Steel and types of Steel
Steel is basically iron + carbon, but small changes in composition and heat treatment create very different types. Here’s the breakdown that actually matters in the workshop and on site:

1. *By Carbon Content*
This is the most common way to split them up:

- *Low Carbon Steel / Mild Steel* – 0.05% to 0.25% carbon
Soft, ductile, easy to weld and bend. Used for structural beams, sheet metal, car bodies, pipes.
Example: A36 steel, the stuff you see in construction.

- *Medium Carbon Steel* – 0.25% to 0.60% carbon
Stronger and harder than mild steel, but harder to weld. Used for gears, axles, shafts, rails.
Example: 1045 steel.

- *High Carbon Steel* – 0.60% to 1.0% carbon
Very hard, high strength, but brittle. Used for cutting tools, springs, wires, knives.
Example: 1095 steel.

2. *By Alloying Elements*
When you add other elements, you get alloy steels:

- *Carbon Steel* – Only iron and carbon. Cheap, but will rust and loses strength at high temp.
- *Alloy Steel* – Add chromium, nickel, molybdenum, vanadium, etc.
Gives you better strength, toughness, wear resistance, and corrosion resistance.
Example: 4140 chromoly steel used for automotive parts and tools.
- *Stainless Steel* – At least 10.5% chromium. Forms a passive oxide layer that resists rust.
Subtypes:
- _304_: Most common, good corrosion resistance, used for kitchen gear, tanks.
- _316_: Adds molybdenum, better for marine/chemical environments.
- _430_: Ferritic, magnetic, cheaper, used for appliances.

3. *By Microstructure / Heat Treatment*
This is how metallurgists classify them:

- *Ferritic Steel*: Magnetic, good corrosion resistance, lower strength. Used in exhaust systems.
- *Austenitic Steel*: Non-magnetic, very corrosion resistant, good formability. Most stainless falls here.
- *Martensitic Steel*: Hard, strong, magnetic. Made by quenching. Used for knives, turbine blades.
- *Duplex Steel*: Mix of austenite and ferrite. High strength + corrosion resist
