What is the chemical specification for corten A and corten B steel

Posted:2020-11-09 15:13:39

The corten A and corten B steel are hot rolled structural steels. The chemical specification for corten A and corten B steel makes the materials obtain improved atmospheric corrosion resistance. Then what is the chemical specification for corten A and corten B steel?

Chemical specification for corten A and corten B steel:

Grade	C	Si	Mn	P	S	Al	V	Cu	Cr	Ni
Corten A	0.12	0.25/0.75	0.20/0.50	0.07/0.15	0.030	0.015/0.06	–	0.25/0.55	0.50/1.25	0.65
Corten B	0.19	0.30/0.65	0.80/1.25	0.035	0.030	0.020/0.06	0.02/0.10	0.25/0.40	0.40/0.65	0.40

The chemical specification for corten A and corten B steel enables the materials to be used for bridges, trains, cars, trucks and industrial facilities and so on applications. The top layer of corten A and corten B steel reacts with atmospheric elements to form a rust coloured protective layer, which not only makes corten A and corten B steel virtually maintenance free but also provides a pleasing and consistent finish.
