1.0619 — ASTM Equivalent

Holding a datasheet that specifies 1.0619 (DIN/EN)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.

What is the ASTM equivalent of 1.0619?

1.0619 is a DIN/EN designation corresponding to ASTM A216 WCB (Carbon Steel WCB) and A217 WC9 (Chrome-Moly WC9 (2.25Cr-1Mo)) and A352 Grade LCC (Low Temperature Carbon Steel LCC) and A216 WCC (Carbon Steel WCC) for industrial valve service. The full grade data is below - equivalence is by nominal chemistry and mechanical class, so confirm composition and heat-treat condition against the governing standard before substituting in critical service.

A216 WCB

Carbon Steel

Carbon Steel WCB - cast form.

Service temperature-29°C to +538°C

Nominal compositionC ≤ 0.30%, Mn ≤ 1.00%, Si ≤ 0.60%, P ≤ 0.035%, S ≤ 0.035%. Carbon equivalent: Ceq ≤ 0.50%.

Typical service: Steam service (up to Class 1500 with IBR certification); Water, cooling water, firewater; Crude oil and petroleum products

Also designated:161 Grade 430 [BS 1504]GS-C25 [DIN/EN]1.0619 [DIN/EN]SCPH2 [JIS]

A217 WC9

Chrome-Moly / Alloy Steel

Chrome-Moly WC9 (2.25Cr-1Mo) - cast form.

Service temperature-18°C to +593°C

Nominal compositionC ≤ 0.18%, Cr 2.00–2.75%, Mo 0.90–1.20%, Mn 0.40–0.70%. Martensitic after heat treatment.

Typical service: Main steam (MS) service - coal, gas, and nuclear power plants; Hot reheat steam (HRH); HP feedwater - Class 600–900, up to 593°C

Also designated:GP240GH [EN]1.0619 (not direct equiv.) [EN]GS-17CrMo55 [DIN]622 Grade 31 [BS 1504]

A352 Grade LCC

Carbon Steel

Low Temperature Carbon Steel LCC - cast form.

Service temperature-46°C to +345°C

Nominal compositionC ≤ 0.25%, Mn 0.50–1.20%, Si ≤ 0.60%, P ≤ 0.030%, S ≤ 0.030%. Impact tested at −46°C.

Typical service: LNG terminals and LNG storage tank valves; LPG and propane storage and transfer; Ethylene and propylene plants

Also designated:GP240GH [EN]1.0619 (approx) [EN]LT20 (approx) [BS]

A216 WCC

Carbon Steel

Carbon Steel WCC - cast form.

Service temperature-29°C to +538°C

Nominal compositionC ≤ 0.25%, Mn ≤ 1.20%, Si ≤ 0.60%, P ≤ 0.035%, S ≤ 0.035%. Carbon equivalent: Ceq ≤ 0.55%. Higher Mn than WCB gives elevated strength.

Typical service: High-pressure steam up to Class 900; Crude oil, refined products, and natural gas in high-pressure lines; Utility water and condensate at elevated pressure

Also designated:Group 1.1 (same as WCB) [ASME B16.34]GP240GH (1.0619) [EN]Grade 480 [BS]SCPH 2 [JIS]
