View JIS G3445 Grade STKM13C Manufacturing Process
STKM13C is manufactured using several techniques, including forging, hot rolling, cold rolling, casting, and extrusion. Each method contributes to the material’s unique properties and suitability for specific applications.
STKM13C Manufacturing Process
Forging is typically performed at temperatures ranging from 2012°F to 2192°F, allowing the material to be molded and shaped under high pressure. Hot rolling involves heating the steel to 2000°F to 2400°F, making it malleable before passing it through rollers to achieve the desired dimensions. Cold rolling enhances strength and surface finish, while casting involves melting the steel at 2597°F to 2804°F and pouring it into molds to create the final shape.
