1026 pipe is a seamless steel pipe that belongs to a material grade in the ASTM A519 standard, also known as 1026 seamless steel pipe.
It has the characteristics of high precision, high strength and good toughness, so it is widely used in mechanical structures, hydraulic systems, automobile manufacturing and other fields. The chemical composition of 1026 seamless steel pipe mainly includes elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P) and sulfur (S).
Size: 6mm-323.8mm.
Shape: Round or Special sections.
Length: Single random length/ Double random length or as customer's actual request.
Grade: SAE 1026 / AISI 1026 / GRADE 1026.
