Corten B under ASTM Weathering Steel plate’s Copper Brittle Defect Control

Corten B under ASTM Weathering Steel plate’s Copper Brittle Defect Control

The general precautions for copper brittleness of ASTM Corten B weathering steel plate are:

 

1. Optimization of heating process and reasonable sequencing can avoid the accumulation and accumulation of copper in ASTM Corten B weathering steel during heating, thus reducing the occurrence of copper brittle defects.

2. Furnace time has a great influence on the copper brittleness of ASTM Corten B weathering steel. The longer the furnace time, the more favorable the diffusion of copper along the grain boundary, and the easier it is to form cracks like cracks or bubbles like copper brittleness. The data shows that the furnace temperature is generally controlled within 360 min, which is more suitable. When the furnace time is > 360min, the thin gauge product should be modified. Otherwise, the slab should be removed and withdrawn.

3 The temperature should be controlled at <1210 ° C or higher than 1280 ° C. When the oven temperature is 1210-1280 ° C, the order of thickness is preferably less than 3.3 mm.
