 What Is Stainless Steel ?

In metallurgy, stainless steel also known as inox steel or inox, is a steel alloy, with highest percentage contents of iron, chromium, and nickel, with a minimum of 10.5% chromium content by mass and a maximum of 1.2% carbon by mass.Stainless steels are most notable for their corrosion resistance, which increases with increasing chromium content. Additions of molybdenum increase corrosion resistance in reducing acids and against pitting attack in chloride solutions. Thus, there are numerous grades of stainless steel with varying chromium and molybdenum contents to suit the environment the alloy must endure. Stainless steel's resistance to corrosion and staining, low maintenance, and familiar luster make it an ideal material for many applications where both the strength of steel and corrosion resistance are required.Stainless steels are rolled into sheets, plates, bars, wire, and tubing to be used in: cookware, cutlery, surgical instruments, major appliances; construction material in large buildings; industrial equipment (for example, in paper mills, chemical plants, water treatment); and storage tanks and tankers for chemicals and food products (for example, chemical tankers and road tankers). Stainless steel's corrosion resistance, the ease with which it can be steam cleaned and sterilized, and no need for surface coatings has also influenced its use in commercial kitchens and food processing plants.

Stainless Steel Grade

200 series: chrome-nickel-manganese austenitic stainless steel.
300 Series: Chrome-Nick Austenitic Stainless Steel.

Grade 301: Good ductility for molded products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel, such as spring, steel structure, wheel cover.

Grade 302: Corrosion resistance is the same as 304, because the carbon content is relatively high and the strength is better.

Grade 303: It is easier to cut than 304 by adding a small amount of sulfur and phosphorus.

Grade 304: Universal model; mainly available in 18 (chrome) / 8 (nickel) and 18 (chrome) / 10 (nickel) stainless steel. Products such as: corrosion resistant containers, tableware, furniture, railings, medical equipment. The standard ingredient is 18% chromium plus 8% nickel. It is non-magnetic. When the content of impurities is high, it will occasionally exhibit weak magnetic properties after processing. This weak magnetic property can only be eliminated by heat treatment. It is a stainless steel that cannot change its metallurgical structure by heat treatment.

Grade 304 L: Same characteristics as 304, but it is more resistant to corrosion and heat treatment due to low carbon, but it is mechanically poor for welding and heat-resistant products.

Grade 304 N: Same characteristics as 304. It is a nitrogen-containing stainless steel. Nitrogen is added to increase the strength of the steel.

Grade309: Better temperature resistance than 304.

Grade 309 S: With a large amount of chromium and nickel, it has good heat resistance and oxidation resistance, such as heat exchangers, boiler components and injection engines.

Grade 310 S: Contains the most amount of chromium and nickel, so it is the best heat exchanger for heat and oxidation resistance, boiler components and motor equipment.

Grade 316: Following 304, the second most widely used steel grade is used primarily in the food industry and surgical equipment, adding molybdenum to give it a special structure that resists corrosion. It is also used as "ship steel" because it has better resistance to chloride corrosion than 304. SS316 is commonly used in nuclear fuel recovery units. 18/10 grade stainless steel also generally meets this application level. It is especially used in chemical, seaside and other corrosive environments, ship assembly and building materials.

Grade 316 L: It is more resistant to corrosion and heat treatment due to low carbon. Products such as chemical processing equipment, nuclear power generators and refrigerant storage tanks.

Grade 321: In addition to the risk of material weld corrosion due to the addition of titanium, the performance is similar to 304, suitable for welding brewing equipment, steam pipes, and aerospace parts.

Grade 347: Adds a stabilizer element for welding aerospace parts and chemical equipment.

400 series: ferritic and martensitic stainless steel

Grade 408: good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.

Grade 409: In addition to the addition of titanium, it is commonly used as an exhaust pipe for automobiles. It is a ferritic stainless steel (chrome steel), suitable for welding, and has low cost for automobile exhaust pipes and petroleum equipment.

Grade 410: Martensite (high-strength chrome steel), good wear resistance, poor corrosion resistance, suitable for pumps. Its chemical composition contains 13% chromium, 0.15% or less of carbon and a small amount of other elemental alloys. It is magnetic and can be hardened by heat treatment. General uses include bearings, medical equipment and tools.

Grade 416: The addition of sulfur improves the processing properties of the material.

Grade 420: Contains higher carbon, hardness, higher strength, blade grade martensitic stainless steel, this earliest stainless steel, can be very bright, suitable for knives, springs, surgical instruments, razor cutting heads, valves.

Grade 430: Ferritic stainless steel, decorative, magnetic, for example for automotive accessories. Good formability, but poor temperature resistance and corrosion resistance, suitable for fasteners, tableware, furniture. Its standard chemical composition is 16-18% chromium with low carbon content. This type of stainless steel is magnetic.

Grade 434: Containing molybdenum, it has better corrosion resistance than 430. It is suitable for tableware, wipers and car decoration.

Grade 440: High-strength cutting tool steel with slightly higher carbon content. After proper heat treatment, it can obtain higher yield strength and hardness of 58HRC, which is among the hardest stainless steel. The most common application example is the "razor blade." There are three commonly used models: 440A, 440B, 440C, and 440F (easy processing type).

500 series: heat-resistant chrome alloy steel

600 series: martensitic precipitation hardening stainless steel
Grade 630: The most commonly used precipitation hardened stainless steel model, also commonly referred to as 17-4; 17% Cr, 4% Ni.
