316/316L igwe anaghị agba nchara

Alloy 316 / 316L bụ molybdenum-agba austenitic igwe anaghị agba nchara. Ọdịnaya nickel na molybdenum dị elu dị na ọkwa a na-enye ya ohere igosipụta mma n'ozuzu corrosion eguzogide Njirimara karịa 304, Alloy 316/316L igwe anaghị agba nchara na-ọtụtụ ebe na azụmahịa na ulo oru ngwa. Ọ bụ ihe austenitic alloy nwere ezigbo weldability na ọmarịcha malleability.

Ọdịiche dị n'etiti 316 na 316L

Igwe anaghị agba nchara 316 nwere carbon karịa n'ime ya karịa 316L. Nke a dị mfe icheta, dịka L na-anọchi anya "dị ala." Mana n'agbanyeghị na o nwere obere carbon, 316L yiri 316 n'ihe fọrọ nke nta ka ọ bụrụ ụzọ ọ bụla. Ọnụ ego yiri nke ahụ, ma ha abụọ na-adịgide adịgide, na-eguzogide corrosion, na nhọrọ dị mma maka ọnọdụ nrụgide dị elu.

316L, Otú ọ dị, bụ nhọrọ ka mma maka oru ngo nke na-achọ ọtụtụ ịgbado ọkụ n'ihi na 316 nwere ike ịdaba ire ere karịa 316L (corrosion n'ime weld). Agbanyeghị, enwere ike ịkagbu 316 iji gbochie ire ere weld. 316L bụkwa nnukwu igwe anaghị agba nchara maka oke okpomọkụ na iji corrosion dị elu, nke mere na ọ na-ewu ewu maka ọrụ owuwu na ọrụ mmiri.

Ma 316 ma ọ bụ 316L bụ nhọrọ kacha ọnụ ala. 304 na 304L yiri ma ọnụ ala dị ala. Ma ọ dịghịkwa ihe na-adịgide adịgide dị ka 317 na 317L, nke nwere ọdịnaya molybdenum dị elu ma dị mma maka nguzogide corrosion n'ozuzu ya.
