Engine Valve Tech                                                    

1) Entire material valve (40Cr, 4Cr9Si2, 4Cr10Si2Mo)

2) Double metal friction welding (21-4N___40Cr, 4Cr9Si2, 4Cr10Si2Mo )

3) Small soldering ternimal pin (21-4N___4Cr10Si2Mo )

4) Small soldering alloy (21-4N___Nickle alloy )

5) Shaft chromium-plated (partially or entirely)

6) Surface nitrided treatment

 Characteristic                                                           

1). SUH-3(4Cr10Mo): for intake valves, good wearability, magnetism

2). SUH-35(21-4N): for exhaust valves, non-magnetism, make heat, spreak fast

3). TIP( one piece tip welding): to prevent wear, increase its hardness of valve top
