Product introduction ASME SA 519 Grade 440 Carbon Steel Seamless Pipes are Low Carbon Steel Pipes with 0.12-0.18 % carbon content with combination of 0.90-1.20 % manganese. These Pipes are also known as mild steel pipes and tubes. ASME SA 519 Grade 440 Pipes are low-cost Pipes easy to form and shape. These pipes are manufactured as per ASME Specification and commercially referred as cs pipes or ms pipes. Low Carbon Steel Pipes are not as hard as hig carbon steel pipes,Though carburizing can increase its surface hardness.
