Quick Answers
AISI 1020 ERW Pipes – Overview
AISI 1020 is a low-carbon, general-purpose steel that offers excellent weldability, machinability and formability. Its low carbon content (0.18–0.23%) makes it ideal for cold-drawn shafts, pins, fasteners and lightly stressed structural parts.
BB Infras stocks AISI 1020 ERW Pipes in rounds, hexagonals and profiles from leading Indian and European mills, regularly supplied to gear manufacturers, machine builders and automotive component suppliers with hardness and impact test reports on request. We supply AISI 1020 ERW Pipes in schedules SCH 10 through XXS, in lengths from 3 m single random to 6 m double random, with plain end, bevel end or threaded end as required. PE/BE/TE pipes are stocked for same-day dispatch.

| 2 | Tensile & Yield Strength | ASTM E8 | ≥380 MPa / ≥210 MPa |
| 3 | Elongation | ASTM E8 | ≥25% |
| 4 | Hardness (HB) | ASTM E10 | Per standard max |
| 5 | Hydrostatic Test | AISI / ASME B31.3 | Leak-free at test pressure |
| 6 | Dimensional Inspection | ASME B36.10M | Within tolerance |
| 7 | Visual & Surface | ASTM A530 / MSS SP-55 | Free from defects |
| 8 | Ultrasonic Testing (UT) | ASTM E213 (on request) | No sub-surface defects |
| 9 | PMI (XRF) | ASTM E1476 (on request) | Grade confirmation |
Storage & Handling Guidelines
- Store on wooden dunnage or pipe racks — never directly on concrete to avoid moisture-induced corrosion.
- Stack with appropriate separators; observe safe stack heights to prevent deformation.
- Apply plastic end caps or plugs to all open ends to prevent ingress of moisture, dust and insects.
- Keep material dry and ventilated; store under cover in humid or coastal climates.
- Use nylon slings or padded lifting hooks — never bare wire rope directly on surface.
- For long-term storage (>6 months), re-apply protective oil coating or wrap with VCI (Vapour Corrosion Inhibitor) film.
- Identify items with heat number tags throughout storage for full MTC traceability.
