Types

Mild steel 1018

Material type: Metal, Mild steel, low carbon
Mild steel 1018 is a widely used alloy with good machinability, weldability, toughness, strength, but it’s susceptible to corrosion on the surface.

Material advantages

Mild steel 1018 is a kind of low carbon steel, which has good strength and toughness. It has excellent weldability and it is considered the best steel for carburized parts.

Material shortcomings

Poor corrosion resistance.

Recommended description

Mild steel 1018 has excellent weldability, produces a uniform and harder case and it is considered the best steel for carburized parts. 1018 mild/low carbon steel offers a good balance of toughness, strength and ductility. 1018 hot rolled steel has significant mechanical properties, improved machining characteristics and has a high Brinell hardness measure.

Mild steel 1045

Material type: Metal, Mild steel, high strength
Mild steel 1045 is a medium tensile carbon steel with good strength and impact properties. It is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot-rolled condition.

Material advantages

1045 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot-rolled condition.

 Material shortcomings

Poor corrosion resistance. And the steel lacks suitable alloying elements and hence does not respond to the nitriding process.

Recommended description

Mild steel 1045 steel has good machinability in a normalized or hot-rolled condition. Operations like tapping, milling, broaching, drilling, turning and sawing can be carried out on 1045 steel using suitable feeds, tool type, and speeds.
