ASTM A519 seamless steel pipe is made of carbon steel and alloy steel, and are used for structural or other mechanical purposes involving machining or heat treatment, where close tolerances, smoothness or clear physical properties are important factors. ASTM A519 seamless steel pipe is a cost-effective alternative to DOM steel pipe.
ASTM A519 seamless steel pipe comply with the standard specifications for seamless carbon steel and alloy steel mechanical pipes, hot or cold worked. The ASTM A519 seamless steel pipe used in the mechanical tube can be cast into an ingot or a cast billet.
When continuous casting billets of different grades of ASTM A519 seamless steel pipe, the resulting transition materials need to be marked. The grades range from MT1010 to 4142, of which grade 1026 is carbon steel mechanical pipe.
