Kev Ntsuas Cov Txheej Txheem rau Hardness thiab Toughness ntawm NK Marine Steel Phaj Qib FH32 rau Nkoj

Hauv kev tsim cov nkoj, qhov zoo thiab cov khoom siv ntawm cov khoom siv, xws li NK Marine Steel Phaj Qib FH32, yog qhov tseem ceeb tshaj plaws. Lub hardness thiab toughness ntawm qib steel no muaj feem cuam tshuam rau cov qauv kev ncaj ncees thiab kev nyab xeeb ntawm cov nkoj. Yog li ntawd, txoj kev xeem kom raug thiab txhim khu kev qha yog qhov tseem ceeb los ntsuas cov khoom no.

Kev ntsuam xyuas hardness yog ib qho tseem ceeb ntawm kev ntsuam xyuas cov yam ntxwv ntawm NK Marine Steel Phaj Qib FH32. Ib txoj kev siv feem ntau yog Rockwell hardness test. Qhov kev ntsuam xyuas no ntsuas qhov tob ntawm kev nkag mus ntawm lub pob zeb tawv tawv lossis pob zeb diamond indenter nyob rau hauv ib qho kev thauj khoom tshwj xeeb. Rockwell scale muab tus nqi ntau uas qhia txog qhov hardness ntawm cov khoom. Cov nplai sib txawv, xws li Rockwell B (HRB) thiab Rockwell C (HRC), raug xaiv raws li qhov xav tau hardness ntau yam ntawm cov hlau.

Kev ntsuas toughness yog qhov tseem ceeb sib npaug los ntsuas lub peev xwm ntawm NK Marine Steel Phaj Qib FH32 kom nqus tau lub zog thiab tiv thaiv kev puas tsuaj. Charpy impact test yog ib txoj kev siv dav dav. Cov qauv ntawm tus qauv loj thiab cov duab yog npaj los ntawm steel phaj thiab raug rau ib qho kev cuam tshuam tam sim ntawd. Lub zog absorbed thaum lub sij hawm tawg yog ntsuas, thiab qhov no qhia txog cov khoom toughness.
