Commercial Quality

Adding hardening elements, Nb, Cr, and V to low carbon steel gives this type of steel its high strength and yield strength. It has excellent crack resistance and is used for structural purposes where strength is needed.

 
Seats, rail levers and parking brake of automobiles
SPFC440, SPFC490, SPFC590
Drawing Quality
This is high strength steel made by adding such soild solution hardening elements as P and is used in parts like automobile panels to enhance strength.
   
Center floors and brackets of automobiles
SPFC390, SPFC440
Deep Drawing Quality
This steel is made by adding elements to ultra low carbon steel. Its elongation is excellent and is used in deep drawing parts for outer panels of automobiles.
 
Outer panels such as fenders and hoods of automobiles
SPFC340, SPFC370
Dual Phase
By baking after press forming, the yield strength of the steel is heightened and its dent-resistant property is improved. The formability is the same as CRHS 35.
 
Outer panels such as fenders and hoods of automobiles
SPFC340H
Bake Hardening
In constant temperature, it forms a ferrite matrix grain and has a lower yield strength radio than that of high strength steel. It is used as a strength enhancing material.
   
Doors and bumpers of automobiles
SPFC490Y, SPFC590Y, SPFC780Y, SPFC980Y

Company introduction

Dear Prospective Buyers: Thank you very much for your interest in HYSCO, an enterprise specializing in the manufacture of automotive steel sheet. Humanity has passed through the Stone Age and the Bronze Age, and we are now living in a civilization reliant on the forging and shaping of metal. Most of people tend to think that the steel industry is distantly removed from their everyday lives. But if you look around closely, you can easily see how deeply steel and iron are imbedded in almost every facet of our daily routine. Thus, archeologists have named this historical period the "Iron Age." HYSCO is a company that produces automotive steel sheet and various steel pipes. Of our numerous steel-based products and equipment, we largely focus corporate efforts on these two particular areas. HYSCO was first established as Kyung-il Industrial Co., Ltd. in 1975 and later renamed as Hyundai Pipe Co., Ltd in 1980. In 2001, on the cusp of the 21st century, we renamed the firm once again as HYSCO. In response to rapid changes in the steel industry and as befitting our position as a global leader, we have concentrated efforts on the uplift of profitability while still making a rich contribution to society. The cold rolling mill started commercial operation in 1999, and is a representative part of such change and progress. We would like you to watch our dynamic progress. With your constant interest, HYSCO promises to become the world? best manufacturer of automotive steel sheet and high value-added steel pipes. Thank you very much.
