Cold Work Steel

Description
BÖHLER K340 ISODUR, an 8% chromium steel, is produced using the electro-slag remelting (ESR) method. This by BÖHLER developed and proven remelting technology, ensures extremely low micro and macro segregations and gives the material the purity and homogeneity necessary for excellent performance in practice.

Property Features
Key reasons for the broad application spectrum of BÖHLER K340 ISODUR:

• Outstanding toughness
• Excellent compressive strength
• Very good machinability due to homogeneous structure
• Smaller dimensional changes

BÖHLER K340 ISODUR is particularly suitable for the following application areas:

• Cutting
• Blanking
• Cold forming
