The steel manufacturing process begins with cast iron, removing its impurities of this, and reducing the percentage of the principal component of the alloy that is coal.

1. About
Steel Testing

2. Steel Testing
• Steel is probably one of the most essential materials in
the record of the last millennium, and probably the most
essential in the XXI millennium.
• Steel is an alloy of iron and carbon, which carbon is
present in a percentage less than 2%.
• The steel manufacturing process begins with cast iron,
removing its impurities of this, and reducing the
percentage of the principal component of the alloy that
is coal.

3. • Tensile testing performed on a stainless steel tensile
specimen to failure using a computerized tensile test
machine.
• An extensometer measures yield strength at
different loads. These measurements are used to
compute strain.
