Seamless steel pipe information: What is the difference between American standard ASTM1010 seamless steel pipe and domestic 10 # steel
ASTM 1010 seamless steel pipe: commonly used for export projects in Europe and America, as well as for foreign oil and gas fluid transportation pipelines. It is compatible with the material inspection system of American standard projects and has a wider range of adaptability for cold stamping forming.
Domestic 10 # seamless steel pipe: widely used in domestic mechanical parts, ordinary fluid transportation, automotive deep drawing parts and other scenarios, with lower procurement costs, more complete domestic supply chain matching, and fully compliant with national standards for acceptance.
If used for domestic projects, directly selecting 10 # steel can meet the requirements; If implementing the American standard project, it is necessary to strictly verify the material book of ASTM 1010, confirm that the composition and performance meet the specified ASTM standard terms of the project, and not directly mix domestic 10 # steel without alternative procedures.
ASTM 1010 Seamless Steel Pipe: The core implementation of ASTM A29/A29M series standards requires steel pipe products to additionally comply with ASTM A519 and other specialized specifications for seamless steel pipes. It belongs to the American carbon steel grade system and is suitable for material access requirements of European and American industrial projects.
Domestic 10 # steel: Plate/bar shall comply with GB/T 699-2015 "High quality Carbon Structural Steel", seamless steel pipe shall comply with GB/T 8163-2018 "Seamless Steel Pipe for Fluid Transport", fully compatible with the national standard project acceptance system for domestic infrastructure and mechanical manufacturing.
ASTM 1010 (typical values for annealed state): yield strength of 172-315MPa, tensile strength of 310-430MPa, elongation of 29% -45%, wider performance range, and greater fluctuation range in different supply states.
Domestic 10 # steel (GB/T 8163): yield strength ≥ 205MPa, tensile strength 335-475MPa, elongation at break ≥ 24%, clearer lower limit of indicators, and higher stability of material properties in the same batch.
The American standard ASTM 1010 seamless steel pipe and domestic 10 # steel are highly similar in basic properties and belong to low-carbon high-quality carbon structural steel that is approximately equivalent to international grades. However, there are clear differences in standard systems, composition tolerances, performance details, and applicable scenarios.
