Difference between LTCS and ITCS

[Xeros]

Hi, i'm Xeros

LTCS is Low Temperature Carbon Steel and ITCS is Impact Tested Carbon Steel.

I think that ITCS is Carbon Steel tested by Charp impact test.

What is LTCS?
For example, SA516-70 with normalizing could be used with or without impact test as per temperature and thickness, accordance with UCS-66 on ASME.

SA516-70 with normalizing could be used with impact test is LTCS? or without is LTCS? or both is LTCS?

What is LTCS's standard and definition?

Best regards,

I don't believe any formal definition exists other than the acronym for low temperature carbon steel, and what you described as impact tested carbon steel. Low temperature and impact requirements for carbon and low alloy steels are usually defined by the applicable code or standard.
