What is Low-Temp Carbon Steel?

Low-Temperature Carbon Steel (LTCS) like A333, A350 and A420 was developed for low temperature applications, such as cryogenics.

LTCS will have the same carbon content as Low and Medium Carbon Steel (0.05% to 0.30%) but will typically be impact tested at -50° F and may be Nickel plated, which allows for use in low-temperature applications.
