Steel — AISI/SAE 4-digit 4140 First two digits = steel series (41xx = Cr-Mo), Last two digits = carbon content in 0.01% (0.40% C)
Steel — AISI Series Code 1xxx = Carbon, 2xxx = Nickel, 3xxx = Ni-Cr, 4xxx = Mo, 5xxx = Cr, 6xxx = Cr-V, 8xxx = Ni-Cr-Mo
Stainless — AISI Type 304 / 316 / 430 3xx = Austenitic, 4xx = Ferritic or Martensitic

JUS — Yugoslav Standard

JUS (Jugoslovenski standard) was the technical standard system used in the Socialist Federal Republic of Yugoslavia, and continued to be applied in successor states (BiH, Serbia, Croatia, Slovenia, Macedonia, Montenegro) until full harmonisation with EN standards.

In BiH, JUS standards were gradually replaced by BAS EN (Bosansko-hercegovački standard European Norm) standards, but JUS designations are still found in older technical documentation, drawings and contracts.
