Products Description
Lork Group high-quality AISI 310 (1.4841/X15CrNiSi25-21/UNS S31000) is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. AISI 310 resists oxidation up to 2010oF (1100℃) under mildly cyclic conditions.
Because of its high chromium and moderate nickel content, 310 is resistant to sulfidation and can also be used in moderately carburizing atmospheres.
The more severe carburizing atmospheres of thermal press equipment usually require nickel alloys such as 330 (UNS N08330). 310 can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced. Alloy 310 also finds usage in cryogenic applications with low magnetic permeability and toughness down to -450oF (-268℃). When heated between 1202 – 1742oF (650 – 950℃) the alloy is subject to sigma phase precipitation. A solution annealing treatment at 2012 – 2102oF (1100 – 1150℃) will restore a degree of toughness.
