Chemical composition of grade S420NL

 

Ladle analysis. 
S - sulphur content of 0,010 % max. can be agreed in the order for all products with a thickness of ≤ 16 mm intended for railway construction. 
The minimum value for the Al total content shall not apply if the steel contains sufficient quantities of nitrogen-fixing elements. 
CEV maximum carbon equivalent value CEV = C + Mn / 6 + (Cr + Mo + V) / 5 + (Cu + Ni) / 15
