1. What is ASTM A519 1035 Steel Pipe?
A: ASTM A519 is the American Standard for seamless mechanical steel pipe. 1035 refers to medium-carbon steel with a carbon content of approximately 0.35%. This steel pipe must meet chemical composition, mechanical property, and dimensional tolerance requirements and is commonly used in machining, hydraulic systems, and other applications.
2. What is the chemical composition of 1035 steel?
A (Key component range):
Carbon (C): 0.32%–0.38%
Manganese (Mn): 0.60%–0.90%
Phosphorus (P), Sulfur (S): ≤0.040% (each)
Silicon (Si): 0.15%–0.35%
3. What are the mechanical property requirements for 1035 steel pipe?
Answer (ASTM A519 specifications):
Tensile strength: ≥515 MPa
Yield strength: ≥400 MPa
Elongation: ≥10% (50mm gauge length)
Hardness: Approximately 137-179 HB (Brinell hardness)
4. What are the main applications?
Answer:
Machinery components (shafts, gear blanks)
Hydraulic cylinders, automotive transmission components
General structural pipes (requiring welding or cold working)
5. What is the difference between AISI 1035 and ASTM A519?
Answer: AISI 1035 is a material designation, while ASTM A519 is a steel pipe manufacturing standard. A519 1035 is subject to additional seamless pipe processing, dimensional tolerances, and non-destructive testing (such as eddy current or ultrasonic) requirements.
