◎ Elements not listed in this table shall not be intentionally added to the steel without the agreement of the purchaser except for finishing the cast. All appropriate precautions are to be taken to avoid the addition of such elements from scrap and other materials used in production which would impair mechanical properties and the suitability of the steel.

◎ More stringent carbon content ranges can be agreed upon at the time of inquiry and order.
① Particular ranges of sulphur content may provide improvement of particular properties. For machinability a controlled sulphur content of 0,015% to 0,030% is recommended and permitted. For weldability, a controlled sulphur content of 0,008 % to 0,030 % is recommended and permitted. For polishability, a controlled sulphur content of 0,015 % max. is recommended

◎ T-thickness；l-longitudinal；t-trasverse
◎ +A=soft annealed；+QT=quenched and tempered；+P=precipitation hardened；+AT=solutiong annealed；+SR=strength relieved

① T＜3mm: apply for test pieces with a gauge length of 80mm and a width of 20mm；test pieces with a gauge length of 50mm and width of 12.5mm can be used. T≥3mm: values apply for test pieces with a gauge length of 5.65√S0
② For thickness above 75mm, the mechanical properties can be agreed. Plate may also be delivered in the annealed condition; in such case the mechanical properties are to be agreed at the time of enquiry and order.
