Over 50 Stainless Steel Alloys Manufactured

Stainless steel is an alloy steel containing at least 10.5% chromium along with iron. Additional elements such as carbon, manganese, molybdenum, silicon, nickel, titanium, and niobium are added to produce a range of desired grades and properties. Stainless steel is used in automotive exhaust systems, automotive trim, cookware, cutlery, furnaces, and more. We manufacture over 50 stainless steel alloys formulated for varying durability, strength, aesthetics, fabrication needs, and temperature resistance.

What do you want protecting your BEV?

Cleveland-Cliffs Provides Superior Steel Solutions

C-STAR™ Protection 

Cliffs’ Steel Tubes As Reinforcement – known as C-STAR™ protection ─ when used in combination with structural components, contributes to the ability for structural components to absorb energy and/or deform in a more controlled and predictable way. A C-STAR structure may be used in electric, hybrid, or ICE vehicles as reinforcements in rocker panels to protect passengers and/or batteries from a side-impact collision. C-STAR protection may also be used to protect motors, engines, electrical components, passenger compartments, storage compartments, and any area in a vehicle where this design is implemented.

Cleveland-Cliffs Battery Enclosure 

The Cleveland-Cliffs Battery Enclosure is a sustainable and robust all-steel battery enclosure concept that meets stringent performance requirements. It is designed to fit any unibody architecture connecting to the rockers through the unique L-shaped tubular side rails. Our Battery Enclosure design utilizes an innovative one-piece bottom tray stamped with laser-welded blanks, which eliminates the need for additional reinforcements to protect the battery cells. It has novel L-shaped side rails, pushing the limit of design while providing robust protection for a side impact. The all-steel design enables a CO2 reduction of more than 70% as compared to a comparable all-aluminum design. It also has the advantage of thermal runaway mitigation.
