ASTM A 519 covers various grades of carbon and alloy steel seamless pipe. Grade 4130 is a versatile alloy with good resistance to atmospheric corrosion and reasonable strength up to around 315º c (600º f). It has high fatigue strength, wear and impact resistance, toughness and torsional strength. The following will talk about ASTM A519 4130 alloy steel pipe.
