In other words, these are mainly quenched-and-tempered steels. When these steels are welded they are prone to softening in the heat-affected zone , . This region will therefore exhibit low hardness and therefore low strength and
Heat Treatment of Bolts & Fasteners - Purpose of Heat as3678 to 350 low alloy steel plate Heat treatment
Higher carbon steels can be hardened, while low carbon steels are considered non-hardenable. The steel in low-strength ASTM A307 or SAE Grade 2 fasteners is a low carbon grade, such as AISI 1018 or 1020. Grade 304 or 316 austenitic stainless steel fasteners contain little carbon and therefore cannot be hardened by heat treatment.Heat Treating of Aluminum Alloys - NIST200 precipitation heat ~ J treating I A,+ooA,2 I I i 200 ol I l t I 0 2 8 10 12 Copper, % Portion of aluminum-copper binary phase diagram.
