Surface Finish of stainless steel bar

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

UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate.
The addition of copper to this grade gives it corrosion resistant properties superior to the conventional chrome nickel stainless steels, in particular to sulphuric, phosphoric and acetic acids. However, there is limited use with hydrochloric acids. It also has a high resistance to pitting in chloride solutions, a high resistance to both crevice and stress corrosion cracking. Alloy 904L performs better than other austenitic stainless steels due to the higher alloying of nickel and molybdenum.
The grade is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.
The high chromium content promotes and maintains a passive film which protects the material in many corrosive environments.904L has a greater resistance to precipitation of ferrite and sigma phases on cooling and welding than other stainless steels containing molybdenum such as 316L and 317L. There is no risk of intercrystalline corrosion on cooling or welding due to the low carbon content. Its maximum service temperature is at 450°C.
This grade is particularly useful in control and instrumentation tubing applications where 316 and 317L are not suitable.
