Epoch-making surface modification technology
 

Multinite process is the gas sulphonitriding and iron sulfide and iron nitride are made to form in the surface of all the steel material from cast iron to stainless steel.
It is surface modification, which has the excellent effect of wear, low friction and attrition resistance in lubricous or non-lubricous condition.
