9、rial.Although it is customary industry-wide to usethe term“pound”(for example,75 lb),following the baseweight designation,base weight is correctly used only to definenominal material thickness,and is not a measure of the weightof a base box.3.1.3 black plate,nlight-gage,low-carbon,cold-reducedsteel
10、intended for use in the untinned state or for the productionof other tin mill products.It is supplied only in a dry or oiledcondition.3.1.4 box annealing,na process involving slow heating ofcoils to a subcritical temperature,holding,and coolingtherefrom,to soften the strip and relieve stresses produ
11、cedduring cold reduction.It is accomplished in a sealed container.By introducing and maintaining an inert or slightly reducingatmosphere during the cycle,a relatively bright surface isobtained.3.1.5 bright finish,na surface that has a melted tincoating.3.1.6 bundle,na unit containing two or more pac
