At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM A29. ASTM A29/A29M is a general-requirements (umbrella) specification covering hot-wrought carbon and alloy steel bars – rounds, squares, hexagons, flats, and rectangles – in both hot-rolled and cold-finished condition. It defines manufacturing, tolerances, testing, and quality requirements common to many grade-specific bar standards; mechanical properties are set by the individual grade ordered, not by A29 itself.

| Grade / Class | UNS / Designation | Type / Notes |
|---|---|---|
| Carbon steel bars | 10xx / 11xx / 15xx series | Non-resulfurized, resulfurized, and rephosphorized carbon steels |
| Alloy steel bars | 41xx / 43xx / 51xx / 86xx series | Cr, Cr-Mo, Ni-Cr-Mo alloy steels |
Minimum mechanical requirements per ASTM A29.
| Grade / Class / Condition | Tensile Strength, min | Yield Strength, min | Elongation, min % | Hardness |
|---|---|---|---|---|
| Per ordered grade | Set by grade-specific standard / heat treatment | Set by grade | Set by grade | Set by grade |
| Grade | Key Composition, % |
|---|---|
| Carbon grades | Compositions per SAE J403 (e.g., 1045: C 0.43-0.50, Mn 0.60-0.90) |
| Alloy grades | Compositions per SAE J404 (e.g., 4140: C 0.38-0.43, Cr 0.80-1.10, Mo 0.15-0.25) |
Works with product-specific standards such as ASTM A108 (cold-finished bars), A311, A519, and grade chemistries in SAE J403/J404. International analogue for general bar requirements includes EN 10025 / EN 10083 grade families.
