Low Hydrogen
Metal degassing at low pressure, and the creation of adapted slag enables us to obtain hydrogen content down to 1ppm through a vacuum pouring process.
Sulphur content
• Appropriate metal and slag deoxidation enables us to produce low sulphur aims under 10ppm sulphur content.
• For grades with aimed sulphur, calcium treatment is used to obtain globular inclusion in order to facilitate machining.
Inclusion cleanliness
The specific steel plant facilities (furnace, LF, VD/VOD), and process control guarantee very low oxygen content and
