Best in class welding of stainless steels.

Stainless steels are a group of iron-based alloys that contain at least 10.5% chromium, which provides exceptional corrosion resistance by forming a passive oxide layer on the surface.

This unique composition provides high strength, excellent corrosion resistance, and good toughness, but also makes welding more complex compared to standard stainless steels.

This class of metals includes various grades, such as austenitic, ferritic, martensitic, and duplex, each with distinct properties tailored to specific applications.

Stainless steels are widely used in construction, chemical processing, food production, aerospace, and marine environments due to their versatility, durability, and resistance to rust, stains, and wear.

Stainless steel weld
  • Austenitic

    Austenitic stainless steels (e.g., 304, 316) are known for their excellent formability, corrosion resistance, and weldability.

  • Ferritic

    Ferritic (e.g., 430) and martensitic steels (e.g., 410) are more magnetic and typically offer higher strength or hardness.

  • Duplex Stainless Steels

    Duplex stainless steels, which combine both austenitic and ferritic phases, provide enhanced strength and resistance to stress corrosion cracking.
