| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
AnnealedDefault full/spheroidize annealed, softest supply condition | Pick for machining, cold forming or coiling before hardening; lowest hardness and best tool life. | 450 | 770 | 20 | 220 HB | — |
as-rolled bar/flat, untreated | Mill supply condition for bars and spring flats that will be hot-coiled or later heat treated; hard and scaled, not for direct use. | 600 | 1,000 | 12 | 30 HRC | 6.6 % IACS |
austenitised ≈900 °C, air cooled | Use to homogenise structure and refine grain after forging, ahead of final quench and temper. | 620 | 930 | 18 | 27 HRC | 6.6 % IACS |

oil quenched, tempered 650 °C | Softest quenched-and-tempered condition; used when machining after heat treatment or maximum ductility is required. | 880 | 1,010 | 15 | 31 HRC | — |
oil quenched, tempered 540 °C | Tough, high-yield condition for torsion bars and heavy sections where impact matters more than peak hardness. | 1,180 | 1,280 | 12 | 40 HRC | — |
Quenched and tempered | The standard working condition for leaf and coil springs: maximum elastic limit with usable toughness (~45–48 HRC). | 1,500 | 1,610 | 8 | 47 HRC | — |
Spring temper with compressive surface treatment | Standard for production leaf/coil springs: peening restores fatigue life lost to decarburisation and surface flaws. | 1,500 | 1,610 | 8 | 47 HRC | 6.4 % IACS |
oil quenched, tempered 315 °C | Near-peak strength with slightly better toughness than a 205 °C temper; watch for temper embrittlement range. | 1,720 | 1,980 | 5 | 53 HRC | 6.6 % IACS |

Working with 9260 Cold Drawn
Is 9260 easy to machine?
Machine only in the annealed/spheroidised state (~55 % of 1212) with rigid setups and sharp carbide; above 45 HRC use grinding, EDM or CBN turning.
Can 9260 be welded?
Poor weldability — carbon equivalent ≈0.9; if unavoidable, preheat 300–400 °C, low-hydrogen consumables, immediate post-weld temper, and accept loss of spring temper in the HAZ.
Can 9260 be formed, bent or molded?
Hot form or coil at 900–1000 °C, or cold coil in the annealed condition then oil quench from 860–880 °C and temper 400–500 °C; protect against decarburisation with controlled atmosphere or salt bath.
What surface finishes work on 9260?
No native corrosion resistance: shot peen then phosphate + oil, paint/powder coat, or Zn/Zn-Ni plate with a 190–220 °C hydrogen-relief bake; do not anodize.

9260 Cold Drawn — frequently asked
What is 9260 Cold Drawn used for?
9260 Cold Drawn is typically used for automotive leaf springs, coil springs, torsion bars, heavy-truck suspension springs, spring clips and retaining clips and agricultural tines and harrow springs. In short: premium spring bar.
What is the yield strength of 9260 Cold Drawn?
9260 Cold Drawn has a typical yield strength of 800 MPa (116 ksi) and a tensile strength of 950 MPa (138 ksi) — stronger than 86% of steel grades. Strength varies by condition: see the 9 listed tempers.
Is 9260 Cold Drawn easy to machine?
Not especially — machinability is rated fair (42/100, worse than 73% of steel grades). Machine only in the annealed/spheroidised state (~55 % of 1212) with rigid setups and sharp carbide; above 45 HRC use grinding, EDM or CBN turning.
Can 9260 Cold Drawn be welded?
Not readily — weldability is rated poor (18/100). Poor weldability — carbon equivalent ≈0.9; if unavoidable, preheat 300–400 °C, low-hydrogen consumables, immediate post-weld temper, and accept loss of spring temper in the HAZ.
What surface finishes work on 9260 Cold Drawn?
No native corrosion resistance: shot peen then phosphate + oil, paint/powder coat, or Zn/Zn-Ni plate with a 190–220 °C hydrogen-relief bake; do not anodize.
Can 9260 Cold Drawn be formed, bent or molded?
Hot form or coil at 900–1000 °C, or cold coil in the annealed condition then oil quench from 860–880 °C and temper 400–500 °C; protect against decarburisation with controlled atmosphere or salt bath.
What is the maximum service temperature of 9260 Cold Drawn?
9260 Cold Drawn is rated for continuous use to about 250°C (482 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
Can FabDigit make parts in 9260 Cold Drawn?
Yes — 9260 Cold Drawn is available for CNC machining and sheet metal; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
