Anti-Corrosion:
     It has the character of anti-rust and anti-corrosion.As the quanlity of Cr is increased,anti-nitric acid and other oxidizability acid's corrosion and high-temperature anti-oxidizability, acidiablity will be increased.Alonged with Ni be increased,anti chlorid corrosion character and anti reducibility acid's character will be increased.When the Cr will be reduced or add stable element,the steel's anti crystal structure corrosion will be improved.As increased the Mo,steel's anti reducibility acid and anti pitting corrosion and gap corrosion character will be increased.The steel contains Cu,especially Mo and Cu compound,the steel's anti-nitric acid character has aparently improved.When it contains Si 4%,it can anti fuming nitric acid corrosion.When low down some impurities in the steel,such as C,Si,P,Ti.It can be used as nitric,carbamide class stainless steel.

Mechanics and Physical Character:
     It has intensity-toughness-moldness good cooperation.It has good toughness in the low temperature environment,it can be used as low temperature steel.Along with C in the steel is reduced,steel's strongness will be downed a little. ( generally low carbon steel is lower than high carbon for 29.4~~49Mpa). Along with distortion measurement which in the cold states increased, steel's intensity and elasticity would be improved. When steel contains N, steel' s intensity Because of Mn and N' s consolidation, Cr-Mn Austenite Stainless Steel's intensity is 3% higher than Cr-Ni Austenite Steel, and moldness & toughness are still good. This kind of steel is non-magnetism, so it can be used as non-magnetic steel.

Anti-corrosion:
    The Martensite Nickel Chrome Stainless Steel has anti-rust,anti weak-medium corrosion. Along with Cr is increased and add Mo, its anti-corrosion is increased. Along with C is increased, its anti-corrosion is low-down.And when its hardness increase, its anti-sulfureted hydrogen and corrosion. The Martensite Nickel Chrome Stainless Steel has anti-rust, when it contains Cr17%, its anti corrosion will be same or a little lower than 18-8.

Mechanics and Physicaly Character:
    The Martensite Nickel Chrome Stainless Steel along with C increased, steel's intensity & hardness is increased, it can up to RC60 and above. Steel's anti-milling,but its toughness is bad.When it contains Mo&V,steel's intensity would be increased.When it contains fewer Ni,steel's intensity&toughness has good cooperation.This kind of steel has brittleness changeable temperature differences.It has magnetism,low density and good anti-shake character,its elastic measurement is a little bit lower than carbon steel.The Martensite Nickel Chrome Stainless Steel has high intensity(δs no more than 9800Mpa) and high hardness(RC no more than 36),has higher intensity/weight ratio.

Meterial In the Stainless Steel Bearings:
    SUS304,SUS316,SUS316L:the Austenite stainless steel bearing's inner&outer ring, ball, cage, rivet, pillow block, terminal strand, anti-dirt shield,seal framework. The Martensite Stainless Steel bearing's cage, rivet, pillow block,terminal strand,anti-dirt shield and seal framework.
    SUS440C,SUS440B: The Martensite Stainless Steel bearing's inner&outer ring,ball.
