Core storage risks of stainless steel strips: iron ion contamination, rust, moisture pitting, surface scratches, coil deformation, mixed material errors, label loss. Once rust spots appear on austenitic stainless steel, they are difficult to remove.
Fundamental problem: Iron ion pollution (free iron pollution) causes induced corrosion on the surface of stainless steel, rather than the corrosion resistance failure of the stainless steel material itself.
Stainless steel hot-rolled surface is not suitable for directly producing exposed finished products. Its advantages are thick thickness, low cost, and high substrate strength, making it suitable for working conditions that require subsequent cutting, forming, and precision machining.
Divided into two categories: hot-rolled stainless steel coils and cold-rolled stainless steel coils (2B/BA, etc.) The mainstream route of steel mills: electric arc furnace smelting → AOD refining → continuous casting billet → hot rolling (producing hot-rolled coils); Hot rolled coils are used as raw materials and then enter the cold rolling process to produce cold-rolled stainless steel coi
Classify and organize according to new energy, traditional electricity, oil and gas petrochemicals, hydrogen energy, and nuclear power, and distinguish three types of uses: ultra-thin precision steel strips, structural bundling steel strips, and heat-resistant conveyor steel strips:
