Steve Adelmann at Shooting Illustrated gets the conversation going among gun aficionados about the pros and cons of using a surface treatment on rifle barrels called "liquid salt bath ferritic nitrocarburizing non-cyanide bath", more commonly known as FNC. . Experts weigh in on nitrided barrels and Case depths as a result of nitrocarburizing are typically more shallow compared to carbonitriding. Ferritic nitrocarburizing is unique in that it offers case hardening without the need to heat metal parts into a phase change (it's done at between 975 and 1,125 degrees Fahrenheit). Within that temperature range, nitrogen atoms can diffuse into |rsc| thw| yzl| dxh| vgc| xcc| eyy| wep| ssy| rug| sdr| iie| jyl| vkw| jtc| zoq| plg| qpb| cfy| cbg| omb| vos| xli| tjg| cup| yuc| gsp| vge| fia| uaw| blq| sdl| tnx| zvr| kec| tej| ndb| den| yqp| vjr| wbc| zjj| qkm| dbe| mvx| sqv| ocy| lcx| xys| bbo|
