Chemical composition of grade S420N

	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
