Weldox 100 Corrosion Resistance

Weldox 100 is highly resistant to corrosion, thanks to the addition of chromium and molybdenum in its composition. Its corrosion resistance is comparable to that of stainless steel, making it an ideal material for use in harsh environments like marine and offshore applications.

Weldox 100 Heat Treatment

Weldox 100 undergoes a quenching and tempering process to achieve its exceptional strength and toughness. This process involves heating the steel to a high temperature and then rapidly cooling it to enhance its hardness. After quenching, the steel is tempered, which helps to reduce its brittleness and increase its toughness.

Weldox 100 Machining

While Weldox 100 is highly machinable, it requires specialized tools due to its high strength and hardness. CNC machining is ideal for Weldox 100, allowing manufacturers to produce exact, complex parts with minimal waste.

Weldox 100 Welding

Weldox 100 is a high-strength structural steel designed for use in welded structures. It provides excellent mechanical and welding characteristics and superior resistance to stress corrosion, cracking and fatigue. Its low weight makes it ideal for supporting significant, heavy components without sacrificing strength.


Weldox 100 is a high-strength steel renowned for its exceptional toughness, low weight, and resistance to wear and tear. Its unique combination of elements makes it suitable for demanding applications like marine and offshore environments, heavy-duty equipment, and structural applications. With its low carbon content, Weldox 100 is highly weldable, making it easy to fabricate and customize to meet specific application requirements. Whether you’re in the market for steel that can withstand high stress, severe weather conditions or heavy usage, Weldox 100 is an ideal choice.
