With the addition of CU, it has good molding ability, particularly deep drawing ability and aging crack ability. The product can be molded into a complex shape, and its corrosiveness is the same as that of 304 steel. |
Vacuum bottles, sink pots for the kitchen, door knobs, and products that require spinning processing. | HR,CR |
| 304N1 18Cr-8Ni-N |
Lowering the content of S, Mn but adding N to 304 steel will allow it to prevent a decrease in ductility, but the strength and thickness of the material will be reduced. |
Structural materials, streetlight, water tanks, water pipes | HR,CR,P |
| 304LN 18Cr-8Ni-N |
Compared to 304 L, austenite is a type of steel for structures that exhibits improved strength and pressure resistant corrosiveness with the addition of N. |
For structures, for hot water supply, and for chemical delivery ships. | P |
| 305 18Cr-11Ni -Si,Mn |
A stainless-steel type containing a large amount of NI, it is non-magnetic, making it ideal for use in electronic parts, and has a good cold-rolled molding feature that makes it appropriate for in-depth processing use. |
Western tableware, electronic parts. | HR |
| 316 18Cr-12Ni -2.5Mo |
With the addition of Mo, it has superior corrosion resistance, pitting resistance, and strength against high temperature. It is thus superior for use, processing, and hardening under severe conditions (contains no magnetism). |
Seawater facilities, chemicals, paper manufacturing, dyes, nitric acid, fertilizer -manufacturing facilities, photos, food industry, seashore area facilities, ropes, CD bars, bolts, nuts | HR,CR,P |
| 306L 18Cr-12Ni -2.5Mo-LowC |
A low-C-content 316 steel that possesses the latter’s characteristics, it can withstand pressure corrosiveness and is thus superior. |
Products that must be able to withstand pressure corrosiveness (e.g., mesh) | HR,CR,P |
| 321 18Cr-9Ni-Ti |
As Ti is added to 304 steel to allow it to withstand pressure corrosiveness, it is suitable for use under temperature conditions of between 430 and 900°C. |
Exhaust pipes for aircrafts, boiler covers, heat exchangers | HR,CR,P |
| 409 11.3Cr-0.17 Ti-저C,N |
Has good high-temperature corrosion resistance and high-temperature strength, with the addition of Ti |
Not used for post-heating treatment after welding, such as for vehicle exhaust pipes, heat exchangers and containers, etc. | HR,CR |
FERRITE
