35CrMoV,合金結構鋼。統一數字代號:A31352 標準:GB/T 3077-1988
特性及適用范圍:淬透性和高溫強度都優于34CrMo鋼,采用水-油淬火熱處理,能提高沖擊值。 550℃時的蠕變強度和持久強度均超過34CrMo,但經 5000h時效后,力學性能急劇下降。用作工作溫度 500~520 ℃以下的轉子、葉輪、發電機環鍛件及其他高應力下工作的重要零件及齒輪等。
【應用舉例】
這種鋼經調質后使用,在重型或中型機械制造業中,用來制造在高應力下工作的重要零件,如長期在 500~520℃下工作的汽輪機葉輪、高級渦輪鼓風機和壓縮機的轉子、蓋盤、軸盤、效率不大的發電機軸以及強力發動機的零件等。
35CrMoV, alloy structural steel. Unified digital code: A31352 standard: 3077-1988 GB/T
Characteristics and applicable scope: quenching and high temperature strength are better than 34CrMo steel, using water - oil quenching heat treatment, can improve the impact value. The creep strength and the endurance strength of the 550 are more than 34CrMo, but the mechanical properties decrease sharply after 5000h aging. Used as the working temperature of 500 ~ 520 degrees below the rotor, impeller, generator and other parts of the ring forgings and other important parts and gear.
[application example]
This kind of steel is used, in heavy or medium mechanical manufacturing industry, for manufacturing the important parts, such as the high stress work, such as the 500 ~ 520 for turbine impeller, high turbine blower and compressor rotor, cover plate, shaft plate, the efficiency of the generator shaft and powerful engine parts, etc..
對比MyBCIC今年和去年6月份各分項數據來看,九大大宗商品中,鋼鐵、能源、有色、橡塑、建材、化工、農產品、紡織價格指數均有不同程度的下跌,僅造紙價格指數出現小幅的上漲。
其中,鋼鐵、能源、有色、化工、橡塑、建材和紡織價格指數均超過10%。
選取今年1-6月份MyBCIC平均值更是可見,與去年同期相比,九大大宗商品齊齊下挫,且多品種跌幅同樣高達兩位數。
Comparative mybcic this year and last year in June the breakdown of the data, the nine commodities, iron and steel, energy, non-ferrous metals, rubber, building materials, chemical industry, agricultural products, textile price index showed different degrees of fell, only a paper-making price index appears small rise.
Among them, iron and steel, nonferrous metals, energy, chemical, rubber, textile and building materials price index exceeded 10%.
Selected this year 1-6 months mybcic average values is visible, compared with the same period last year, nine commodities Qi Qi fell and multi species decline as high as double-digit.
