[Clouds Steel Works to recommend the star product - steel production] 3, forming performance of cold-formed steel is a measure of the performance of the steel bent at room temperature process to produce plastic deformation resistance when cracks. Cold bending properties of the steel is subjected to cold-formed steel experiment to test the performance of a predetermined degree of bending of the bending deformation. [Clouds Steel Works to recommend the star product - steel production] 5 weldability weldability of steel refers - under given welding conditions, access to good properties of welded joints. Welding performance can be divided into two welding performance welding process welding properties and performance. Welding process welding performance refers to the welding process welds and weld metal is not close to thermal cracking or cooling does not produce cooling shrinkage cracking sensitivity. Welding performance is good wood attic price, is that under certain conditions the welding Wood Attic company, close to the base metal and weld metal are not cracks. Welding performance on the use of performance refers to the impact toughness of welds and heat affected zone ductility required mechanical properties of weld metal and heat affected zone is not less than the mechanical properties of the steel base material. Welding performance test methods of welding process, also used welding performance test method on the use of the use of nature.
