A333 Grade 6 vs Grade 3 Comparisons
A333 Grade 6 (Standard LTCS)
- • Carbon Steel base alloy
- • Impact tested down to -45°C (-50°F)
- • Widely available and cost-effective
- • Ideal for cold-weather pipelines, general refrigeration, and LPG lines.
A333 Grade 3 (Nickel Alloyed)
- • Contains ~3.5% Nickel (Ni)
- • Impact tested down to -100°C (-150°F)
- • Higher tensile strength (65 ksi)
- • Crucial for extreme deep cryogenic processes and specific LNG storage applications.
