430 stainless steel is a general steel type with good corrosion resistance. The heat conduction performance is better than that of Aochi. The thermal expansion coefficient is smaller than the auscultation, heat -resistant fatigue, adding stable elements titanium, and good mechanical performance of the weld site. 430 stainless steel is used for building decoration, fuel -burning parts, home appliances, and home appliances.
For example: The difference between 430/2B stainless steel and 430/AB stainless steel lies in 430/2B is a fog -surface stainless steel, 430/ba is a bright stainless steel, 430/ba corrosion resistance and 430/2B are almost the same, mainly surface gloss The difference is caused by different processing process. Stainless Steel 430/BA has a large number of spot stocks to choose from buying Gangle spot mall.
So what are the specific processing processes of 430 stainless steel? Let's describe it briefly below:
1D -surface has discontinuous granular, also known as mist surface. Processing process: hot rolling+annealing spray acid washing+cold rolling+antidium pickled.
2D — a slightly shiny silver white. Processing process: hot rolling+annealing spray acid washing+cold rolling+antidium pickled.
2B — is silver -white and better luster than 2D surface. Processing process: Hot rolling+annealing spraying acid washing+cold rolling+annealing pickling+quality rolling rolling.
BA -has a good surface gloss and has a high reflectivity, like the surface of the mirror. Machining process: Hot rolling+annealing spraying acid washing+cold rolling+annealing pickling+surface polishing+quality rolling rolling.
NO.3 -has a good luster and coarse surface. Processing process: Polish and rolled quality for 2D or 2B with 100 ~ 120 grinding materials (JISR6002).
NO.4 -has a good gloss and fine lines. Processing process: Polish and rolled the quality of 150 ~ 180 grinding materials (JISR6002) for 2D or 2B.
HL — is silver -gray and has a silk stripe. Machining process: Polish the grinding material of 2D or 2B products to polish the surface of the surface to make the surface continuously grind.
Mirro — mirror state. Processing process: grinding and polishing to the mirror effect on the grinding material with appropriate particle size with 2D or 2B products.
