Stainless Steel Classifications

Overview

Engineering reference data for Stainless Steel Classifications in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Variables

Selection Criteria for Stainless Steels

Selection of stainless steels is generally based on the following factors:

• Corrosion resistance
• Fabrication characteristics
• Availability
• Mechanical properties for specific temperature ranges
• Product cost
