ASTM B75 Seamless Copper Tube Engineering Daim Ntawv Thov

Khoom Taw Qhia:

Cov khoom ntawm kev tsim khoom yuav tsum yog billet, cam khwb cia qws los yog raj. Lub raj yuav tsum tau tsim los ntawm kev ua haujlwm kub thiab txias ua haujlwm, yuav tsum tau txias txias kom tiav qhov loj me thiab phab ntsa tuab, thiab yuav tsum tau ua haujlwm nyob rau hauv txias rub lossis annealed tempering.

Cov kev cai ntawm grain loj, hluav taws xob loj resistivity thiab loj yog teev. Cov kev sim tshwj xeeb muaj xws li: particle loj, resistivity, tensile zog, yield zog, hardness test, round rooj expansion test, microscopic soj ntsuam, hydrogen embrittleness test, electromagnetic (eddy tam sim no), static siab, siab kuaj thiab lwm yam tsis-destructive xeem.
