1. Greeting

Dear Sir/Madam,

Hello. I am Seongtae Kim; a President of KST Plant Co. Ltd. in Gyeongnam, Korea.

Our company “KST Plant Co. Ltd” was established as a manufacturer of thermochemical products in

Dec., 2007.

Even though we provided customers with white machineries only for trains & Power Plants at the

beginning, our business area.

Now includes almost metal seated ball Valves for ships, power plants and so on.

In detail, our products are as follows.

○ For Offshore & Industrial Plants

● Metal Seated Ball Valve with Cr-C Surface Treatment

- Valve Inspection and Testing : API 598

- ANSI/FCI 70-2 Valve Leakge Classifications : Coveraged by CLASS Ⅵ

● Plazma-Nitriding Treatment Products for Various Industrial Plants

We welcome your any specific requirements.

And we are in a position to supply you with best quality goods at

competitive prices because we have the scrap company and wide supplying networks.

We expect to start good business with you in the near future.

Thanks so much.

Your very truly,

President / Seongtae Kim

Cr-C Surface Treatment

7

1.

Cr-C Surface Treatment is a thermochemical surface treatment, in which Cr-C atoms are diffused in the surface of work piece to form Cr-C Atoms with the base metal(Stainless Steel,Carbon Steel). Cr-C Surface Treatment steels are shown the high hardness and good wear, erosion and corrosion resistance. High hardness (1,600 – 2,000 Hv) High resistance to temperature (1200 ℉) Increases resistance to acids (HCl, H2SO4) Low friction coefficient (≤ 0.5) Can be polished to a high finish Diffusion layers are controllable

1.

Nano Plazma Nitriding is a thermochemical surface treatment, in which Nitrogen atoms are diffused in the surface of work piece to form nitrides(FeN, FexN) with the base metal(Stainless Steel). Nitrided steels are also shown the ultra-high hardness and wear, erosion and corrosion resistance

High hardness (1000 – 1300 Hv) Increases resistance to acids (HCl, H2SO4) Low friction coefficient (≤ 0.6) Can be polished to a high finish Diffusion layers are controllable
