ASTM · United States · 82 designations # A 182 Grade F22 A 182 Grade F22 is a designation in ASTM for the material held under material number 1.7380, also listed as 10CrMo9-10. It is a material in the category Heat-resistant structural steels. We list 82 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, ASTM, BS, AFNOR, UNE, ISO, JIS, GB, GOST, UNI, SS, ČSN, PN, STN, SRPS, MSZ, STAS, BDS and ÖNORM. - [*Material no.* **1.7380**](/materials/material-no/1.7380 "Material no.: 1.7380") - [*Category* **Heat-resistant structural steels · 62 grades**](/categories/heat-resistant-structural-steels "Category: Heat-resistant structural steels · 62 grades") - *Designations* **82** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=cc9d06d4-2391-4be8-87ba-ffdc76a785ea&designation=997f2535-62cd-4494-ab98-daca69550d18 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/astm/a-182-grade-f22.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 10CrMo9-10 This grade’s own name](/materials/din-en/10crmo9-10 "DIN / EN 10CrMo9-10") - [UNS K21390 This grade’s own name · 3 grades on that route](/materials/uns/k21390 "UNS K21390") - [ASTM A 182 F 22 Class1 This grade’s own name](/materials/astm/a-182-f-22-class1 "ASTM A 182 F 22 Class1") ## About Heat-resistant structural steels Heat-resistant structural steels are structural steels designed to retain useful strength and dimensional stability at elevated temperatures. They are used for load-bearing components in hot-service equipment where mechanical performance must be maintained during heating. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 82 designations · 21 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.
