Special AlloysSheet/Plate
Description (English)
HASTELLOY Alloy C-4 is supplied in the sheet solution heat-treated condition, delivering yield strength of 414 MPa, tensile strength of 765 MPa, elongation of 52%, and hardness of HRB 90. The alloy is manufactured to multiple ASTM standards covering plate/sheet/strip (B 575), rod (B 574), pipe and tube (B 619, B 622, B 626), and fittings (B 366). The titanium stabilization minimizes the formation of grain boundary carbides during thermal cycling, ensuring that corrosion resistance is maintained in welded and high-temperature-exposed conditions. HASTELLOY C-4 is widely used in the chemical process industry for heat exchangers, reactors, columns, and piping systems handling aggressive chemicals.
