/dans /par

Introduction La section II partie A de l'ASME BPVC : Spécifications des matériaux ferreux est une section du code des chaudières et des récipients sous pression de l'ASME (BPVC) qui couvre les spécifications des matériaux ferreux (principalement le fer) utilisés dans la construction de chaudières, de récipients sous pression et d'autres équipements sous pression. Cette section aborde spécifiquement les exigences relatives aux matériaux en acier et en fer, y compris le carbone […]

Analyse des causes des fissures annulaires dans les tubes en acier sans soudure trempés SAE 4140

/dans /par

The reason for the ring-shaped crack at the pipe end of the SAE 4140 seamless steel pipe was studied by chemical composition exam, hardness test, metallographic observation, scanning electron microscope, and energy spectrum analysis. The results show that the ring-shaped crack of SAE 4140 seamless steel pipe is a quenching crack, generally occurring at the […]
