What is A352 LCC?
ASTM A352 LCC (UNS J02505) is an impact-tested cast carbon steel for low-temperature pressure-containing service, supplied normalized and tempered or quenched and tempered, and sitting the third strength tier above LCB. Default properties are 315 MPa yield, 525 MPa tensile, 26 % elongation, 155 HB and service to 425 °C, with Charpy qualification at −46 °C. Engineers specify it for cast valve and pump shapes that ambient-grade carbon steel cannot cover in cold service. It has no inherent corrosion resistance and must be coated; A216 WCB is the cheaper choice for ordinary temperatures. A352 LCC has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,425°C (2,597 °F). A352 LCC has a yield strength of 315 MPa (45.7 ksi) and a tensile strength of 525 MPa (76.1 ksi) — weaker than 82% of steel grades. Elongation at break is 26% and the elastic modulus is 202 GPa (29.3 Msi).

Working with A352 LCC
Is A352 LCC easy to machine?
Machines like WCC/A216 carbon steel castings — carbide tooling, 120–180 m/min; watch for hard skin, sand inclusions and shrinkage porosity near risers.
Can A352 LCC be welded?
Readily welded with E7018 / ER70S-x low-hydrogen consumables; preheat 100–150 °C for heavy sections and re-temper or PWHT major repairs to preserve −46 °C CVN.
Can A352 LCC be formed, bent or molded?
Green sand or no-bake sand casting with generous risering; mandatory normalize+temper (or quench+temper) after casting to refine grain and pass low-temperature impact tests.
