| Abstract: | Cr5Mo alloy steel contained some of Cr/Mo basic elements,pearlite microstructure,with excellent high-temperature sulfur corrosion,oxidation resistance and high temperature strength,but poor Cr5Mo steel welding.The tendency to crack Cr5Mo cold steel and then hot cracking susceptibility and the reasons for defects were analyzed,and technology and construction-related precautions were proposed. |
