So how do we prevent surface cracks in 316 stainless steel angle?

1, to reduce and avoid folding to produce cracks: reasonable design of the hole type, eliminate the ears of the finished pre-rolled parts; accurate design of the wide spreading, accurate adjustment of the roller groove position, to reduce or eliminate the flying edge, scraping and other defects.

2, to reduce inclusions in steel to produce cracks: the use of reasonable deoxidation alloying process, strict control of steel oxygen content, reduce the content of steel inclusions.

3, to reduce the subcutaneous bubbles produce cracks: the entire protection of the pouring process, to avoid secondary oxidation of the steel, reduce the bubble generation, improve the purity of the cast billet; reasonable control of continuous casting steel superheat, choose the physical and chemical properties of excellent protection slag, take uniform cooling and secondary weak cooling, to avoid cracks on the surface of the cast billet.
