What is E295-QT?
E295-QT is E295 heat treated to QT — optional water/oil quench and high temper for shafts and pins needing higher yield and toughness than as-rolled. E295-QT has a yield strength of 430 MPa (62.4 ksi) and a tensile strength of 660 MPa (95.7 ksi) — weaker than 51% of steel grades. Elongation at break is 17% and the elastic modulus is 210 GPa (30.5 Msi). E295-QT has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,450°C (2,642 °F). AR is the default condition FabDigit quotes; QT is available on request or by drawing note.

Working with E295-QT
Is E295 easy to machine?
Good general machinability at ~60 % of AISI 1212; turns and drills cleanly in normalized or cold-drawn condition, use carbide at 120–200 m/min with flood coolant.
Can E295 be welded?
Weldable only with care — carbon level is not capped, so preheat 100–200 °C, low-hydrogen electrodes and slow cooling are advised for sections above ~20 mm.
Can E295 be formed, bent or molded?
Hot forge/roll at 1100–850 °C; cold bending is limited (use generous bend radii ≥2t) and cold-drawn bar should be stress relieved before heavy machining.
What surface finishes work on E295?
No inherent corrosion resistance — protect with paint primer, zinc plating/galvanizing, phosphate + oil or black oxide; not anodizable.

E295-QT — frequently asked
What is E295-QT used for?
E295-QT is typically used for shafts, keys and pins, gears (low duty), machine housings and general mechanical parts. In short: strongest of the E-series; good machinability, limited welding; unalloyed machine-part bar.
What is the yield strength of E295-QT?
E295-QT has a typical yield strength of 430 MPa (62.4 ksi) and a tensile strength of 660 MPa (95.7 ksi) — weaker than 51% of steel grades. Strength varies by condition: see the 6 listed tempers.
Is E295-QT easy to machine?
Reasonably — machinability is rated good (55/100, better than 62% of steel grades). Good general machinability at ~60 % of AISI 1212; turns and drills cleanly in normalized or cold-drawn condition, use carbide at 120–200 m/min with flood coolant.
Can E295-QT be welded?
With care — weldability is rated fair (35/100). Weldable only with care — carbon level is not capped, so preheat 100–200 °C, low-hydrogen electrodes and slow cooling are advised for sections above ~20 mm.
What surface finishes work on E295-QT?
No inherent corrosion resistance — protect with paint primer, zinc plating/galvanizing, phosphate + oil or black oxide; not anodizable.
Can E295-QT be formed, bent or molded?
Hot forge/roll at 1100–850 °C; cold bending is limited (use generous bend radii ≥2t) and cold-drawn bar should be stress relieved before heavy machining.
What is the maximum service temperature of E295-QT?
E295-QT 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.
What is the difference between E295-AR and E295-C?
AR is the default condition — standard stock condition for bar, plate and sections; use when only the EN 10025-2 minimum strength is required. C: cold-drawn bar for close tolerance, bright surface and higher strength shafts/pins on automatics. Yield strength is 305 MPa in AR versus 460 MPa in C.
