AISI SAE 4130 4140 4145H Steel Porowhita Pae Hollow Rod
Ngā āhuatanga
4130 4135 4140 4145H tutaki maitai he waro koranu maitai iti.No Chrome-Molly te koranu kei roto te chromium me te molybdenum hei whakakaha.
4130 pae maitai a tawhio noa he pai te kaha mahi, iti deformation tukatuka, me te ātete rohirohi pai.No te reira ki te kāwai o reo ki te tiketike whakapakeke kaha maitai.I muri i te maimoatanga o te wera, he pai te kaha o te 4140 me nga taonga miihini matawhānui, te kaha o te tukanga, me te hua nui.Ko te mahana o te ratonga he 427 nga nekehanga Celsius.
Ko te 4140 he kaha teitei, he pakari te kaha, he uaua, he rereke te ahua i te wa e tineia ana.He nui te kaha ngokingoki me te kaha mau tonu i te pāmahana teitei.Ka whakamahia mo te hanga i nga mahi whakahiato e hiahia ana kia kaha ake te kaha me nga waahanga kua tineia me te werawera nui atu i te 4135 maitai, penei i nga taputapu nui mo te hikoi hikoi, nga taputapu tuku whakatairanga, nga toki o muri, nga rakau hono me nga topenga puna e tino utaina ana.
