Commercial
(Precipitation Strengthened steel)

CHSP45C

Adding hardening elements, such as Nb, Cr and V, to low carbon steel enhances its strength and yield point. It has excellent crack resistance and is used for structural purposes where strength is needed.

Seat, Rail levers, and Parking Brackets of automobiles

Drawing
(Soil Solution Strengthened Steel)

CHSP35R
CHSP40R
CHSP45R

This is high strength steel with soil solution hardening elements, such as phosphate(P). It is used in automobile panels for its increased strength.

Center floor and brackets, etc.

Deep Drawing
(Soil Solution Strengthened Steel)

CHSP35E
CHSP40E
CHSP45E

This is ultra-low carbon steel with special elements added. It has a high elongation rate and is used in deep draw parts of automobiles outer panels.

Outer panels of Doors and Fenders, ect.

Extra Deep Drawing
(Soil Solution Strengthened Steel)

CHSP35ES
CHSP40ES

As the ultra carbon steel added with some special elements, this product has superior high strength and elongation. It is possible to lighten an automobile by applying it to the parts for deep drawing.

Inner and Outer Materials of Roofs, Hood Member, etc.

Steel with Guaranteed YS
(Yield Strength)

CHSP260Y
CHSP340Y
CHSP380Y

This product has a very high yield strength compared to the exiting high strength steel types since it is manufactured with its ultra fine ferric structure by using some special chemical elements.
