ASTM A517 / A517M Grade A

Chemical Properties

Carbon	Manganese	Phosphorus,max^A	Sulfur,max^A	Silicon	Nickel	Chromium	Molybdenum	Boron	Zirconium
0.13–0.23	0.74–1.20	0.025	0.025	0.34–0.86	-	0.46–0.84	0.15–0.31	0.0025 max	0.05–0.15^C

Note: A Applied to both heat and product analyses.

C Zirconium may be replaced by cerium. When cerium is added, the cerium/sulfur ratio should be approximately 1.5 to 1, based on heat analysis.
