410 kowiri tira

Ko te 410 he kowiri tira he kowiri tira i hangaia i runga i nga paerewa ASTM Amerika, he rite ki te 1Cr13 kowiri tira o Haina, S41000 (American AISI, ASTM). Waowa kei roto 0.15%, chromium kei roto 13%, 410 he kowiri tira: he pai te aukati te waikura, te machinability, nga matatahi kaupapa whanui, nga marere. 410 maimoatanga wera kowiri tira: maimoatanga otinga totoka (℃) 800-900 puhoi te whakamahana, 750 te whakamahana tere. Te hanganga matū o te 410 kowiri tira: C≤0.15, Si≤1.00, Mn≤1.00, P≤0.035, S≤0.030, Cr = 11.50 ~ 13.50.

Ka whakamahia e te American Iron and Steel Institute e toru nga mati hei tohu i nga momo karaehe paerewa o te kowiri tira ngawari. i roto ia ratou:

① Ko te momo chromium-nickel-manganese Austenitic he 200 raupapa, penei i te 201,202;

② Austenitic chromium-nickel momo he 300 raupapa, pērā i 301, 302, 304, 304L, 316, 316L, etc.;

③ Ferritic me martensitic kowiri tira he 400 raupapa, pērā i 405, 410, 443, etc.;

④ He 500 te raupapa rino chromium atete te wera,

⑤ Martensitic precipitation whakapakeke kowiri tira he 600 raupapa .

Whakatika āhuatanga

1) Te kaha teitei;

2) Machinability pai

3) Ka puta te pakeke i muri i te maimoatanga wera;

4) Aukume;

5) Kaore e pai mo nga taiao kino kino.

3. Te whānuitanga o te tono

Matatahi whanui, nga waahanga miihini, momo 1 tepu kai (te koko, te marau, te maripi, me etahi atu).
