Chemical Composition (% Weight)
Heat & Product Analysis🛡️ Service Compatibility
Impact tested down to -45°C (-50°F). Standard for LPG, cold hydrocarbons & cold climates.
Ideal for low-temp oil & gas process lines.
Suitable for steam & process up to 343°C (650°F).
Requires NACE MR0175 compliance and controlled hardness ≤22 HRC.
Limited to -45°C. For LNG (-162°C), use Austenitic Stainless Steel (304L/316L).
🔥 Welding & Heat Treatment
10°C min; 95°C for t > 19mm. Maintain interpass temp ≤ 230°C to preserve low-temperature notch toughness.
Required for nominal wall thickness t > 19mm (holding temp 590°C–630°C per ASME B31.3).
Mandatory Charpy V-notch impact testing at -45°C (-50°F) for base metal, HAZ, and weld deposit per ASTM A333.
