ASTM A178 GrC Seamless Boiler Steel Tube For Heat Exchanger
ASTM A178 GrC seamless steel tube pipe for boiler exchanger for pressure equipment, used at higher temper
Description
ASTM A178 standard referes to electric-resistance-welded tubes with minimum-wall-thickness. Materials are carbon steel and carbon-manganese steel, ASTM A178 pipe and tube is to be used in boiler tubes, boiler flues, superheater flues and safe ends. Steel Grades A (low-carbon steel), C (medium-carbon steel), or D (carbon-manganese steel). Manufacturing processes must include heat treatment, welding after cooling. Crush test shall be performed if required by customer.

Grade 304L is more readily available in most product forms, and so is generally used in preference to 321 if the requirement is simply for resistance to intergranular corrosion after welding. However 304L has lower hot strength than 321 and so is not the best choice if the requirement is resistance to an operating environment over about 500°C.
