Applicability and limitations

GB/T 5216—2004 original Tables 1/2 and 6.1, ladle-analysis mass fraction wt%; retain the actual 2004 edition.

For high-quality steel, Note a to Table 1 adds A before H (e.g. 40CrAH); P/S by quality level and residual Cu/Cr/Ni follow Table 2; do not mix with the 2014 edition.

Under 6.1.3, Cu≤0.20% for hot-pressure processing. If the purchaser requires S 0.020–0.035%, add S before H; the sulfur tolerance ±0.005 is separately stated and does not expand the default range.

Table 1 alloy-element ranges take precedence over Table 2 residual limits; a blank means unspecified, not zero.

H/HH/HL hardenability bands, delivery condition, hardness and suitability for cold-heading processes require separate verification; this does not automatically create a supply product.
