Compare all 8 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |

Annealed | Softest condition, chosen when heavy machining, cold forming or subsequent hardening is planned. | 310 | 560 | 24 | 160 HB | — |

Normalized | Choose for uniform fine-grain structure and better toughness/machining consistency in heavy sections before further machining. | 360 | 610 | 20 | 175 HB | 10 % IACS |
+QT | Tough, machinable condition for medium-loaded shafts and levers in thick sections where full hardening is impractical. | 470 | 700 | 18 | 18 HRC | 10 % IACS |
Cold drawn | Bright bar with tight tolerance and higher strength; pick for shafts and machined parts needing good surface without turning. | 560 | 700 | 10 | 210 HB | — |

What is E335?
E335 (1.0060) is a medium-carbon unalloyed engineering steel in the EN 10025-2 non-alloy family, with up to 0.50 % C giving moderate hardenability and a 335 MPa minimum yield strength. Engineers choose it for machine parts that need more strength than a structural grade without alloy cost; it is stocked as hot-rolled, normalized, annealed and cold-drawn bar and can be supplied quenched and tempered to 200 HB or 28–38 HRC, or induction hardened to 52 HRC. In the default condition it gives 355 MPa yield, 620 MPa tensile, 18 % elongation and 180 HB. Weldability is limited by a CEV of roughly 0.55–0.65 and it has no corrosion resistance; step up to E360 when higher hardness and wear resistance are required. E335 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,420°C (2,588 °F). E335 has a yield strength of 355 MPa (51.5 ksi) and a tensile strength of 620 MPa (89.9 ksi) — weaker than 73% of steel grades. Elongation at break is 18% and the elastic modulus is 210 GPa (30.5 Msi).

Working with E335
Is E335 easy to machine?
Machines well with carbide at ~120–180 m/min in the hot-rolled or annealed state; above 30 HRC drop speed and use rigid setups and coolant.
Can E335 be welded?
Weldable but crack-sensitive: CEV ≈ 0.55–0.65, so use low-hydrogen consumables, preheat 150–250 °C for t > 20 mm and consider post-weld stress relief at 550–650 °C.
Can E335 be formed, bent or molded?
Hot forge at 1100–850 °C then normalize; cold bending needs generous radii (≥3t) and is best done in the annealed condition.

What surface finishes work on E335?
No inherent corrosion resistance — phosphate + oil, zinc plating, hot-dip galvanizing (watch hydrogen embrittlement on hardened parts) or paint; polishes to a bright but non-durable finish.

E335 — frequently asked
What is E335 used for?
E335 is typically used for shafts and axles, bolts and studs, gears, couplings and machine tool components. In short: stronger than structural grades; through-hardenable to 38 HRC; low-cost shaft steel.
What is the yield strength of E335?
E335 has a typical yield strength of 355 MPa (51.5 ksi) and a tensile strength of 620 MPa (89.9 ksi) — weaker than 73% of steel grades. Strength varies by condition: see the 8 listed tempers.
Is E335 easy to machine?
Reasonably — machinability is rated good (55/100, better than 62% of steel grades). Machines well with carbide at ~120–180 m/min in the hot-rolled or annealed state; above 30 HRC drop speed and use rigid setups and coolant.
Can E335 be welded?
With care — weldability is rated fair (45/100). Weldable but crack-sensitive: CEV ≈ 0.55–0.65, so use low-hydrogen consumables, preheat 150–250 °C for t > 20 mm and consider post-weld stress relief at 550–650 °C.

What is the maximum service temperature of E335?
E335 is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
