How to select a Stainless Steel Reactor based on the experimental temperature?

When selecting a Stainless Steel Reactor for an experimental campaign, temperature is the first critical filter. Begin by mapping the entire thermal window your chemistry will experience: not only the set-point, but also exotherms, quench ramps and cleaning cycles. A Stainless Steel Reactor built from 316L is normally adequate for –20 °C to 250 °C; its chromium–nickel–molybdenum network resists mild chlorides and maintains toughness at cryogenic start-ups.  

If hydrogenation or carbonylation requires continuous operation above 300 °C, upgrade to a 316Ti or 310S Stainless Steel Reactor. The titanium-stabilised grade prevents carbide precipitation along weld seams, while 310S offers 19 % chromium and 25 % nickel to resist oxidative spalling at 600 °C. Should the route involve molten salts or fluorinated intermediates, a duplex 2205 Stainless Steel Reactor gives twice the yield strength of 316L and retards chloride-induced pitting when cycling between 150 °C and 400 °C.  

Always cross-check the pressure–temperature envelope supplied by the manufacturer: a 1-litre lab Stainless Steel Reactor rated 350 °C at 200 bar may lose 25 % of that rating . Finally, remember that repeated thermal shocks—from ice-bath removal to 250 °C oil heating—can nucleate micro-cracks; specify a forged flange and a tapered wall thickness gradient so your Stainless Steel Reactor survives at least 5000 cycles without leak.
