Characteristics and example use

Classification Characteristics and example use
13Cr SUS1A-1 SUS1A-1 has the least amount of carbon among 13 chrome steels. As a result, among 13 chrome steels,SUS1A-1, has superior corrosion resistance with cold rolling and welding ability. AUS-1, SUS2A-S are increased carbon contents,improved heat treatment hardness and wear resistance. Use is medical equipment and others.
AUS-1
SUS2A-S
SUS3N-F Add sulfur to SUS420J2, improved machinebility. Use is gauges.
SUS420J2 JIS steel type,uses are popular knives,gauges.
AUS-6M AUS-6M,AUS-8 and AUS-10 are increased more carbon contents,added vanadium and molybdenum,improved more hardness,wear resistance,annealing resistance. Uses are high-quality knife,scissors,pocket knife,medical equipment, food machine,mechanical parts and more.
AUS-8
AUS-10
17Cr SUS440A These steels have corrosion-resistance and wear resistance at the same time. Improve wear resistance 1.SUS440A 2.ACUTO440 3.SUS440C(improving wear resistance) Uses are high-quality knife,hairdressing or cosmetic scissors,medical equipment, gauges,food machine,mechanical parts,automobile parts and more.
