Material for Low Temperature Service

This Standard covers toughness requirements for carbon and low alloy steels used for pipe and piping components in service at a design minimum temperature within the range of -18°C to -45°C. The requirements in this standard are more restrictive than those in the ASME B31.3 code.

For definitions of design minimum temperatures, including auto-refrigeration service, refer to SAES-L-310, or SAES-L-410 as applicable.
