They are used for pressure vessels, piping and process equipment exposed to hydrogen-containing environments, where resistance to hydrogen ingress and loss of toughness is important. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 48 designations · 14 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

They are withheld rather than shown against a guessed condition. Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## Heat treatment **GB 2100-1980** Order not stated by the source - Quenching 1150–1180 °C Cooling Water - Ageing 485–570 °C Cooling Air The source lists these operations without stating an order or an alternation.
