If the silicon content in the steel exceeds 0.50-0.60%, silicon is considered an alloy element. Silicon can significantly enhance the elastic limit, yield point, and tensile strength of the steel, making it widely used for spring steel. By adding 1.0-1.2% silicon to quenched and tempered structural steel, its strength can be increased by 15-20%.

11. Decline of the Bessemer Process In spite of the basic simplicity, the Bessemer steel suffered from several limitations: • A large part of the heat generated through exothermic reactions is lost in the form of sensible heat of the N2 gas. So, the scrap melting ability of this process is very limited. • The 'N' content in the Bessemer steel is …
