Chinese grade: 1Cr18Ni9 (new grade: 12Cr18Ni9) corresponding to American grade (ASTM A276-96) : 302 corresponding to DIN grade: 1.4307
Standard: GB/T 1220-1992
● Characteristics and scope of application:
The cold processing has high strength, but the elongation is slightly worse than 1Cr17Ni7. Decorative components for construction. Improve machinability and burn resistance. Most suitable for automatic lathes. Bolts and nuts. No corrosion, pitting, rust or wear. Stainless steel is also one of the strongest materials in building metal materials
