简单高强板依靠其优秀的各种性能取得了航空航天领域的青睐，使得超高强度钢已应用于航空航天领域，具体是怎么发展的呢？下面由济钢代理商厂家的小编为大家简单介绍一下。
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.
超高强度板在室温条件下大于550MPa、抗拉强度大于140kgf/mm2，通常还要求具有良好的塑韧性、优异的疲劳性能、断裂韧性和抗应力腐蚀性能，是应用于制造承受较高应力结构件的合金钢类，大量应用于火箭发动机壳体、飞机起落架、防弹钢板等性能有特殊要求的领域。

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.
镉是大家熟知的一种致癌物，在最初的飞机制造和在飞机维修过程中都存在明显的环境污染风险。此外，为了避免氢脆，镀镉工艺要求随后进行氢还原退火操作。另外，还有更高的可硬化性能。对于一个给定的截面尺寸，适合的淬火条件并不那么严格，因此，在热处理过程中几乎没有变形。它有代表性的回火温度是470℃，接近这个温度时，这种不锈钢有优异的热阻性能。
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.
