Purpose
• To find out what steel alloying

3.

Plan
• Alloying
• Improvement of properties
• Changing properties
• Purpose of alloying
• Used elements
• Examples of steel alloying

4.

Alloying
Adding impurities to the composition to
change (improve) the physical and/or
chemical properties of the base material

5.

Improvement of properties
• Mechanical properties
• Physical properties
• Chemical properties

6.

Changing properties
• Increase in hardness
• Increased wear resistance
• Increased corrosion resistance

7.

Purpose of alloying
Improving the quality of
metallurgical products

8.

Used elements
• Chromium (Cr)
• Manganese (Mg)
• Nickel (Ni)
• Tungsten (W)
• Vanadium (V)
• Niobium (Nb)
• Titanium (Ti)

9.

Examples of steel alloying
Cadmium + copper = wear resistance
Zinc + copper/bronze = strength, ductility,
corrosion resistance
Titanium + molybdenum = temperature limit

10.

Conclussion
• Alloying
• Improvement of properties
• Changing properties
• Purpose of alloying
• Used elements
• Examples of steel alloying
