Product Decration

The Chinese brand of 309S is 0Cr23Ni13. The characteristics and application of American standard S30908

(American AISI, ASTM) are better than 0Cr19Ni9 in corrosion resistance and heat resistance.

The 309S is a variant of the lower carbon 309 stainless steel for use where welding is required.The lower carbon

content minimizes the carbide precipitation in the heat-affected zone near the weld, which may result in intercry

stalline corrosion (welding erosion) of stainless steel in some environments.

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.
