Product Description

BÖHLER L035 covers requirements of wrought 35cobalt-35nickel-20chromium-10molybdenum alloy (UNS R30035) in the form of bars.
These bars have been used typically for applications in Oil&Gas and CPI requiring a combination of high strength, good tension-tension fatigue strength, toughness, ductility, and exceptionally good corrosion resistance after subsequent aging but usage is not limited to such applications.
BÖHLER L035 is a nickel-cobalt base multiphase alloy system that has a unique combination of properties – ultra high strength, toughness, ductility and outstanding corrosion resistance. The alloy is able to be work-strengthened and aged to obtain strength levels of above 260 ksi (1793MPa) in its full strength and stress corrosion cracking resistance (SCC) for harsh environments. BÖHLER L035 alloy resists corrosion in hydrogen sulfide, salt water and other chloride solutions, as well as the mineral acids (nitric, hydrochloric, sulphuric). In addition, it has exceptional resistance to crevice cracking in seawater and other hostile environments.
The unique capabilities of BÖHLER L035 are derived from the alloy’s chemistry, premium melting technology, cold-working, and heat treatment. It is a vacuum induction melted (VIM), vacuum arc re-melted (VAR) superalloy.
