Carbon Steel SA352 LCC is one of the most widely used Carbon Steels in industry. Typically referred to as a cast low temp steel, LCC is the common grade for regular temperature applications for cast steel valves. The three grades of ASTM A352/A352M are good for temperatures ranging from -50*F to 800* F (where corrosion resistance is not important).
Cast Valves for Low Temperature service are normally offered in A/SA352 Grades LCB(65ksi Tensile) and LCC(70 ksi Tensile). Grade LCA(60ksi Tensile) material is listed in Specifications A/SA352, but is not a standard production item for valves.
Other special materials are available on request (SA352 LCB, AISI 316L, Hastelloy, Monel, Alloy 20). SEAL RING - PTFE or metal types are available for any sizes and are interchangeable without any change up to 12" included.
ASTM A352 / A352M - 18a Standard Specification for Steel ...
Note 1: This specification covers the low-temperature requirements particularly pertinent for ferritic and martensitic steels. Certain grades of austenitic steel castings furnished in accordance with Specification A351/A351M have been found suitable for low-temperature service down to −300 °F [−184 °C] and others down to −425 °F [−254 °C].
