Stainless Steel Surface Treatments
1D—The surface has discontinuous particles, which is also called matte. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D—Slightly shiny silver-white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B—Silver white and better gloss and flatness than 2D surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
BA—The surface gloss is excellent and has a high reflectivity, just like the mirror surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenched and tempered rolling.
No.3—has better gloss and rough surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 100 ~ 120 abrasive materials.
No.4—has better gloss and fine lines on the surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 150 ~ 180 abrasive materials.
HL—Silver gray with hair streaks. Processing technology: Polish the 2D product or 2B product with a suitable size of abrasive material to make the surface appear continuous grain.
MIRROR Machining —is in a mirror state. Processing technology: 2D or 2B products are ground and polished to a mirror effect with a suitable abrasive material.
| Surface Finish | Definition | Application |
| 2B | Those finished, after cold rolling, by heat treatment, pickling or other equivalent treatment and lastly by cold rolling to given appropriate luster. | Medical equipment, Food industry, Construction material, Kitchen utensils. |
| BA | Those processed with bright heat treatment after cold rolling. | Kitchen utensils, Electric equipment, Building construction. |
| NO.3 | Those finished by polishing with No.100 to No.120 abrasives specified in JIS R6001. | Kitchen utensils, Building construction. |
| NO.4 | Those finished by polishing with No.150 to No.180 abrasives specified in JIS R6001. | Kitchen utensils, Building construction, Medical equipment. |
| HL | Those finished polishing so as to give continuous polishing streaks by using abrasive of suitable grain size. | Building construction |
| NO.1 | The surface finished by heat treatment and pickling or processes corresponding there to after hot rolling. | Chemical tank, pipe. |

Tips:
haracteristics and use of 200,300,400,500,600 series stainless steel
consider valuable and collect appropriately! The 200 to 600 Series stainless steel features are fully resolved
Today, stainless steel prices affected by the trade war once down, the market trading flat. Tomorrow is the weekend, xiaobian to bring you 200 series to 600 series of stainless steel use and the nature of the introduction, I hope to help you.
201-With a certain acid resistance, alkali resistance, high density, polishing without bubbles, no pinhole and other characteristics, mainly used for decorative pipe, industrial pipe, some shallow tensile products.
202- -widely used in building decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places.
204-Better toughness than 201, less impurities than 201, corrosion resistance, stamping performance is far better than 201,204 is generally used in a complex environment, but the price is also higher than 201.
301- -Good ductility, used for molding products. It can also be hardened at machine speed. Good welding. The abrasion resistance and fatigue strength are better than the 304 stainless steel.
302- -Corrosion resistance is similar to 304, which is better due to the relatively high carbon content.
303-By cutting by adding a small amount of sulfur and phosphorus.
304- -namely 18 / 8 stainless steel. The GB card number is 0Cr18Ni9.
309- -Has better temperature resistance than 304.
316- -After 304, the second most widely used steel type, mainly used in the food industry and surgical equipment, is used by adding molybdenum elements to obtain a special corrosion-resistant structure. It is also used as marine steel because it has better chloride corrosion resistance than 304. SS316 is commonly used for nuclear fuel recovery units. Grade 18 / 10 stainless steel usually also meets this application level.
321-Performance similar except that titanium reduces the risk of weld corrosion 304.
408- -Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409- -The cheapest model (British and American), usually used as a car exhaust pipe, is a ferrite stainless steel (chromium steel).
410-Martensite (high strength chromium steel), good wear resistance, poor corrosion resistance.
416- -Adding sulfur improves the processing performance of the material.
420- "Blade grade" martensitic steel, similar to cloth high chromium steel, the earliest stainless steel. Also used in surgical knives, which can be done very bright.
430-Ferric body stainless steel, for decoration, for example for automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.
440-High strength blade steel, slightly higher carbon content, after appropriate heat treatment can obtain high yield strength, hardness can reach 58HRC, belongs to the hardest stainless steel. The most common example of the application is the "razor blade".
There are three common models: 440A, 440B, 440C, and another 440F (easy to process type).
500 Series-Heat-resistant chromium alloy steel.
600 Series-Martensitic precipitation-hardened stainless steel.
630- -The most commonly used precipitation-hardened stainless steel model, usually also called 17-4; 17%Cr, 4%N
