How to control the cutting quality of p235gh boiler steel process?

Pageviews:

The steel plate is a flat steel that is poured with molten steel and pressed after cooling. The steel plate is flat and rectangular, and can be directly rolled or cut from a wide steel strip. The P235GH boiler steel process product cut parts have high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low temperature impact toughness.

Sulfur is a very harmful element in p235gh boiler steel process steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of p235gh boiler steel process steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
