Effect of Solution Heat Treatment on Properties of 2205 Duplex Stainless Steel Welded Joints
This paper introduces the chemical composition and mechanical properties of 2205 duplex stainless steel,and analyzes the role of its alloy composition.40mm thickness of SA-240 S32205 duplex stainless steel plate was used in the test,and GTAW+SAW welding method was used for welding.After welding,the test plate was cut into two parts,and the one half was 1060 ℃ × 90 min solution heat treatment.After solution heat treatment,tensile,bending,impact,hardness,ferrite,pitting test and microstructure test were carried out on the two test plates.The test results show that after solution heat treatment,the welding joint and weld metal tensile strength,weld ferrite,weld and heat affected zone hardness decreased,and the impact property and pitting resistance were improved.
