Stainless steel is the abbreviation of stainless and acid-resistant steel. The steel that is resistant to weak corrosive media such as air, steam and water or has stainless steel is called stainless steel; Corroded steel is called acid-resistant steel.
201, 202, etc.: Substitute manganese for nickel, which has poor corrosion resistance and is widely used as a cheap substitute for 300 series in China
300 Series: Chromium-Nickel Austenitic Stainless Steels
301: Good ductility, used for molded products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
302: The corrosion resistance is the same as that of 304, and the strength is better due to the relatively high carbon content.
303: It is easier to cut than 304 by adding a small amount of sulfur and phosphorus.
304: Universal model; i.e. 18/8 stainless steel. Products such as: corrosion-resistant containers, tableware, furniture, railings, medical equipment. The standard composition is 18 % chromium plus 8 % nickel. It is a stainless steel that is non-magnetic and cannot be changed by heat treatment. The GB grade is 06Cr19Ni10.
304 L: Same characteristics as 304, but with low carbon, it is more corrosion-resistant and easy to be heat-treated, but has poor mechanical properties. It is suitable for welding and products that are not easy to be heat-treated.
304 N: The same characteristics as 304, it is a nitrogen-containing stainless steel, nitrogen is added to improve the strength of the steel.
309: Compared with 304, it has better temperature resistance, and the temperature resistance is as high as 980ºC.
309 S: It has a lot of chromium and nickel, so it has good heat resistance and oxidation resistance. Products such as heat exchangers, boiler components, and jet engines.
310: Excellent high temperature oxidation resistance, the maximum operating temperature is 1200 ºC.
316: After 304, the second most widely used steel grade, mainly used in the food industry, watch accessories, pharmaceutical industry and surgical equipment, adding molybdenum to obtain a special structure that is resistant to corrosion. Because of its better resistance to chloride corrosion than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery units. Grade 18/10 stainless steels generally also meet this application level.
316 L: Low carbon, so it is more resistant to corrosion and easy to heat treatment. Products such as chemical processing equipment, nuclear power generators, and refrigerant storage tanks.
321: Similar to 304, except that the risk of corrosion of material welds is reduced due to the addition of titanium.
347: Add stabilizing element niobium, suitable for welding aircraft parts and chemical equipment.
400 series: ferritic and martensitic stainless steel, manganese-free, to some extent replace 304 stainless steel
408: Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409: The cheapest model (UK and US), usually used as a car exhaust pipe, is a ferritic stainless steel (chromium steel).
410: Martensitic (high-strength chromium steel), with good wear resistance and poor corrosion resistance.
416: The addition of sulfur improves the processing properties of the material.
420: "Cutting-grade" martensitic steel, the earliest stainless steel similar to Brinell's high-chromium steel. Also used in surgical knives, can do very bright.
430: Ferritic stainless steel, decorative, eg for car accessories. Good formability, but poor temperature and corrosion resistance.
440: High-strength cutting tool steel with slightly higher carbon content. After proper heat treatment, higher yield strength can be obtained, and the hardness can reach 58HRC, which is one of the hardest stainless steels. The most common application example is "razor blades". There are three commonly used models: 440A, 440B, 440C, and 440F (easy to process).
500 Series: Heat-resistant chromium alloy steel.
600 Series: Martensitic precipitation hardening stainless steel.
Due to the difference in chemical composition of the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel is generally stainless. The term "stainless steel" does not simply refer to one type of stainless steel, but to more than one hundred industrial stainless steels, each developed to perform well in its specific field of application.
BA/2B/NO.1/NO.3/NO.4/8K/HL/2D/1D
Original surface: NO.1 The surface subjected to heat treatment and pickling treatment after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industry equipment, etc., the thickness is thicker from 2.0MM-8.0MM.

Due to the smooth surface, it is easy to regrind, making the surface brighter and widely used, such as tableware, building materials, etc. With surface treatments that improve mechanical properties, it is suitable for almost all applications.
Coarse sand: NO.3 Products ground with No. 100-120 grinding belts. Has better gloss, with discontinuous coarse lines. It is used for building interior and exterior decoration materials, electrical products and kitchen equipment, etc.
Fine sand: NO.4 The product is ground with a grinding belt with a particle size of 150-180. Has better gloss, with discontinuous coarse lines, and the stripes are thinner than NO.3. For baths, decorative materials inside and outside buildings, electrical products, kitchen equipment and food equipment, etc.
#320 Product ground with No. 320 belt. It has better gloss, with discontinuous rough lines, and the stripes are thinner than NO.4. It is used for baths, interior and exterior decoration materials of buildings, electrical products, kitchen equipment and food equipment, etc.
Hairline surface HAIRLINE: HLNO.4 is a product with a grinding pattern (subdivided 150-320) by continuous grinding with a polishing abrasive belt of appropriate particle size. Mainly used for architectural decoration, elevators, doors and panels of buildings, etc.
Bright surface: BA is cold rolled, bright annealed, and flattened. Excellent surface gloss and high reflectivity. like a mirror surface. Used in home appliances, mirrors, kitchen equipment, decorative materials, etc.200 Series: Chromium-Manganese-Nickel

1. Weldability
Different product uses have different requirements for welding performance. A class of tableware generally does not require welding performance, and even includes some pot enterprises. However, most products require good welding performance of raw materials, such as second-class tableware, thermos cups, steel pipes, water heaters, water dispensers, etc.
2. Corrosion resistance
Most stainless steel products require good corrosion resistance, such as Class I and II tableware, kitchen utensils, water heaters, water dispensers, etc. Some foreign merchants also do corrosion resistance tests on the products: use NACL aqueous solution to heat it to boiling, and pour it after a period of time. Remove the solution, wash and dry, and weigh the weight loss to determine the degree of corrosion (Note: When the product is polished, the Fe content in the abrasive cloth or sandpaper will cause rust spots on the surface during the test)
3. Polishing performance
In today's society, stainless steel products are generally polished during production, and only a few products such as water heaters and water dispenser liner do not need polishing. Therefore, this requires that the polishing performance of the raw material is very good. The main factors that affect the polishing performance are as follows:
(1)Surface defects of raw materials. Such as scratches, pitting, pickling, etc.
(2)The problem of raw materials. If the hardness is too low, it will not be easy to polish when polishing (the BQ property is not good), and if the hardness is too low, the orange peel phenomenon is easy to appear on the surface during deep drawing, thus affecting the BQ property. BQ properties with high hardness are relatively good.
(3)For the deep-drawn product, small black spots and RIDGING will appear on the surface of the area with a large amount of deformation, thus affecting the BQ performance.
4. Heat resistance
Heat resistance means that stainless steel can still maintain its excellent physical and mechanical properties at high temperatures.
Influence of carbon: Carbon is an element that strongly forms and stabilizes austenite and expands the austenite region in austenitic stainless steels. The ability of carbon to form austenite is about 30 times that of nickel, and carbon is an interstitial element that can significantly increase the strength of austenitic stainless steel through solid solution strengthening. Carbon can also improve the stress corrosion resistance of austenitic stainless steel in highly concentrated chloride (such as 42% MgCl2 boiling solution).
