3103 Chemical Element Composition Content (%)

Component	Fe	Si	Mn	Cr	Cu	Zn	Mg	Other Individual	Other Total	More
Minimum Value	-	-	0.9	-	-	-	-	-	-	Al:余量；Zr+Ti≤0.1
Maximum Value	0.7	0.5	1.5	0.1	0.1	0.2	0.3	0.05	0.15	Al:余量；Zr+Ti≤0.1

"Other individual elements or other totals": The chemical composition includes elements not specified in the table. Analysis should only be conducted if these elements are suspected to be present, or if routine analysis suggests that their content may exceed the prescribed limits.
