300 series stainless steel contains nickel and chrome. Nickel costs account for more than 65% of the total cost. The advantage is that anti rust effect is very good. The disadvantage is that price is high.
301, 302, 303, 304, 304L, 309, 316,316L and 321 are Chromium-Nickel stainless steels with high strength developed by cold working. This series is non-magnetic, not hardened by heat treatment, and has excellent formability. The most widely used austenite steel is the 304, also known as 18/8 for its composition of 18% chromium and 8% nickel. 304 may be referred to as A2 stainless. The second most common austenite steel is the 316 grade, also referred to as A4 stainless and called marine grade stainless, used primarily for its increased resistance to corrosion. On account of adding molybdenum, the corrosion resistance is strengthening. It is used in cookware, chemical equipment and architectural applications.

301
1Cr17Ni7
 Compared with the 304 steel, content of Cr, Ni is less. When cold working, tensile strength and hardness increase. Nonmagnetic, but after cold working, it has magnetic.
Train, aircraft, conveyor belt, vehicles, bolts, nuts, springs, screen mesh
304
0Cr18Ni9
As a kind of widely used steel, 304 has good corrosion resistance, good heat resistance, low temperature strength and mechanical properties;
Hot work ability is good, such as punching and bending. No heat treatment hardening (non-magnetic, using temperature from minus 196 degrees to 800 degrees Celsius)
Medical instruments, building materials, chemical, marine parts, auto parts, food industry, household, agriculture
304L
00Cr19Ni10
As low carbon steel of 304 stainless steel, under the general condition, its corrosion resistance is similar to 304 steel, but after welding or eliminate stress, the corrosion resistance of grain boundary is good;
Under the condition of without heat treatment, it can also keep a good corrosion resistance; using temperature is from minus 196 degrees to 800 degrees Celsius.
open machine of requiring high chemical industry, coal, oil field ; building materials heat-resistant parts ;Â have difficulty in heat treatment of parts
309
0Cr23Ni13
Compared with 304,the content of Ni, Cr is more; has better resistance to the temperature
Boilers, energy (nuclear power, thermal power, fuel cell), industrial furnaces, incinerator, heating furnace, chemical industry, petrochemical industry
316L
00Cr17Ni14Mo2
As the low Carbon and containing Molybdenum stainless steel, and in addition to the same feature of 316 steel, the grain boundary corrosion resistance is excellent.
In corrosion medium containing chlorine ion, it has higher corrosion resistance than 304, 304 L.
For desalination and water industry
321
0Cr18Ni10Ti
Ti is added in the 304 steel to prevent grain boundary corroded, suitably use from 430 degrees to 430 degrees.
Aircraft, exhaust pipe, boiler steam drum
