The key delivery finishes of stainless steel coil or strip or sheet
2E
Surface overview: Hot rolled black skin coils are used to directly roll the black skin through a continuous rolling production line, and then undergo solution annealing, phosphorus breaking and electrolytic pickling to form the surface. The surface has low roughness and good surface quality, providing stable and reliable blanks for subsequent orders for "special materials" and cold-rolled thin materials.
Process route: hot-rolled black skin coil—black skin straight rolling—annealing—phosphorus breaking—pickling—coil/plate finished product
Covered steel grades: 200 series, 300 series, 400 seriesThickness range: 1.0mm-3.0mm
2D
Surface overview: After the material is cold-rolled and rolled, the strip is continuously annealed to change the structure and the mechanical properties of the material to meet the mechanical properties required by the customer; then electrolysis and pickling are used to remove the oxidized scale on the surface of the steel strip, and then subjected to drawing Correct the plate shape.
Process route: raw material NO.1/2E—rolling—degreasing cleaning—annealing—electrolysis—pickling—stretching and straightening—finished coil/plate
Covered steel grades: 200 series, 300 series, 400 series
Thickness range: 0.25mm-3.0mm
2B
Surface overview: After the material is cold-rolled and rolled, the strip is continuously annealed to change the structure grain and the mechanical properties of the material to meet the mechanical properties required by the customer; then electrolysis and pickling are used to remove the oxide scale on the surface of the steel strip, and then adjusted Quality rolling and stretching corrects the plate shape and enhances the surface fineness.
Process route: raw material NO.1/2E—rolling—degreasing cleaning—annealing—electrolysis—pickling—tempering and rolling—stretching and straightening—finished coil/plate
Covered steel grades: 200 series, 300 series, 400 series
Thickness range: 0.25mm-3.0mm
BA
Surface overview: After 2E material is rolled by high-precision 20-roll cold rolling, degreasing and bright annealing production lines are used to make the strip annealed in an oxygen-free environment to change the structure, grain and mechanical properties of the material to meet the mechanical properties required by the customer; Quenched and tempered rolling to correct the shape and improve the surface fineness.
Process route: raw material 2E—20 roll rolling—vertical/horizontal bright annealing—tempered and tempered rolling—coil/plate finished product
Covered steel grades: 200 series, 300 series, 400 series
Thickness range: 0.25mm-1.5mm
