Product Decration

317L(00Cr19Ni13Mo3, UNS S31726) alloy is an austenitic stainless steel based on molybdenum.Compared with

conventional chromium-Nickel austenitic stainless steel such as 304 alloy, it is more resistant to chemical corrosion.

In addition, 317L alloys have higher ductility, stress corrosion resistance, compression strength and high temperature

resistance than conventional stainless steels.It is low carbon or L grade, which has resistance to sensitization during

welding and heat treatment.

Compared with 316L, 317L steel has good seawater resistance and SCC resistance, which is used in Chemical

Reactor and other Chemical equipment requiring high corrosion resistance.

Definition of BA products

The definition of JIS standard is the surface after cold rolled bright annealing, which is called BA. The definition of

GB is also the surface after cold rolled bright annealing, but the product standard of BA is no different from 2B, such

as JIS, ASTM, GB, etc.As the NO. 9.

Surface classification of BA products

Since the surface grade of BA is different, the gloss of its surface is also different, so all levels cannot be allocated

to users as 2B.The grade 2B is classified according to the surface defects, and the surface color and other states

are identical regardless of the grade.For BA products, different grades not only have different defects, but also have

different surface states. Therefore, BA products are classified according to the surface color and luster and divided

into various grades.The size of the cold rolling rate directly determines the luster of the BA plate surface, so the luster

of the general thin material is better than the thick material.

BA product gloss

The luster of BA products is mainly reflected in three aspects: resolution, amaurosis and color.1) Resolution: The

resolution is the image clarity of the object on the strip surface. The better the resolution, the clearer the image will be.

2) Amaurosis: a kind of white bad state on the surface of the strip, mainly manifested in the overall roughness of the

surface.The light on the surface of the strip is in a state of random reflection, which looks like a white haze.Only SUS430

steel is required.As the steel character of SUS304 is silver-white, general amaurosis is not required, while S430 is strictly

required.3) Coloring: refers to the strip surface is brown or blue bad state.The thickness of the oxide film on the surface,

so that the light reflected in the human eye takes on different colours according to the wavelength of reflection.Under

normal circumstances unless the unit accident, otherwise the coloring can be guaranteed.The luster of BA products is

the comprehensive embodiment of the three aspects.General resolution is good, white meng is good.The glossiness at

this time also is good.For SUS304, high image resolution requirements, such as watchband, turning mirror, battery tube,

car window frame, etc., while sink, pipe, equipment and other requirements are low.The applications of SUS430 image

resolution are radiator reflector, car window frame, washing machine cylinder, car lamp reflector, etc.White amaurosis is

relatively speaking, the situation that the solution image asks high, white amaurosis also asks high, if face plate, home

appliance exterior board, beer cover, frozen shelf, asphalt board, bicycle fender, etc.

Surface Feature Summary of manufacturing method Application
NO.1 Silver white matt A rough, matte surface that is hot rolled to a specified thickness, then annealed and descaled Does not require surface gloss
NO.2D silver white Heat treatment and pickling after cold rolling 2D products are used for applications that do not require strict surface requirements, general materials, and deep drawing materials
NO.2B Gloss is stronger than NO.2D After NO.2D treatment, the final pass is lightly cold rolled by polishing rollers General materials
BA Bright as a mirror There is no standard, but it is usually bright annealed surface processing, with high surface reflectivity. Building materials, kitchen utensils
NO.3 Rough grinding Use 100~200# (unit) grinding belt for grinding Building materials, kitchen utensils
NO.4 Intermediate grinding Polished surface obtained by grinding with 150~180# abrasive belt Same as above
NO.240 Fine grinding Grinding with 240# grinding belt Kitchenware
NO.320 Very fine grinding Grinding with 320# grinding belt Same as above
NO.400 Gloss close to BA Use 400# polishing wheel for grinding General timber, construction timber, kitchen utensils
HL Hairline grinding Grinding the hairline with the appropriate particle size abrasive material (150~240#) has a lot of grains Buildings, construction materials
NO.7 Close to mirror polishing Use 600# rotary polishing wheel for grinding For art and decoration
NO.8 Mirror grinding Mirror grinding with polishing wheel Reflector, for decoration
