▁more ▁capacity ▁to ▁draw ▁from ▁as ▁the ▁metal ▁co ols ▁and ▁shr inks . ▁Att ention ▁should ▁be ▁paid ▁to ▁the ▁thick ness ▁of ▁m old ▁cav ities , ▁as ▁th inner ▁areas ▁will ▁cool ▁quick er ▁than ▁th icker ▁areas , ▁which ▁can ▁create ▁internal ▁stress ▁points ▁that ▁can ▁lead ▁to ▁f ract ure . ▁▁ ▁Mol ten ▁steel ▁is ▁also ▁less ▁fluid ▁than ▁mol ten ▁iron , ▁making ▁it ▁more ▁difficult ▁to ▁pour ▁and ▁fill ▁intr icate ▁g aps ▁in ▁a ▁m old ▁cav ity . ▁Mol ten ▁steel ▁is ▁also ▁more ▁likely ▁to ▁react ▁with ▁internal ▁m old ▁surfaces , ▁making ▁for ▁more ▁un predict able ▁results . ▁ ▁Mach in ability ▁ ▁Cast ▁parts ▁often ▁require ▁mach ining ▁to ▁achieve ▁accurate ▁toler ances ▁and ▁desired ▁surface ▁finish es . ▁Car bon ▁steel ▁is ▁the ▁easiest ▁type ▁of ▁steel ▁to ▁machine . ▁High - car bon ▁steel ▁can ▁be ▁more ▁time ▁cons uming ▁to ▁cut ▁or ▁gr ind , ▁and ▁will ▁wear ▁tools ▁faster . ▁Low - car bon ▁steel ▁can ▁get ▁g ummy , ▁making ▁it ▁difficult ▁to ▁work ▁with . ▁▁ ▁Gener ally , ▁the ▁presence ▁of ▁allo ys ▁used ▁to ▁increase ▁mechanical ▁performance ▁often ▁make ▁mach ining ▁more ▁difficult . ▁ ▁D amp ing ▁ability ▁ ▁Cast ing ▁is ▁often ▁a ▁valuable ▁means ▁to ▁creating ▁intr icate ▁parts ▁used ▁in ▁machine ▁applications ▁where ▁v ibration ▁is ▁often ▁a ▁factor . ▁Cast ▁steel ▁typically ▁has ▁a ▁lower ▁d amp ing ▁ability ▁than ▁cast ▁iron , ▁which ▁can ▁lead
