STKM11A STKM14B tubi ferrei ad currus
Specification
STKM11A gradus chalybis est ad fistulas carbonis in structuras mechanicas adhibitas, ex norma JIS G3445 orta, et gradus Iaponicae est.STKM11A tibia ferrea gradus, materia aequivalens SPHC, σ B ≥ 290MPa;CARBONES FERRUM pro STKM structurarum mechanicarum;
Notam SPHC originaliter torris germanica erat et etiam in Iaponia adhibita est.Postea a mola chalybe domestico Baosteel introducta est, laminis ferreis volventibus (quae SPCC respondentibus respondentibus) caldariis volventibus, aequivalens laminis calidis 10 # et 15 # ferro in vexillum nationalis GB699 introductum (National Standard for High Quality. Carbon structuralis Steel), cum contentus carbonis ambitus circa 0,1% -0.15%
