|---|---|
| Standard Name / Number | ASTM A287 – Specification for Rolled Carbon-Steel Locomotive Frames |
| Status | Withdrawn / Inactive (no longer an active ASTM standard) |
| Application | Originally intended for locomotive frames and related heavy structural parts |
| Availability | The official document exists but is not publicly accessible; technical details such as chemical composition and mechanical properties are not widely available. |
The ASTM A287 specification has been withdrawn, meaning it is no longer maintained or updated by ASTM.
It was likely used historically for structural carbon steel plates and shapes designed to handle large mechanical loads and fatigue stresses — especially in locomotive construction.
Because it’s obsolete, it’s rarely found in modern materials databases.
When you see “Carbon Steel A287” mentioned today, it’s often:
From older documentation or legacy equipment, or
A mislabeling or confusion with similar designations such as A285, A387, or A516, which are still active standards for carbon or pressure vessel steels.
If you’re looking for a similar or replacement material for modern use, consider one of these standards:
| Modern ASTM Grade | Type / Typical Use |
|---|---|
| ASTM A36 | General structural carbon steel (commonly used in frames and supports) |
| ASTM A285 | Pressure vessel carbon steel with moderate strength |
| ASTM A516 | Pressure vessel steel with improved notch toughness |
| ASTM A387 | Alloy steel (chromium-molybdenum) for high-temperature service |
