ASTM A519 grade 4130 alloy steel pipe for mechanical use

Standard: ASTM A519

ASTM A519 grade 4130 alloy steel pipe is alloy steel with molybdenum and chromium and strengthening agents. The addition of molybdenum improves toughness of 4130 alloy steel pipe. And the addition of chromium improves strength and corrosion resistance of 4130 alloy steel pipe. For ASTM A519 grade 4130 alloy steel pipe, we mainly supply round shape seamless pipe within 325mm outside diameter.
