A low carbon grade, 304L is available which can be welded without impairing it’s corrosion resistance. Maximum temperature: 900 ° C. Webb10 sep. 2024 · Low-grade heat (below 373 kelvin) is abundant and ubiquitous but is mostly wasted because present recovery technologies are not cost-effective. The liquid-state thermocell (LTC), an inexpensive and scalable thermoelectric device, may be commercially viable for harvesting low-grade heat energy if its Carnot-relative efficiency (η r ) reaches …
