What are the shortcomings of carbon steel plate

(1) Low hardenability. Under normal circumstances, the maximum quenching diameter of carbon steel water quenching is only 10mm-20mm.

(2) The strength and yield ratio of carbon steel plate are low.

(3) The tempering stability of carbon steel plate is poor. Due to poor tempering stability, low tempering temperature is required to ensure high strength of carbon steel during quenching and tempering treatment, so the toughness of steel is low; in order to ensure better toughness, the strength is low when high tempering temperature is adopted, so the comprehensive mechanical performance level of carbon steel is not high.

(4) The of carbon steel plate cannot meet the requirements of special performance. Carbon steel is often inferior in terms of oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, abrasion resistance, and special electromagnetic properties, which cannot meet the needs of special performance.
