Commercial Cold Rolled Steel
| Type |
Standard
Model No. |
Features |
Applications |
| Type 1 |
KS-SCP1-S |
It is used for areas which are necessary for bending, molding, simple machining and welding. |
Refrigerator, Door, Drum, Furniture, etc. |
| Type 2 |
KS-SCP2-S |
It is for machining, which is used for areas where are required for formability much than CSP 1. |
Oil Pan of automobile, etc. |
| Type 3 |
KS-SCP3-S |
It is for deep machining, which is used for areas where are required for formability much than CSP 2 |
Automobile Roof, Fender, Hood, etc. |
| KS-SCP3N-S |
It is for deep machining and is a non-aging stiffening steel plate that the quality of the material does not change even after passing a certain period. |
| CSP 3E |
It is for extra deep machining(drawing), which is applied to automobile parts(components), etc. that need formability much than CSP 3N. |
Automobile Quarter, Spring House, etc. |
Cold Rolled Steel for Porcelain Enamel
| Type |
Standard
Model No. |
Features |
Applications |
| Porcelain Enamel |
KS-SPP |
It has excellent formability because it is manufactured by high titanium, ultra low carbon steel and boron-added low carbon steel, has no an enamel defect like fish scale, pin hole, etc., and thermal strain does not occur even it is burnt at high temperature(800-850˚C). |
Washing machine, dehydrator, enamel bathtub, enamel tableware, pan, building exterior materials, etc. |
High Strength Cold Rolled Steel
| Type |
Standard
Model No. |
Features |
Applications |
| General Use |
CHSP 45C
CHSP 60C |
It has excellent impact resistance due to high yield point and strength because it is manufactured by adding precipitation hardening elements (Nb, Cr, V) to low carbon steel and precipitation hardening elements prevent such precipitates in the steel plate from fine dispersion and movement of dislocation. Applicable to structures which are necessary for high strength. |
Automobile Seat, Rail Lever, Parking Brake, etc. |
| Machining |
CHSP 35R
CHSP 40R
CHSP 45R |
It is solid solution hardening steel, which has excellent formability and is applicable to components or parts for the purpose of improving strength like car panel, etc. |
Center Floor, Bracket, etc. |
| Deep Machining |
CHSP 35E
CHSP 40E
CHSP 45E |
It is steel adding a special element to ultra-low C and N steel and especially has outstanding r and elongation. Applicable to deep machining for outer panel of automobiles. |
General outer plate like Fender, Hood, etc. |
| Low Yield Ratio Steel |
CHSP 35EB |
It is soft steel when molding processing, but its yield strength becomes high when plating baking after machining. With improved dent-proof and impact resistance. Same formability as CHSP35. |
| Bake Hardening Steel |
CHSP 60DP
CHSP 80TR
CHSP 100DP |
It forms 3-phase (ferrite + martensite + residual ustenite) and 2-phase (ferrite + martensite) composition at room temperature. For its yield ratio (YP/TS) is relatively lower than solid solution hardening steel, it is used for stiffening materials with high strength which needs machining. |
Door, Bumper Stiffener |
