The embrittlement of heat affected zones (HAZs) resulting from the welding of a P-doped 2. 25Cr-1Mo steel was studied by the analysis of the fracture appearance transition temperatures (FATTs) of the HAZs simulated under a heat input of 45 kJ/cm with different peak temperatures. The FATTs of the HAZs both with and without tempering increased with the rise of the peak temperature. https://parisnaturalfoodes.shop/product-category/boldocynara/
