǎn)低，使鋼材在熱加工過程中造成晶粒的分離，引起鋼材斷裂，形成熱脆現(xiàn)象稱為熱脆性。硫使鋼的可焊性、沖擊韌性、耐疲勞性和抗腐蝕性等均降低。氧是鋼中有害元素，主要存在于非金屬夾雜物中，少量熔于鐵素體內(nèi)。非金屬夾雜物降低鋼的機(jī)械性能，特別是韌性。氧有促進(jìn)時(shí)效傾向的作用。氧化物所造成的低熔點(diǎn)亦使鋼的可焊性變差。自貢工業(yè)鋼材</p><p
