簡單高強(qiáng)板依靠其優(yōu)秀的各種性能取得了航空航天領(lǐng)域的青睞，使得超高強(qiáng)度鋼已應(yīng)用于航空航天領(lǐng)域，具體是怎么發(fā)展的呢？下面由濟(jì)鋼代理商廠家的小編為大家簡單介紹一下。
The simple high strength board has been favored by the aerospace field by its excellent properties, which makes ultra high strength steel already used in aviation and aerospace fields. How is it developed? The following by the Jinan Iron and steel agents small manufacturers for everyone to brief introduction.
超高強(qiáng)度板在室溫條件下大于550MPa、抗拉強(qiáng)度大于140kgf/mm2，通常還要求具有良好的塑韌性、優(yōu)異的疲勞性能、斷裂韌性和抗應(yīng)力腐蝕性能，是應(yīng)用于制造承受較高應(yīng)力結(jié)構(gòu)件的合金鋼類，大量應(yīng)用于火箭發(fā)動(dòng)機(jī)殼體、飛機(jī)起落架、防彈鋼板等性能有特殊要求的領(lǐng)域。

Ultra high strength plate at room temperature is greater than 550MPa, the tensile strength is more than 140kgf/mm2, usually is required ductility and toughness, excellent fatigue properties, fracture toughness and stress corrosion resistance good, is used in the manufacture of high alloy steel should force structure, widely used in the rocket engine shell, aircraft landing bulletproof steel frame, etc. the special requirements of the field.
鎘是大家熟知的一種致癌物，在最初的飛機(jī)制造和在飛機(jī)維修過程中都存在明顯的環(huán)境污染風(fēng)險(xiǎn)。此外，為了避免氫脆，鍍鎘工藝要求隨后進(jìn)行氫還原退火操作。另外，還有更高的可硬化性能。對于一個(gè)給定的截面尺寸，適合的淬火條件并不那么嚴(yán)格，因此，在熱處理過程中幾乎沒有變形。它有代表性的回火溫度是470℃，接近這個(gè)溫度時(shí)，這種不銹鋼有優(yōu)異的熱阻性能。
Cadmium is a well-known carcinogen, which has obvious risk of environmental pollution in the initial aircraft manufacture and aircraft maintenance. In addition, in order to avoid hydrogen embrittlement, the cadmium plating process requires subsequent reduction of hydrogen to annealing operations. In addition, there is a higher hardening performance. For a given section size, the suitable quenching condition is not so strict, therefore, there is almost no deformation in the heat treatment process. It has a typical tempering temperature of 470 degrees C, near this temperature, this stainless steel has excellent thermal resistance.
