JFE443CT (SUS443J1)
Eco-friendly stainless steels with excellent corrosion resistance, totally free of nickel and molybdenum (SUS304 substitute)
Features of JFE443CT
-
1. Stable price
Stable price, since JFE443CT does not contain nickel or molybdenum, which expensive and subject to sharp price fluctuations
-
2. Excellent corrosion resistance
Corrosion resistance is as good or better than that of SUS304. Demonstrates superior performance to SUS304 in long-term exposure in coastal outdoor environments.
-
3. Excellent physical properties
JFE443CT does not thermally expand as much as SUS304 does, resulting in less thermal deformation due to heating during welding and use.
-
4. Wide variety of surface finishes
In addition to “glossy" and “hairline” finishes, it is also available in a "white" finish, very similar to the glossy finish of SUS304, and in a “tandem” finish for easy painting.
JFE443CT can be used for a wide range of applications!
Applications for “housing”
- Kitchens, cooking equipment (IH pots, kitchen sinks, microwave ovens, ventilation hoods, etc.)
- Mailboxes, trash collection bins, clothes drying poles & stands, rain gutter fittings, etc.
- Photovoltaic generation stands, battery housings
- Elevators
Thanks to its excellent drawability, JFE443CT can be designed with many different shapes.
For photovoltaic generation stands, which are constantly exposed to the heat of the sun, JFE443CT’s strong resistance to thermal deformation makes it more suitable than SUS304.
Applications for “public facilities” and “parks”
- Roofs
- Automatic doors
- Handrails
- Reflective plates for lighting
- Photovoltaic generation stands, battery housings
- Emergency cabinet
Thanks to its strong resistance to thermal deformation, as well as its corrosion resistance, JFE443CT can be reliably used for roofs that are constantly exposed to direct solar radiation.
Applications for “expressways,” ”roads” and “rivers”
- ExpresswaysSoundproofing walls, road sign boards, roadside cabinets
- RoadsCabinets for communications equipment
- RiversCabinets for measuring instruments
Since it boasts better corrosion resistance than SUS304, JFE443CT is well suited to use in coastal areas.
The tandem finish of JFE443CT is less expensive and easier to paint than the hairline finish of SUS304, resulting in excellent cost performance.
Applications of “factories” and “warehouses”
- OutdoorsRoofs, external walls, shutters, photovoltaic generator panel stands, and battery cabinet brackets
- Indoorfloors, internal walls, swing doors, ducts, cable racks, fire hydrant cabinets
JFE443CT is widely used in coastal areas, and other locations where corrosion resistance is required.
JFE443CT undergoes minimal deformation when it is seam welded and its finish is flat, so it can be kept clean when used for internal and external walls.
