說明 Characteristics. Weld metal deposited by ECoCr-B electrodes is similar in composition to ECoCr-A deposits except for a slightly higher carbide content (approximately 16%). The alloy also has a slightly higher hardness coupled with better abrasive and metal-to-metal wear resistance. Impact and corrosion resistance are lowered slightly.Deposits can be machined with carbide tools.
Applications. ECoCr-B electrodes are used interchangeably with ECoCr-A. Choice will depend on the specific application.
