  材料特性 Material Characteristics

  800合金从高温快冷后均处于奥氏体单项区,因此,使用状态为单一奥氏体组织。

  合金具有较高的铬含量和足够的镍含量,所以有较高的耐高温腐蚀性能,在工业中应用较多。

  在氯化物、低浓度的NaOH水溶液中和高温高压水中,具有优良的耐应力腐蚀破裂性能,所以用于制造耐应力腐蚀破裂的设备。

  1、加工硬化率大于奥氏体不锈钢,因此需要对加工设备进行挑选。冷加工材料应为固溶热处理态,并且在冷加工量较大时应进行中间退火。

  2、若冷加工量大于10%,则需要对工件进行二次固溶处理。

  The 800 alloy is in a single austenite region after rapid cooling from high temperature. Therefore, the use state is a single austenite structure.

  The alloy has a high chromium content and a sufficient nickel content, so it has high high temperature corrosion resistance, and is widely used in industry.

  It has excellent stress corrosion cracking resistance in chloride, low concentration NaOH aqueous solution and high temperature and high pressure water, so it is used to make equipment resistant to stress corrosion cracking.

  1. The work hardening rate is greater than austenitic stainless steel, so the processing equipment needs to be selected. Cold-worked materials should be in the solution heat-treated state, and intermediate annealing should be performed when the amount of cold-worked is large.

  2. If the cold working volume is greater than 10%, a second solution treatment is required for the workpiece.
