Brand name: SUS 304CUN

basic information

**Features** ■ High Strength - Tensile strength of 900–1,000 N/mm² - Achieved mass production level of A2-90/100, which is outside the mechanical property standards for austenitic materials JIS B1054 - Comparable high strength to SUH 660 and SCM 435 ■ Untreated - Strength increase possible through cold forging only (A2-90) - No concerns about market complaints due to heat treatment processes (aging cracks, delayed fractures) ■ High Heat Resistance - No carbon precipitation occurs at 500–700℃ - High temperature range for grain boundary corrosion ■ High Corrosion Resistance - Stress corrosion cracking resistance comparable to SUS 316 ■ Non-Magnetic - Permeability (μ) of 1.01–1.03 ■ Weight Reduction - Overall weight reduction by changing from A2-50 to A2-90 - Possible 70% weight reduction by reducing the nominal diameter by three sizes (changing from A2-50 to A2-100 with a yield strength of 900 MPa allows for changing from M20 to M12) ■ Convenience - Domestic product with high adaptability and flexibility
