AISI 4145H Cold DRAWN SEAMLESS EPT TUBES DRILL EPTS /AISI 4145H High TENSILE HOLLOW BAR
1.EPT Introduction
AISI 4145H is a chromium molybdenum good quality alloy metal specification. As a large tensile steel quality AISI 4145H is mainly provided in the hardened and tempered issue to thirty-36EPTc selection to AISI 4145H modified. With a slightly larger carbon material AISI 4145H is comparable to AISI 4140 in that it delivers good ducEPTTty, EPT resisting traits merged with resistance to wear.
2.Software
AISI 4145 is a lot more common in more substantial diameters thanks to its elevated energy and hardenability. It is typically used in the down gap drilling equipment this kind of as drill collars. Other purposes incEPTT factors exposed to weighty strain, this kind of as shafts, EPT, bolts etc. AISI 4145H can also be utilised in hardened condition as EPTT elements uncovered to heavy dress in.
