304 stainless steel strip and slit to width coil, ASTMA-666, is similar to Type 302, but has a maximum carbon content of 0.08%. This material has an excellent combination of corrosion resistance and formability. 304 is also known as 18/8 chrome-nickel, austenitic, stainless strip. It is a versatile alloy that welds well without filler. It’s commonly used in stampings and drawn parts. It’s non-magnetic in the annealed state and become magnetic with work hardening. Gibbs Interwire stocks Type 304 annealed stainless strip in gauges from 0.0053″ and 304 tempered strip in gauges from .0019".
Surface Finish of stainless steel coil | |
Surface Finish | Definition and Application |
No.1 | The surface is finished by heat treatment and pickling or processes corresponding theretoafter hot rolling |
2D | The finishes after cold rolling, by heat treatment, pickling or other equivalenttreatment |
2B | The finish after cold rolling, by heat treatment, pickling or other equivalent treatment and lastly by cold rolling to give an appropriate luster |
BA | Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror |
NO.3 | Polished with abrasive belt of grit#100~#200,have better brightness with discontinuous coarse stria |
NO.4 | Polished with abrasive belt of grit#150~#180,have better brightness with discontinuous coarse stria |
HL | Polished with abrasive belt of grit#150~#320 on the NO.4 finish and has continuous streaks |
8K | The product have excellent brightness and prefect reflexivity can be the mirror |
