# Metals - Strength vs. Temperature

The diagram below indicates the influence of temperature on the strength of

• bronze
• copper
• structural steel
• castings steel
• cast iron
• wrought iron
• stainless steel (304N)

.

### Strength of Metals - Imperial Units

Most ferrous metals have their maximal strength at about 200 oC (400 oF). Modulus of elasticity decreases gradually with increased temperature until it rapidly falls off.

#### Example - Strength of Copper at 100 oC

As indicated in the first figure - the strength of copper is reduced to approximately

95 % at 100 oC

With an Ultimate Tensile Strength - σu - of 220 MPa for copper - the strength is reduced to

0.95 (220 MPa)

= 209 MPa
