304 / 304L Stàilinn Seamless Tubing
Ro-ràdh Bathar
Tha alloys 304 (S30400) agus 304L (S30403) steels stainless nan eadar-dhealachaidhean den 18 sa cheud chromium - 8 sa cheud nicil austenitic alloy, an alloy as eòlaiche agus as trice air a chleachdadh anns an teaghlach stàilinn gun staoin. Tha feartan saothrachaidh sàr-mhath aig stàilinn stainless 304 / L. Tha cho furasta ‘s a tha e a’ leigeil leis a bhith air a chruthachadh gu furasta airson sèididh, lùbadh agus coiling. Bidh deagh innealachadh agus susbaint ìosal sulfur a’ brosnachadh weldability sàr-mhath ann an tagraidhean a dh ’fheumas e.
Tha neart àrd, sàr-chrìonadh an aghaidh creimeadh agus susbaint gualain air a lughdachadh a’ dèanamh Alloy 304 agus 304L Stainless Steels feumail airson tagraidhean far a bheil feum air tàthadh. Tha cleachdadh a’ toirt a-steach cumadh ailtireil agus trim, pàirtean tàthaichte de uidheamachd giullachd gnìomhachas ceimigeach, aodach-fighte, pàipear, cungaidh-leigheis agus ceimigeach.
Is e buannachdan eile a tha an aghaidh oxidation, cruth sàr-mhath, furasta saothrachadh agus glanadh, co-mheas neart gu cuideam sàr-mhath agus cruas math aig teòthachd cryogenic Airson àrainneachdan a tha gu math creimneach, is fheàrr an susbaint nas ìsle de Type 304L air sgàth gu bheil e nas dìonachd an aghaidh creimeadh eadar-roinneil.
Tha stàilinn stainless Type 304L na dhreach gualain neo-ìosal den stàilinn 304alloy. Bidh an susbaint gualain as ìsle ann an 304L a’ lughdachadh sileadh carbide millteach no cronail mar thoradh air tàthadh. Mar sin faodar 304L a chleachdadh “mar tàthadh” ann an àrainneachdan fìor choire, agus tha e a’ cur às don fheum air annealing.
Tha feartan meacanaigeach beagan nas ìsle aig an ìre seo na an ìre àbhaisteach 304, ach tha e fhathast air a chleachdadh gu farsaing air sgàth cho sùbailteachd ‘s a tha e. Coltach ri stàilinn stainless Type 304, bidh e air a chleachdadh gu cumanta ann an grùdaireachd lionn agus dèanamh fìon, ach cuideachd airson adhbharan taobh a-muigh gnìomhachas a’ bhidhe leithid soithichean ceimigeach, mèinnearachd agus togail. Tha e air leth freagarrach airson a chleachdadh ann am pàirtean meatailt leithid cnothan agus boltaichean a tha fosgailte do uisge saillte.
