Table of Different Steels
Carbon (C) | 1. Increases edge retention and raises tensile strength 2. Increases hardness and improves resistance to wear and abrasion |
Chromium (Cr) | 1. Increases hardness, tensile strength and toughness 2. Provides resistance to wear and corrosion |
Cobalt (Co) | 1. Increases strength and hardness and permits
quenching in higher temperatures 2. Intensifies the individual effects of other elements in more complex steels |
Copper (Cu) | 1. Increases corrosion resistance 2. Increases wear resistance |
Manganese (Mn) | 1. Increases hardenability, wear resistance and tensile strength 2. De-oxidizes and de-gasifies to remove oxygen from molten metal 3. In larger quantities, increases hardness and brittleness |
Molybdenum (Mo) | 1. Increases strength, hardness, hardenability, and toughness 2. Improves machinability and resistance to corrosion |
Nickel (Ni) | 1. Adds strength, hardness and corrosion resistance |
Phosphorous (P) | 1. Improves strength, machinability and hardness 2. Creates brittleness in high concentrations |
Silicon (Si) | 1. Increases yield strength 2. Increases tensile strength 3. De-oxidizes and de-gasifies to remove oxygen from molten metal |
Sulphur (S) | 1. Improves machinability when used in minute quantities |
Tungsten (W) | 1. Adds strength, toughness and hardness |
Vanadium (V) | 1. Increases strength, hardness and resistance to shock impact 2. Retards grain growth |
