304H igwe anaghị agba nchara

Nkọwa

304H bụ austenitic igwe anaghị agba nchara, nke nwere 18-19% chromium na 8-11% nickel na kacha nke 0.08% carbon. 304H igwe anaghị agba nchara ọkpọkọ bụ ndị kasị vasatail na ọtụtụ ebe a na-eji ọkpọkọ na igwe anaghị agba nchara ezinụlọ. Ha na-egosipụta nguzogide corrosion dị oke mma, ike dị egwu, ịdị mfe nke imepụta ihe, yana nhazi pụrụ iche. N'ihi ya, a na-eji ya eme ihe dị iche iche nke ụlọ na azụmahịa. Igwe anaghị agba nchara 304H nwere ọdịnaya carbon a na-achịkwa nke 0.04 ruo 0.10. Nke a na-enye enwekwukwa elu okpomọkụ ike, ọbụna n'elu 800o F. Tụnyere 304L, 304H igwe anaghị agba nchara ọkpọkọ nwere ukwuu obere okwu na ogologo okwu creep ike. Ọzọkwa, ha na-eguzogide ọgwụ karịa 304L.

A kpọtụrụ aha n'okpuru bụ njirimara isi nke ọkpọkọ igwe anaghị agba nchara 304H nke Arch City Steel & Alloy nyere:

Nguzogide ọkụ:

  • Kwesịrị ekwesị maka ngwa okpomọkụ dị elu, ebe ọ na-enye ike dị elu na okpomọkụ karịa 500 ° C na ruo 800 ° C.

  • Ọkwa 304H na-enye ezigbo nguzogide oxidation na ọrụ oge na-adịghị anya ruo 870 ° C yana ọrụ na-aga n'ihu ruo 920 ° C.

  • A na-enwe mmetụta na oke okpomọkụ nke 425-860 ° C; ya mere akwadoghị ma ọ bụrụ na achọrọ nguzogide corrosion mmiri.

Nguzogide corrosion:

  • Ezigbo iguzogide corrosion na gburugburu oxidizing, yana acid organic na-eme ihe ike n'ụzọ kwesịrị ekwesị n'ihi ọnụnọ nke chromium na nickel n'otu n'otu.

  • Na-eme otu n'otu ebe n'ọtụtụ ebe na-emebi emebi

  • Enwere ike igosi ọnụego corrosion dị ala ma e jiri ya tụnyere ọkwa carbon dị elu 304.

Weldability:

  • Ọtụtụ usoro ọkọlọtọ agbadoro ngwa ngwa.

  • Enwere ike ịchọrọ ka anneal mgbe ịgbado ọkụ

  • Annealing na-enyere aka n'iweghachi nguzogide corrosion furu efu site na uche.

Nhazi:

  • Okpomọkụ arụ ọrụ akwadoro nke 1652-2102°F
  • A ga-ehichapụ ọkpọkọ ma ọ bụ tubes na 1900ºF
  • Ihe kwesịrị imenyụ mmiri ma ọ bụ mee ka ọ dị jụụ ngwa ngwa
  • 304H ọkwa bụ nnọọ ductile na ụdị mfe
  • Oyi akpụ na-enyere aka ịbawanye ike na ike nke ọkwa 304H
  • Ịkpụ akpụ oyi nwere ike ime alloy ntakịrị magnetik

Ike igwe:

  • A na-enweta nsonaazụ kacha mma na iji nwayọ nwayọ, mma mmanu mmanu, nri dị arọ karị, na ngwa ngwa dị nkọ

  • Isiokwu na-arụ ọrụ hardening na mgbawa imebi n'oge deformation.
