By subjecting the metal to controlled heating and cooling cycles, PWHT aims to relieve residual stresses, temper the material, and remove hydrogen, thereby improving dimensional stability and reducing susceptibility to stress corrosion and brittle fracture. At TechCorr's Thermal Division, we prioritize adherence to industry codes and standards, ensuring that PWHT processes are executed meticulously to preserve the integrity and longevity of critical equipment.

Our expert team evaluates material composition, thickness, and prior thermal history to determine the appropriate PWHT parameters, safeguarding against reduced tensile strength, creep resistance, and notch toughness. Consult with TechCorr's Thermal Division experts to determine the necessity and optimal approach for PWHT, recognizing that not all materials require this treatment and that incorrect execution can lead to detrimental effects on component performance and durability.
