E335 E355 Cov Qauv Hlau H Beam
E335 H seem nqaj yog cov hlau tsis tshua muaj hlau nrog cov khoom siv zoo heev. Cov hlau tsis tshua muaj hlau yog ib hom hlau uas ib qho me me ntawm cov hlau alloying ntxiv los txhim kho cov khoom ntawm cov hlau.E335 steel muaj qee qhov feem ntawm molybdenum thiab chromium cov ntsiab lus ntxiv los txhim kho nws lub zog thiab hardness.Qhov tensile lub zog ntawm E335 H seem yog 580-780MPa, uas yog cov hlau muaj zog. Lub caij no, nws lub zog tawm los yog 335MPa, uas yog vim li cas nws thiaj li hu ua E335.
E355 H hlau nqaj yog ib qho kev sib xyaw ua ke ntawm cov hlau uas muaj lub cev zoo thiab kev ua haujlwm. Nws yog tsim los ntawm carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P) thiab chromium (Cr), thiab lwm yam. E355 muaj ib tug siab modulus elasticity ntawm txog 2.1 × 10 ^ 5 MPa, uas muab nws zoo bending kuj thiab rigidity. Thib ob, cov hlau muaj lub zog tensile ntawm txog 630 MPa, uas muab nws cov khoom tensile zoo thiab ua rau nws tsim nyog siv los ua cov khoom ntawm kev xaiv rau cov khoom tseem ceeb.
