SAE 1018 1020 1022 Carbon Steel Hot Rolled Alloy Steel Wire Rod 5.5mm 6.5mm

AISI 1018 mild/low carbon steel has excellent weldability and produces a uniform and harder case and it is considered as the best steel for carburized parts. AISI 1018 mild/low carbon steel offers a good balance of toughness, strength and ductility. Provided with higher mechanical properties, AISI 1018 hot rolled steel also includes improved machining characteristics and Brinell hardness.

GRADE

CHEMICAL COMPOSITION

WELDABLITY

This grade is easily welded by all the welding processes, and the resultant welds and joins are of extremely high quality. The grade of welding rod to be used depends upon the thickness of section, design, service requirements and so on.

HARDENING

This grade will respond to any of the standard carburizing methods and subsequent heat treatments. For a hard case and tough core, the following heat treatment is suggested: carburize at 1650 – 1700 degree Fahrenheit for approximately eight hours, cool in box and reheat to 1400 – 1450 degree Fahrenheit quench in water and drawn at 300 – 350 degree Fahrenheit.

HEAT TREATMENT

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

• Normalizing
• Forging
• Tempering
• Annealing
• Stress Relieving
• Case Hardening
• Core Refining
• Carburizing
