Description
Grade :S420N
Number:1.8902
Classification:Alloy special structural steel
Standard:
EN 10025-3: 2004 Hot rolled products of structural steels. Technical delivery conditions for normalized/normalized rolled weldable fine grain structural steels
EN 10113-2: 1993 Hot-rolled products in weldable fine grain structural steels. Delivery conditions for normalized/normalized rolled steels


Chemical composition % of steel S420N (1.8902): EN 10025-3-2004
Nominal thickness =< 63(mm) CEV max = 0.48
Nominal thickness from 63 to 100 (mm) CEV max = 0.50
For long products the P and S content can be 0.005% higher
For railway application a maximum S content of 0.01% may be agreed at the time of enquiry and order
In sufficient other N-binding elements are present the minimum total Al content does not applay
Cu content above 0.4% may cause hot shortness during hot forming
