描述
SUS 443J1(JFE443CT) — The Smart Choice for High‑Performance, Eco‑Friendly Stainless Steel
- Outstanding Corrosion Resistance: With ~21% chromium, JFE443CT offers corrosion resistance equal to or better than SUS 304 — ideal for harsh environments like coastal or high-humidity areas.
- Resource-Efficient: Completely free of nickel and molybdenum, removing dependence on volatile alloy markets and ensuring stable cost.
- Low Thermal Distortion: About 40% lower coefficient of thermal expansion than SUS 304, minimizing deformation during welding or thermal cycling.
- Excellent Formability: Low work hardening, superior deep-drawing capability (LDR higher than SUS 304), ideal for complex stamping and deep-drawn parts
- Lightweight & Magnetic: Density ~7.74 g/cm³ (about 2.5% lighter than SUS 304) and magnetic — suitable for magnetic sorting and induction‑heating cookware (e.g., IH pots).
- Reliable Weldability: Supports TIG, MIG, MAG, and spot welding with maintained corrosion resistance at welded zones.
- Certified & Proven: JIS-certified (SUS443J1), with long-term field exposure data proving durability.
Ideal Applications
- Building & Architecture: Cladding, roofing, handrails, decorative piping, expansion joints
- Industrial Equipment: Ducts, control panels, clean-room housings, semiconductor / LCD machinery
- Appliances & Cookware: Induction cookers, rice cookers, sinks, range hoods, refrigerators
- Outdoor Structures: Especially suited for coastal areas and parts sensitive to heat-induced distortion
SUS 443J1 is a cost-efficient, highly corrosion-resistant, and formable ferritic stainless steel — a smart alternative to SUS 304 for demanding environments and budget-conscious projects.
