    50 HRC..... 465 custom vs 440c

    why do CO alloys have usually good wear resistance? Is it becose its hexagonal close packed shape?

    50 HRC..... 465 custom vs 440c

    thank you Maui,that was very good post about carbides you say it is generaly true that carbide containing steels/alloys outperform other non-carbide steels/alloys at same HRC,you didnt explain why.You explained very good the carbide stuff,but not why,at same hrc,why would carbide containing...

    50 HRC..... 465 custom vs 440c

    but generaly,do carbide containing steels outperform non-carbide steels in abrasion resistance if they are both at same HRC hardness? If I get 50HRC from carbides,is it superior type of hardness than if I get 50 HRC from martenistic heat threatment or cold working? Is there anything special...

    50 HRC..... 465 custom vs 440c

    I am only interested in abrasion resistance back to the topic,if I have two steel plates,both measing same HRC value but one contain carbides,will they have different scratch and abrasion resistance? Like the examples above,stellite vs 10-2-3 titanium at 48 hrc.... or custom 465 vs 440c at 50...

    what other parameters do you mean?

    50 HRC..... 465 custom vs 440c

    but why? Why would one 50 HRC steel cut hair and resist abrasion any different than another steel that have 50 HRC but also have carbides? I was thinking if the materials have same HRC,their abrasion resistance must be completly identical.Do carbide steels offer better abrasion resistance even...

    50 HRC..... 465 custom vs 440c

    There are two kinds of heat hardenable steels,those that have carbon so carbides are created,like 440c and then the PH martensite steels like 17-4 or custom 465. The carbide steels like 440c can have higher peak hardness than hardest PH steels like custom 465,but what if I heat threated and...

    opticaly transparent fluoro elastomer

    I am no expert on this,but I think PFA is not elastomer

    opticaly transparent fluoro elastomer

    I want a opticaly transparent,doesnt need to be perfect like glass,but it cant have yellow tint or other coloration. It must be elastomer,it must be some kind of "fluoro" or "perfluoro" type,but it cant be fluorosilicone.It also needs to be soft as possible,idealy I would want Shore A of 40 Is...

    how can i create filter?

    I want to filter my music,pcm/wav 16bit 44100hz files,can I create filter in Matlab and then use it on real music?
