20Cr pepa kila wela

ʻO GB 20Cr alloy Steel he kila kiʻekiʻe Quenched and Tempered Alloy Structural steel, No ke kalapona haʻahaʻa kiʻekiʻe, Low alloy chromium, molybdenum, nickel case hardening steel. ʻO ka ʻaila Quenched & Tempered Hardness he 28-34 HRc. GB 20Cr kila Anealing hāʻawi hardenss emi ma mua o 250HB.20Cr Me ka haʻahaʻa kalapona maʻiʻo laulā, No laila, GB 20Cr hao kila i maikai weldability.

ʻO GB 20Cr alloy steel equivalent specification: ASTM A29/A29M, DIN EN 10083/3, JIS G4053 and GB/T 3077. GB 20Cr equivalent steel round bar and flat bars hiki ke oki i kou nui makemake. Hiki ke hoʻolako pū ʻia ke kila kila 20Cr hot rolled a forged steel bar, e hāʻawi ana i kahi kiʻekiʻe kiʻekiʻe o ke kila kila precision ground tool steel bar i kāu tolerances koi. Hāʻawi ʻia nā pahu mea kila kila GB 20Cr i nā ʻano poepoe, ʻāpana a me nā ʻano pālahalaha.
ʻO GB 20Cr alloy Steel he kila kila Quenched a Tempered Alloy Structural kiʻekiʻe. Aia ia i ke kalapona haʻahaʻa kiʻekiʻe, Low alloy chromium, molybdenum, nickel case hardening steel. ʻO ka ʻaila Quenched & Tempered GB 20Cr Steel Hardness he 28-34 HRc. ʻO GB 20Cr kila ʻO ka hāʻawi ʻana i ka Annealing paʻakikī ma lalo o 250HB. Me ka haʻahaʻa haʻahaʻa kalapona maʻiʻo, GB 20Cr alloy steel equivalents i maikai weldability.
Hoʻohana nui ʻia ʻo GB 20Cr pahu kila a me ka pahu kila wela wela no nā ʻano hana like ʻole i hoʻohana ʻia i nā ʻoihana kaʻa a me nā ʻenehana no nā mea paʻa a me nā mea like ʻole.

Hoʻohālikelike ʻia me ke kila 15Cr, ʻoi aku ka ikaika a me ka paʻakikī. ʻO ke anawaena paʻakikī koʻikoʻi i ka ʻaila hiki i 4-22mm, a ʻo ke anawaena paʻakikī koʻikoʻi i ka wai hiki i 11-40mm, akā ʻilihune kona paʻakikī. Aia ke ʻano o ka ulu ʻana o nā huaʻai, a ʻoi aku ka hopena o ke kinai ʻana i ka hoʻoilo i ka paʻakikī. No laila, ma hope o ka carburizing, koi ʻia ke kinai lua e hoʻomaikaʻi i ka paʻakikī o ka ʻāpana ʻāpana me ka ʻole o ka huhū; he kiʻekiʻe ka palaka anu a hiki ke huki ʻia i nā kūlana anu. ; ʻOi aku ka maikaʻi o ka mīkini ma lalo o ke kiʻekiʻe o ka mahana normalizing a i ʻole quenching a me ka tempering state, akā ʻilihune ma hope o ka annealing; ʻO 20Cr ka pearlite, me ka weldability maikaʻi, maʻamau ʻaʻole pono ka mālama wela ma hope o ke kuʻi ʻana, akā ʻo nā ʻāpana me ka mānoanoa ʻoi aku ka nui ma mua o 15mm pono e hoʻomaʻamaʻa mua ʻia ma mua o ke kuʻi ʻana.
