EN 10083-1:1996 C22E Steel: Specifications & Listings
EN 10083-1:1996 C22E: A low carbon special steel for quenching and tempering to EN 10083-1:1991 + A1:1996 (steel number 1.1151), with sulphur max. 0.035%. Supplied as semi-finished products, bars, rod, wide flats, sheet, plate and strip, and forgings (clause 1.1). Quenched and tempered tensile strength 500 to 650 MPa for ruling sections up to 16 mm.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.

Pair grade
C22R has the same limits except sulphur, controlled 0.020 to 0.040
Improved machinability
Steels with lead or higher sulphur, up to about 0.100% S, may be supplied on request (Table 3, note 3)
Restricted options
Without hardenability or quenched and tempered or normalized property requirements, the carbon range may be restricted to 0.05% and/or the sum Cr + Mo + Ni to max. 0.45% by agreement (Table 3, note 5)
Elements not quoted in Table 3 are not intentionally added without the purchaser's agreement, other than for finishing the heat. With hardenability requirements, slight deviations within Table 4 are permitted except for carbon, phosphorus and sulphur.

Re is the upper yield strength or, if no yield phenomenon occurs, the 0.2% proof strength; A on gauge length 5.65 times the root of the original cross section; KV on longitudinal Charpy V-notch test pieces, average of 3 values, no single value below 70% of the minimum average value. Ruling sections as in Annex A. Sizes not listed are not covered by the standard.
