Bright annealing solution a H angao mfiridwuma de ma no yɛ bright anneal ed tube a ɛyɛ mmerɛw wɔ mu ne akyi soro, pɛpɛɛpɛ dimensional tolerance, ahoɔden a ɛkorɔn, corrosion resistance a ɛyɛ den ne nea ɛkeka ho. Ɔkwan bɛn so na wobetumi anya tube a ɛte saa?
Wɔde austenitic stainless steel di dwuma kɛse wɔ ɔmanfo, mfiridwuma ne asraafo mu. Ɛwɔ hɔ wɔ nneɛma ahorow mu, te sɛ nnua, abaa, ntama, ntama, nhama, foil, tubing, tubing, fittings, flanges ne forgings afoforo.
Sɛ wɔde dade a ɛnyɛ den no yɛ hyew wɔ fononoo a ɛyɛ mmerɛw mu a, chromium fã a ɛwɔ austenitic stainless steel mu no ne oxygen a ɛwɔ mframa mu no bɛyɛ adwuma ma ayɛ oxide a ɛyɛ fitaa, a wɔfrɛ no 'scale', a ɛsɛ sɛ wɔde pickling process yi fi hɔ.
Annealing ano aduru a ɛhyerɛn no betumi ama saa adeyɛ yi ayɛ papa. Sɛnea ɛbɛyɛ a wobɛkɔ so ayɛ fɛ no, kora mfitiase dade hyerɛn no so na kwati sɛ wobɛhyew no, ɛsɛ sɛ wɔma dade a ɛnyɛ den a ɛyɛ austenitic no yɛ hann a ɛma ɛyɛ hyew wɔ ahobammɔ anaasɛ vacuum mu na amma ne kɔla ansakra. Wobetumi ayɛ austenitic stainless steel ahorow nyinaa annealed. Wim tebea a ɛbɔ ho ban no betumi ayɛ hydrogen a ɛho tew, ammonia a wɔatetew mu, anaasɛ ɛtɔ mmere bi a ɛyɛ vacuum. Mframa a ɛbɔ ho ban no siw austenitic stainless steel products no ani oxidation bere a wɔreyɛ annealing no.
Enti annealing ano aduru a ɛhyerɛn no wɔ mfaso horow a edidi so yi:
1, hyerɛn annealing nyɛ nko na ɛtew dade pipe hardness, ma ductility no tu mpɔn, ɛma plasticity tu mpɔn, na mmom ɛnyɛ den sɛ wobetwa na ayɛ nwini deformation nso.
2, ma corrosion resistance tu mpɔn denam intergranular carbide precipitation a woyi fi hɔ so, sɛnea ɛbɛyɛ a sɛnea ɛte wɔ soro no yɛ fɛ. Refining grain ne uniform steel structure ne composition, ma dadeɛ no su tu mpɔn, nanso siesie ma ɔhyeɛ a wɔde yɛ adwuma nso.
3, yi residual internal stress a ɛwɔ dade mu no fi hɔ, siw deformation ne cracking ano.
4. oxidation ne decarbonization ba bere a ɛreyɛ hyew na ayɛ nwini wɔ annealing a ɛyɛ mmerɛw mu, enti wɔayɛ dade a wɔde ɔhyew ayɛ no ho adwuma foforo, na ɛma dade a wɔhwere ne ne bo yɛ kɛse.
5. Nya oxidation biara a ɛyɛ hyew, corrosion resistance a ɛyɛ papa.

Sɛ wɔde toto ɔfasu a wonya denam annealing ne pickling a ɛyɛ mmerɛw so a, esiane sɛ oxidation nhyehyɛe biara nni hɔ nti, chromium a enni hɔ no so tew wɔ soro, na ne corrosion resistance no ye bere a wɔayɛ no fɛfɛɛfɛ awie no.
6. Aduru a ɛyɛ hyew a wɔde bɛyɛ adwuma de akura nea ɛrehuruhuruw no awiei no, wontumi nyɛ ho adwuma bio na wonnya ani a ɛhyerɛn.
