1. Fɛn minnu bɛ kɛ:
• Fɛn minnu bɛ kɛ ɲɔgɔn fɛ, olu ye nɛgɛ ye min tɛ sɔgɔ (i n’a fɔ SUS304) ani nɛgɛ karɔbɔli. Nɛgɛ min tɛ sɔgɔ, o bɛ se ka sɔgɔsɔgɔ kosɛbɛ, wa a bɛnnen don sigidaw ma minnu ka kan ka kɛ kosɛbɛ ji la ani nɔgɔ kɛlɛli la. Carbon steel ka dɔgɔ ni-Sɔrɔdasi ye ani a fanga ka bon ka se ka baara kɛ ni a ye.
2. Sanfɛ furakɛli:
• A ka c’a la, nɛgɛ min tɛ sɔgɔ, o tɛ furakɛli wɛrɛ kɛ a la, wa a bɛ se ka to a kulɛri la. Karɔbɔni nɛgɛ bɛ se ka kɛ sababu ye ka farikolo yɔrɔw furakɛ i n’a fɔ galon ni passivation walasa k’a ka sɔgɔli kɛcogo ɲɛ.
3. Ji tɛ se ka don min na:
• Ji tɛ se ka kɛ nɔnɔ minnu na, olu kɔnɔna bɛ u ka ji mabɔ u dilanni na. A ka c’a la, kɔnɔna jiriw fiyentɔw ni kunkolo kɛrɛnkɛrɛnnen dɔ bɛ kɛ ka ji bali ka don a la ka a siri ni kuru ni nut ye.
4. A sigicogo:
• A ka c’a la, nugu minnu tɛ ji bɔ, olu bɛ bila ni riveting minɛn kɛrɛnkɛrɛnnenw ye. Nut staffoff bɛ riveted to the plate ka kɛ kɔnɔna nut nafama ye, o bɛ se ka siri ka don a nɔ na.
5. Baarakɛcogo paramɛtɛrɛw:
• Tensile strength (Tensile fanga) : ka M3 yɛrɛ ta-Ji tɛ se ka jɔ cogo min na, o bɛ kɛ ni SUS304 nɛgɛ ye min tɛ sɔgɔ i n’a fɔ misali, u ka tension fanga tɛ dɔgɔya 520 MPa ma ; M4 jɔli fanga fana bɛ o cogo kelen na. Karɔbɔli nɛgɛw jɔli fanga bɛ danfara ka kɛɲɛ ni nɛgɛ hakɛ ye, nka a ka c’a la, a bɛ se 300-600 MPa ɲɔgɔn ma.
