Productum notitia

Q420 Steel Introduction
Q420 chalybs est Sinica chalybs gradus ardui Alloy Altissimi Roboris Structural Chalybis, Fortitudo cede est 420 MPa, parametri sunt probati cum 16mm diametro ferrei vel laminae ferreae, et vis distrahens 520-680 Mpa est, materia densitatis 7.85 g/ /cm3. Secundum GB/T 1591-2008, Q420 habet 5 gradus qualitates: Q420A, Q420B, Q420C, Q420D et Q420E. Nam Q420 ferrum aequivalens, chemicae compositio et proprietatibus mechanicis, quaeso vide tabulas infra contentas.
Features et Usus
Q420 ferrum altum vires habet, praesertim in statu normalized vel normalizato plus temperato, magnis comprehensivis proprietatibus mechanicis, adhiberi potest in magnis navibus, pontibus, statio instrumenti potentiae, mediae et magnae pressionis boilers, vasorum pressionum altarum, machinis elevatis, machinis fodiendis ac aliae magnae partes structurae iunctae.
