What is 1035 Normalized?
1035 Normalized is 1035 heat treated to Normalized — standard condition for forgings and weldments: uniform fine grain, good strength/toughness balance without quench distortion. 1035 Normalized has a yield strength of 345 MPa (50 ksi) and a tensile strength of 550 MPa (79.8 ksi) — weaker than 75% of steel grades. Elongation at break is 28% and the elastic modulus is 205 GPa (29.7 Msi). 1035 Normalized has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,425°C (2,597 °F). HR is the default condition FabDigit quotes; Normalized is available on request or by drawing note.

Working with 1035 Normalized
Is 1035 easy to machine?
Machines well at ~65 % of 1212 with carbide or HSS; normalized or Q&T structure gives cleaner chips than annealed, and free-cutting is limited by low sulphur.
Can 1035 be welded?
Weldable by SMAW/GMAW with low-hydrogen consumables; preheat 100–200 °C for sections above ~20 mm and post-weld stress relieve to avoid HAZ hardening and cracking.
Can 1035 be formed, bent or molded?
Hot forges readily at 1100–1200 °C; cold bending only in annealed/hot-rolled state with generous radii (≥2t), since 0.35 % C limits cold formability.
What surface finishes work on 1035?
No inherent corrosion protection — specify phosphate + oil, zinc plate, blackening or paint; takes chrome plating, nitriding and induction hardening well and polishes to a fair bright finish.

1035 Normalized — frequently asked
What is 1035 Normalized used for?
1035 Normalized is typically used for forged gears, hand tools and bolts. In short: standard carbon steel.
What is the yield strength of 1035 Normalized?
1035 Normalized has a typical yield strength of 345 MPa (50 ksi) and a tensile strength of 550 MPa (79.8 ksi) — weaker than 75% of steel grades. Strength varies by condition: see the 7 listed tempers.
Is 1035 Normalized easy to machine?
Reasonably — machinability is rated good (60/100, better than 83% of steel grades). Machines well at ~65 % of 1212 with carbide or HSS; normalized or Q&T structure gives cleaner chips than annealed, and free-cutting is limited by low sulphur.
Can 1035 Normalized be welded?
Yes — weldability is rated good (58/100). Weldable by SMAW/GMAW with low-hydrogen consumables; preheat 100–200 °C for sections above ~20 mm and post-weld stress relieve to avoid HAZ hardening and cracking.
What surface finishes work on 1035 Normalized?
No inherent corrosion protection — specify phosphate + oil, zinc plate, blackening or paint; takes chrome plating, nitriding and induction hardening well and polishes to a fair bright finish.
Can 1035 Normalized be formed, bent or molded?
Hot forges readily at 1100–1200 °C; cold bending only in annealed/hot-rolled state with generous radii (≥2t), since 0.35 % C limits cold formability.
What is the maximum service temperature of 1035 Normalized?
1035 Normalized is rated for continuous use to about 425°C (797 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1035-HR and 1035-IH?
HR is the default condition — default stock condition for bar, plate and forging blanks where scale and ±loose tolerance are acceptable. IH: select when a wear-resistant 50–58 HRC skin is needed on a tough normalized or Q&T core, e.g. shaft journals and guide rails. Yield strength is 320 MPa in HR versus 550 MPa in IH.
