Machining

The machinability of AISI 1018 mild/low carbon steel is graded at 78% of B1112.

Weldability

AISI 1018 mild/low carbon steel can be instantly welded by all the conventional welding processes. Welding is not recommended for AISI 1018 mild/low carbon steel when it is carbonitrided and carburized.

Low carbon welding electrodes are to be used in the welding procedure, and post-heating and preheating are not necessary.
Pre-heating can be performed for sections over 50 mm. Post-weldstress relieving also has its own beneficial aspects like the pre-heating process.

Heat Treatment
The heat treatment for AISI 1018 mild/low carbon steel consists of the following processes:

Normalizing

AISI 1018 mild/low carbon steel should be heated at 890°C - 940°C and then cooled in stillair.

Forging
This process requires heating between 1150°C-1280°C and AISI 1018 mild/low carbon steeis held until the temperature becomes constant.900'C is the minimum temperature required for the forging process.The steel is then cooled in air after this process..
Tempering
AISI 1018 mild/low carbon steel is tempered at between 150°C- 200°C for improvement ofcase toughness. This process has little or no effect on hardness.The occurrence of grinding cracks is reduced when AISI 1018 mild/low carbon steel istempered at the above mentioned temperature.
Annealing
The AISI 1018 mild/low carbon steel is heated at 870°C - 910°C and allowed to cool in afurnaceStress Relieving
5009C-700°C is required to relieve stress in AISI 1018 mild/low carbon steel that is latercooled down in still air.
Case Hardening
This process requires heating to be carried out between 780°C- 820°C. AISI 1018 mild/lowcarbon steel is then quenched in water.

Core Refining
This is an optional process that requires heating at 880°C-920°C.
AISI 1018 mild/low carbon steel after being heated is moistened in oil or water.
Carburizing

Carburizing takes place at 880°C-920°C.

Applications of AISI 1018 Mild/Low Carbon Steel

• It is used in bending, crimping and swaging processes.
• Carburized parts that include worms, gears, pins, dowels, non-critical components of tool anddie sets, tool holders, pinions, machine parts, ratchets, dowels and chain pins use AISI 1018mild/low carbon steel.
• It is widely used for fixtures, mounting plates and spacers.It is suitably used in applications that do not need high strength of alloy steels and highcarbon.
• It provides high surface hardness and a soft core to parts that include worms, dogs, pins,liners, machinery parts, special bolts, ratchets, chain pins, oil tool slips, tie rods, anchor pinsstuds etc.
• It is used to improve drilling, machining, threading and punching processes.
• It is used to prevent cracking in severe bends
