SUS 430J1L is a ferritic stainless steel grade based on JIS standards, widely used in household appliances, kitchen equipment, automotive exhaust parts, and heat-resistant structural components. With improved corrosion resistance, good formability, and excellent oxidation resistance, 430J1L stainless steel is considered an upgraded version of the conventional SUS 430.
If you are looking for a cost-effective stainless steel solution with stable performance, SUS 430J1L is one of the most popular choices among Asian and global manufacturers.
What Is SUS 430J1L Stainless Steel?
SUS 430J1L is a ferritic stainless steel containing 16–20% chromium and ultra-low carbon. It maintains magnetic properties, high heat resistance, and improved corrosion resistance compared with standard SUS 430.
This grade is often used where:
Cost control is important
Higher chromium is required
Moderate corrosion resistance is needed
Oxidation resistance at elevated temperatures matters
As a longtime stainless steel supplier, Huaxiao Metal provides SUS 430J1L in coil, strip, sheet, plate, tube, rod, and customized shapes.
