京滬高速鐵路貫串北京、天津、河北、山東、安徽、江蘇、上海7省市，連接環(huán)渤海和長江三角洲兩大經(jīng)濟(jì)區(qū)。四省三市國土面積占全國的6.5%，人口占全國的四分之一，continuance占全國的40%，是我國經(jīng)濟(jì)發(fā)展**活躍和相當(dāng)有潛力的地區(qū)，客貨運(yùn)輸需求旺盛。在這一通道修建一條高標(biāo)準(zhǔn)、大能力的現(xiàn)代化高速鐵路，意義重大。除了對直接相關(guān)的產(chǎn)業(yè)鏈具有拉動作用外，京滬高速鐵路建設(shè)還給環(huán)渤海和長三角地區(qū)經(jīng)濟(jì)發(fā)展帶來強(qiáng)烈的衍生效應(yīng)。負(fù)責(zé)南京大勝關(guān)長江大橋北引橋施工的中鐵十一局團(tuán)體項(xiàng)目經(jīng)理譚發(fā)剛算了一筆賬：他們管段施工線路長度約l9公里，合同投資為9.66億，在京滬高速鐵路建設(shè)標(biāo)段中，盡管中鐵十一局團(tuán)體投資額是**小的，就地取材的砂石、碎石用度就達(dá)到8000多萬元；消耗拉絲不銹鋼板，比的用鋼量還要多，累計(jì)支出近2.3億元；消耗水泥l(xiāng)5萬多噸，累計(jì)支出近5000萬元；繳納給當(dāng)?shù)?*的營業(yè)稅達(dá)2500萬元。直接吸納近3000多名農(nóng)民工參與施工建設(shè)。除此以外，還帶來了大量農(nóng)副產(chǎn)品、服務(wù)業(yè)等方面的需求。

style="text-indent:25px">304和321不銹鋼主要區(qū)別是304不含Ti，321含Ti，Ti可以防止不銹鋼敏化，通俗的講就是提高不銹鋼的高溫使用壽命，也就是說在高溫環(huán)境下，321不銹鋼板比304不銹鋼板更加適合。 304和321不銹鋼外觀及物理性能非常相似，唯有化學(xué)成份方面有稍許區(qū)別： ? ? 首先，是321不銹鋼要求含有微量的鈦（Ti）元素（按ASTM A182-2008標(biāo)準(zhǔn)規(guī)定其含Ti量應(yīng)不小于碳（C）含量的5倍，但不太于0.7%，另注，304和321的碳（C）含量都是0.08%），而304中不含鈦（Ti)。 ? ??其次，是對鎳（Ni）含量的要求稍許不同，304是8%至11%之間，而321是9%至12%之間。 ? ??其三，是對鉻（Cr）含量的要求銷許不同，304是18%至20%之間，而321是17%至19%之間。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇無錫321不銹鋼帶代理商,321不銹鋼帶"
