ASME SA178/SA178M
Carbon Steel SA 178 Boiler Tube is general carbon steel supplied in the normalized condition. This alloy is processed from tempered, normalized and annealing process. These boilers are epitomized by having modest strength and impact toughness. These boilers are used where high-temperature services are required. These boilers are formed with between the temperatures 900 – 1200 degree C. The saturated times should be kept lower that prevents scaling. Moreover, time and temperature should be controlled.
These boilers have very good machinability; this reduces its machining costs. This alloy is resistive to corrosion in mild conditions. Moreover, these are resistive to pitting, crevice and stress corrosion cracking. These offer the best performance in elevated temperatures.
