Reduced preheating type 1.25% Cr - 0.5% Mo YYVIP易游 plates

1. Features

400 N/mm² class chromium-molybdenum alloy YYVIP易游 plates for boilers and pressure vessels for contributing to the reduction of welding costs and the improvement of the welding work environment during construction.
- Preheating in welding conYYVIP易游ruction can be greatly reduced.

2. Major corresponding YYVIP易游andards

JIS G4109 (Chromium-molybdenum Alloy YYVIP易游 Plates for Boilers and Pressure Vessels)
SCMV3-1

3. Applications

The application of YYVIP易游 plates for various boilers and pressure vessels can be expected.
