| titleOfInvention | Yield strength 345MPa grade high ductility thick steel plates and its production method |
| abstract | The present invention relates to a kind of yield strength 345MPa grade high ductility thick steel plates and its production methods.The steel plate meter includes: C:0.05~0.07%；Si:0.25~0.35%；Mn:1.4~1.5%；P :≤0.015%；S :≤0.005%；Als:0.015~0.03%；Nb:0.03~0.04%；Ca:0.001~0.0015%；Remaining is iron and inevitable impurity；The steel plate thickness is 40mm~80mm.The steel plate crystal grain produced using this method is tiny, and plasticity, toughness are good, and -40 DEG C of Charpy-V impact powers are all in 180J or more, far beyond standard requirements.The process system of this method is loose, can on generous printed line steady production. |
