Applicability and limitations
General composition requirements for manufacturer data; Al and Ti must simultaneously satisfy the individual element range and the combined range. Special orders may specify stricter composition or grain size; general conditions shall not be treated as guarantees for all orders. The documentation separately lists 800H special orders with C≤0.08% and Al+Ti as 0.4–0.7%, which must be adopted only after explicit order agreement and does not default to override general requirements.. Only a lower limit of 39.5% is given for Fe; elements not listed in this table shall not be filled as zero.
