Heat-resistant flat bar steel

详情

Steel contain some alloying element, such as add P, Cu, Cr, Ni, Mo......Under the condition of temperature in the self-protection of the oxide film is formed on the base metal can enhance its resistance to atmospheric corrosion.

Heat-resistant steel

- standard (EN ******5);

- mark s (Structura steel);

- the thickness of *6 mm or less minimum yield strength of the logo, expressed in MPa;

- related to impact the quality of the numerical identification;

- the letters W said atmospheric corrosion resistant steel;

- if necessary, P said high phosphorus content level (only applicable to level S**5);
