Fermonic® 50 – HS/EHS是一种氮强化奥氏体不锈钢,在冷加工或温加工后供应。 虽然能够通过对直径非常小(<2.25英寸)的Fermonic® 50棒材进行冷加工来获得更高的强度,但只有通过在高温下变形,较大的截面尺寸才能在机械属性上得以显著增强。 这样可以产生一种变形和局部再结晶的“无应力”微观结构,让整个棒材获得高强度及良好的延性和稳定一致的属性(与冷加工后的材料不同)。 要获得出色的属性,Fermonic® 50 HS/EHS棒材的直径不能超过9英寸。
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。
