Mechanical Properties

Features and Applications

• Applicability in joint welding of steels with high Mo-contents to steels with Ni-based alloy steels, joint welding of different types of steels, and in welding of low-alloyed problematic steels
• Suitablity for use in manufacture processes of pressure vessels with service temperatures between -196°C and + 550°C • High resistance to creep, to high temperatures, and to low temperatures (cryogenic applications) • Resistance to formation of oxide layers at temperatures up to 1200°C • Loss of elasticity at temperatures between 600°C - 800°C. • High strength against hot cracking. • General tendency towards diffusion of carbon at high temperatures or towards heat treatments of different materials. • Very high resistance to stress corrosion and to pitting corrosion (PREN 52). • Resistance to thermal shocks • Austenitic-structured stainless material with low coefficient of thermal expansion. • Very excellent performance in TIG welding.
• Use of Ar or Ar+He mix as shielding gas.

Current Type
