Fermonic® 50 – Annealed是一种氮强化奥氏体不锈钢,在退火后供应。 它的屈服强度几乎是Alloy 304和Alloy 316L等普通奥氏体不锈钢的两倍,具有减小截面尺寸的潜力,从而降低重量和成本。 可通过冷加工获得更高的强度。 重要的是,它仍然是全奥氏体,即使是在剧烈的冷加工后,也完全没有磁性。
这种合金在高温和低温下都具有出色的延性和韧性,并且较其他奥氏体不锈钢种具有更高的耐磨蚀和耐侵蚀性,从而成为了一种适用于各种严苛应用的实用且具成本效益的合金。 它通常能够以与其他3xx合金相同的方式进行成形和焊接,但由于其较高的加工硬化率,因此加工时可能需要放慢速度/消耗更多电力。 它在各类应用中具有与Alloy 317L同等或更好的耐腐蚀性,而得益于耐硫化物应力开裂的能力,它被NACE MR 01 75列为适用于酸性环境的材料。
