CHROMECORE 414Pinch-S

CLASSIFICATION

EN 14700 T Fe7

DESCRIPTION

• Tubular wire for submerged arc cladding steel mill rolls
• Weld deposit gives high hardness and wear resistance at elevated temperature with excellent thermal fatigue resistance

APPLICATIONS

• Chromecore 414Pinch-S has been developed specifically for depositing onto steel mill pinch rolls, a weld metal that increases in hardness combined with maximum resistance to wear by corrosion, fire cracking and pick up.
• Chromecore 414Pinch-S is most suitable for hardfacing of lower and upper Pinch rolls in hot strip mills.
