Manaʻoga Faʻapitoa
O le meafaitino o le tisiketi taofi e faʻaaogaina le tulaga faʻatonuina o le uʻamea efuefu 250 a loʻu atunuu, e taʻua o le HT250, lea e tutusa ma le tulaga faʻatonuina a Amerika G3000. O manaʻoga mo elemene autu e tolu o le tuufaatasiga vailaʻau o: C: 3.1∽3.4 Si: 1.9∽2.3 Mn: 0.6∽0.9. Manaʻoga faʻatino faʻainisinia: malosi o le tensile>=206MPa, malosi o le punou>=1000MPa, deflection>=5.1mm, manaʻoga o le maʻaʻa i le va o: 187∽241HBS.
