S1 Alloy contains 17%~19% Cr and 1%~1.7% Ni.
It has good resistance to abrasion, corrosion and smash, widely used in all kinds of gasoline and diesel engines.
S2 Alloy contains 12%~14% Cr and 2%~2.5% Mo.
It has good resistance to abrasion, corrosion, smash and high temperature.
In addition to applying to gasoline and diesel engines, S2 is also suitable for Biofuel.
S3 Alloy contains 3.5%~4.2% Cr, 6%~7% Mo and 5~6%W.
In addition to good resistance to abrasion, S3 also has good endurance of high temperature.
S4 Nickel-based alloys has 27%~31% Cr, 14%~16% W and 50%~57% Ni.
Non-magnetic nickel-based alloys is suitable to apply to LPG engines.
