KST(Korea Surface Treatment) Plant is a young enterprise that manufactures best quality valves specialized in the on/offshore Oil & Gas and petrochemical sector as well as Shipbuilding Industry. KST Plant, starting as an investment company with KITECH(Korea Institute of Industrial Technology), developed the unrivaled surface treatment technology such as KCC (KST Chromized Carbide), KNN (KST Nano Nitriding) and etc. which greatly improve metal hardness and resistance to corrosion and chemical as well as abrasion and friction. We applied our specialized surface treatment technology on valves, chute liners, impellers, bearings, semiconductor and etc of the power plant, on/offshore and petrochemical sector in oil & gas included shipbuilding. We, also, applied our technology on the balls and seats of metal seated valves included the precise machining technology (Tolerance 0.005mm). For valves, we have guaranteed “0” leakage as well as the above mentioned strong points, improved hardness and resistance to corrosion and chemical. KST Plant is committed to keep clients at competitive edge by consistently providing and servicing superior quality and competitive pricing. We will emerge as a large manufacturer of specialized valves in a future 10 years.
