Carbon steels have carbon as the key alloying element in their composition. They also contain up to 0.4% silicon and 1.2% manganese. In addition, the residual elements such as copper, molybdenum, aluminium, chromium and nickel are present in these steels. AISI 1035 carbon steel is a water resisting carbon steel whose wear resistance and hardenability are increased by the addition of small quantity of chromium.

1035 Carbon Steel Chemical Composition

The chemical composition of AISI 1030 carbon steel is outlined in the following table.

Max 0.38 0.9 0.04 0.05

① When carbon steel is required to specify the Si content, it is usually selected according to the following five grades: Si≤ 0.10%, 0.10%~0.20%, 0.15%~0.35%, 0.20%~0.40%, 0.30%~0.60%.

② When the content of copper and Cu is specified for carbon steel, Cu ≥ 0.2%.

③ When it is necessary to add lead Pb element to the standard steel, the specified range is 0.15%~0.35% (including 0.35%). Such steel is identified by inserting the letter L between the second and third digits of the grade name, for example 10L45. When lead Pb was added to the ladle, no thermal analysis was performed.

④ When boronization of killed steel is specified, the content of boron in the steel should reach 0.0005%~0.003%. Steel containing titanium is not allowed, and the upper limit of boron content can reach 0.005%.

⑤ When the supply and demand sides reach an agreement, bismuth, calcium, selenium or tellurium can be added to carbon steel.

1035 carbon steel is readily welded with the correct procedure. Welding in the through-hardened or flame or induction-hardened conditions is not recommended. Low-hydrogen electrodes are recommended together with preheat at 300-500ºF (150-260 ºC) to be maintained during welding, Cool slowly and stress relieve where possible.

1035 Carbon Steel Applications

1035 carbon steel is used for forged parts where the strength and toughness of the material are appropriate. C1035 may be used for the manufacture of links and couplings, gears, forged shafts and axles. It may also be used for the production, by open die forging, of such diverse parts as a 4,000 lb hub for a mining shovel.
