Product Description

AISI 1035 Carbon Steel Overview

AISI 1035 is a medium-carbon steel grade characterized by its excellent balance of strength, ductility, and toughness. Unlike highly alloyed steels, 1035 relies primarily on its carbon content ($0.32\% - 0.38\%$) to achieve its mechanical properties, making it a cost-effective choice for structural and automotive applications.

Technical Specifications

Common Available Formats

• Round Bars: Typically hot-rolled or cold-drawn, used heavily in machining and shaft production.

• Rods: Often supplied in coils or straightened lengths for forging or wire-drawing applications.

• Precision Ground Bars: For applications requiring tight dimensional tolerances and a high-quality surface finish.

International Equivalents

When sourcing globally, AISI 1035 is frequently cross-referenced with the following standards:

• DIN/EN (Germany/Europe): 1.0501 or C35

• AFNOR (France): XC35

• JIS (Japan): S35C

• BS (UK): 060A35

• UNI (Italy): C35

Heat Treatment and Machinability

AISI 1035 responds well to several thermal processes:

1. Forging: Should be performed between 950°C and 1230°C.

2. Annealing: Heated to 840–890°C followed by slow furnace cooling to improve machinability.

3. Hardening: Quenched in water or oil from a temperature of 840–870°C.

4. Machinability: Rated at approximately 70% of AISI 1112 (the standard free-machining carbon steel).

Key Applications

Because of its versatility, 1035 is commonly found in:

• Automotive: Levers, bolts, nuts, and studs.

• Industrial: Gears, axles, and crankshafts where moderate strength is required.

• Construction: Tie rods and structural support pins.
