Main uses of precision STS products
According to the recent trends of weight reduction and miniaturization, the market requires thinner and narrower stainless steel materials. POSCO MOBILITY SOLUTION has the state-of-the-art technologies to meet customer needs and market trends.
POSCO MOBILITY SOLUTION’s stainless steel products possess precise mechanical properties and perfectly managed flatness.
The latest development in the head gasket technology is multilayer steel (MLS) design, which has three to seven layers of thin stainless spring steel. MLS head gaskets provide the ultimate in torque retention and give extra strength to support current lightweight engine design.

Brake pad spring
The temper rolled stainless spring steel installed in an automotive brake system transfers pressure from the pedal to brake pads. Because of its complicated design, precise thickness and flatness tolerances are required to optimize bending and formability.
|Size||301 [ AR : 0.4~0.5mm ]|
|Application||Automotive brake system|
Bellows are installed in the automotive exhaust system to reduce the noise level and dampen engine vibration. Exhaust bellows by precision stainless steel serve to absorb thermal and vibrational stresses at high temperature, and compensate for misalignment in the exhaust assembly.
|Size||321/316Ti/309Si [ 2B,BA : 0.15~0.3mm ]|
|Application||Automotive exhaust system|
Stainless steel molding materials add visual allure to an automotive exterior. Depending on a vehicle’s design, its surface can be changed in a number of ways to create unique values.
|Size||430J1L/436L [ BA, Dull, Color: 0.4t - 0.5mm ]|
STS used in USIM sockets, power shells and USB connection terminals are subject to precision high-speed press blanking. So precise thickness and flatness are the most important factors when raw materials are selected.
|Size||304/301 [ AR 0.1mm~0.3mm ]|
|Application||Mobile, Notebook, TV, etc.|
This technology allows production of product parts which cannot be easily produced by press processing or other conventional methods. It involves processing with chemicals, and is used in small-quantity batch production.
|Size||304 [ AR,BA : 0.1~0.3mm ]|
|Application||Print components, Name plates, Juicer filter etc|
Along with the growing interest in “Warm Edge” technology which improves heat preservation of buildings, the demand for stainless steel window spacers is constantly increasing with better thermal insulation, noise-proof and condensation-proof.
|Size||304/430 [ BA : 0.1mm ]|
|Application||Window Spacer Frame|
Fuel cell separation membrane
POSCO MOBILITY SOLUTION produces and supplies non-coated, highly corrosion-resistant, and highly conductive STS, which will be used in battery technology of hydrogen-powered and electric vehicles.
