Description

35KH18N24S2L steel is used: for the manufacture of castings of parts operating at high temperatures in siliconarmenia condition (furnace conveyors, screws, fasteners); hinged cast chains for rotary kilns, consisting of heat-resistant and heat-resistant parts used in hot zone with the gas stream temperature to +900−1200 °C.

Note

Austenitic steel, corrosion resistant, heat resistant, heat resistant up to +1100−1200 °C.
