Cold-Drawn BS 1387 DIN 1626 Seamless ERW Steel Tube Thin Wall Pipe for Construction
Product Description:
The high frequency welding heat process of ERW steel tube causes the temperature distribution gradient near the edge of billet, and forms the characteristic regions such as melting zone, semi-melting zone, superheated structure, normalizing zone, incomplete normalizing zone and refiring zone. As the welding temperature in the superheated zone is above 1000℃, the austenite grains grow rapidly and form hard and brittle coarse crystal phase under cooling condition. In addition, the existence of temperature gradient will produce welding stress.
