14nicr10是什么材料

14nicr10是什么材料？蘇州倍徠斯供應國產/進口14nicr10材料，14nicr10圓鋼，14nicr10圓棒

14nicr10是用途較廣的高級滲碳鋼，與15Cr、20Cr鋼相比，其強度、塑性、淬透性均高。淬火加低溫回火或高溫回火后，均具有良好的綜合力學性能，低溫沖擊韌性度好，缺口敏感性小，可加工性及焊接性尚好，但有回火脆性，白點敏感性較高，滲碳后均需進行二次淬火，特殊情況還需要冷處理。

14nicr10 is a widely used high carbon steel, compared with 15Cr, 20Cr steel, its strength, plasticity, and high - permeability. After quenching and low temperature tempering or high temperature tempering, has good comprehensive mechanical properties, good low temperature impact toughness, small notch sensitivity, machining and welding is good, but temper brittleness, white has a high sensitivity, after carburizing are required to secondary quenching, special circumstances need cold treatment.

主要用來制作重負荷條件下要求高強度，高硬度和高韌性的主軸及要求中心韌性很高或承受沖擊負荷、表面耐磨、熱處理變形小的軸、桿以及在高速和沖擊負荷下工作的各種傳動齒輪、調節螺釘、凸輪軸。

Mainly used in the production of high strength, high hardness and high toughness of the main shaft and the requirements of high strength or high impact load, surface wear, heat treatment deformation of the shaft, rod, and under the high speed and impact load of various drive gear, adjusting screw, cam shaft.

山東地區的庫存變化有一個較為明顯的特點，就是每年年底開始庫存會快速的增長，然后隨著氣候轉暖，特別是3、4月份開始庫存逐步開始下降。這是因為每年從11月底以后，山東地區的需求總量就開始因為天氣轉冷而大幅減少，直至冰點，而鋼廠方面實際檢修的時間并不多，因此就造成了庫存的堆積。待到來年開春，需求回暖之際，庫存才開始慢慢下降。而且由于鋼鐵行業的不景氣，貿易商大量流失，屯貨者也大幅減少，往年工地上堆滿鋼材的景象再也難得一見，工地多是按需取貨，拿貨量很少有超過3天以上的，中間商喪失"蓄水池"作用，同時各大貿易商由于連年收成不利，現多走鋼廠直發渠道，只賺取中間的小額差價，故近幾年關門的貿易商不在少數，而庫存的峰值也是呈現出一個逐年下降的現象。而也是由于連年行情不佳，現山東省內各大鋼廠廠內庫存也是呈現連年減少的狀況，截至2015年10月9日，山東省內9家主導建材鋼廠廠內庫存總量約22.12萬噸（螺紋16.61萬噸、盤螺/高線5.51萬噸）。

Shandong area inventory changes have a more obvious characteristics is at the end of the year began inventory will be rapid growth, then with the climate warming, especially 3, April began to inventory gradually began to decline. This is because each year from the end of 11, the total demand for the Shandong area began as the weather turns cold and a substantial reduction, until the freezing point, while the actual maintenance of steel mills is not much, so it caused the accumulation of inventory. Until next spring, when demand picks up, stocks began to slowly decline. And because of the iron and steel industry downturn, loss of a large number of trader, Tun goods were also significantly reduced, in previous years, the site of piled steel scene is rare, the site is on demand pick up, take the volume rarely have more than 3 days or more, loss of middlemen "reservoir effect, also the major traders as a result of a bad harvests in successive years, now go straight steel channels, only to earn the middle of a small spread, so in recent years, closed the trader not in a few, and the peak value of the inventory is also showing a a declining phenomenon. And is due to poor market year after year, now Shandong Province of the large steel factory inventories is also present decreasing every year, as of October 9, 2015, Shandong Province nine leading building materials steel plant total inventory about 22.12 million tons (thread 16.61 million tons, valvata / wire 5.51 million tons).

萊蕪市場的價格與北京、上海、廣州主導市場對比來看，一直是低于廣州市場的價格，通常情況下與北京和上海的市場價格走勢相似性較大，這是由生產成本決定的。鋼材生產過程中鐵礦石所需比例最多，沿海城市可以更多地利用廉價的外礦資源。而今年以來，山東鋼廠檢修較去年無明顯變化，而今年7、8月間山東價格明顯觸底并出現一定反彈，這是由于轄區內所有鋼廠步調較為一致，往往通過集中開會的方式，集體保證價格正常運行。另外值得注意的是隨著今年"金九銀十"的落空，山東建材價格也隨著外圍主導市場逐步走弱，但二線資源的三級大螺紋每每跌倒1870元/噸一線時，鋼廠總能集體站出來實行挺價措施，可見在生產成本較高的現階段，1870元/噸是山東各大鋼廠的生命線，過度的生產虧損是鋼廠所不愿看到的情景。但長期壓榨其代理商利潤也不是長久之計，雖然目前省內資源庫存量偏低，但依舊建議貿易商注意倉儲量，謹慎防范不必要的風險。

Laiwu market prices and Beijing, Shanghai, Guangzhou leading market comparison, has been lower than the price of the Guangzhou market, usually with the Beijing and Shanghai market price trend is relatively large, which is determined by the production costs. Iron ore in the process of production of iron ore is the largest proportion, coastal cities can more use of cheap foreign mineral resources. And this year, Shandong steel mills overhaul, and this year 7, August Shandong prices bottomed out and a certain rebound, which is due to the area within the pace of all the more consistent, often through the focus of the way to ensure the normal operation of the price. Also worth noting is with this year "the golden nine silvers ten" frustrated, Shandong building materials prices also with the periphery of the dominant market is gradually weakening, but second tier resource of three large thread often fall of 1870 yuan / ton line, steel always collective stand out to implement very price measures, visible in the current stage of the production cost is high, 1870 yuan / ton is the lifeline of Shandong major steel mills, excessive production loss is the steel mills do not want to see the scene. But in the long run, squeezing the profit agencies is not a permanent solution, although the province resource inventory is low, but still recommend trader attention to the warehouse storage, careful to prevent unnecessary risk.
