Yer ario i ngec mi piny: Stainless Steel vs. Alloy Steel—Yore mi poko kind tek pa tic ku leng pa piny ma rii pi kare malac
Lembe ma kwong: I ngei the lembe pa "Iron" I lembe ma pire tek mi yero piny ma moko kwo man tic pa piny ma kawoni, piny ario madongo mi thek pa steel—alloy steel man stainless steel—gibedo i wang lembe. Kadi bende piny ario eni gi rom ku jam piny ma juyubu ku cuma, kit migi mi kemikol man kite migi mi tic mi cing gi timo "binary opposition" ma tung tung. Lembe maeni mitu nyang ikum tung tung ma pire tek ikind piny ario ma pigi tek eni man telo jururyeko man jururyeko mi wil piny ikum kite mi timo yer maber loyo i tic.
I. "The Insurmountable Wall" pa ngec pa kemikol: Teko pa Chromium Piny ma pire tek ma poko stainless steel ku alloy steel utiye "entry threshold" ma nok pa piny **chromium (Cr)**.
(1) The Genetic Code of Stainless Steel: Kit ma "rust-free" pa stainless steel epe kudu kende kende, ento utiye kit kemikol ma juketho. Umitu obed ku 10.5% (nyo 12%) mi chromium. Ubedo rwom ma malu pa chromium ma weko wi piny eca doko piny ma nyap (ma romo 100 nm) ma gwoko chromium oxide ma copo cango gire. Filim eni ubedo piny ma juku pii, yamu, man kemikol ma rac.
(2) Yub pa alloy steel: I yore ma lac, alloy steel ubedo dul pa cuma ma juyiko ku piny matung tung (macalu nickel, molybdenum, vanadium, silicon, man mange). Gicopo bedu ku chromium, ento piny ma iye epe; tic migi madit utiye ni lubo tok piny maber pa cuma, ento ungo ni gwoko piny ma nyayu lyethu. Pieno, pol pa alloy steels gicungo iwi coatings ma woko nyo electroplating pi gwoko kwo pa piny.

| Core Value Axis: | Stainless Steel (ma wakwanu 300 series austenitic steel calu lanyuth) | Alloy steel (kwalo low-alloy high-strength steel calu lanyuth) |
| Piny ma pire tek: | Gwok pa ngom (Durability) | Teko pa cuma man tek pa cuma |
| Tic maber akeca: | Ecungo ikum oxidation, pitting, crevice corrosion, man stress corrosion cracking. | Teko ma malo pa yiku piny man kero mi rwinyo piny copo bedu ni kadhu kud i tic ku lyethu. |
| Tek/Duktility: | Pol kare enyutho ductility man weldability maber, ento tego pare nok. | Ductility moko juweko pi bedo tek man kero mi tingo pek. |
| Ber pa bey: | Kethu lim madwong, ento wel mi gwoko piny uromo zero, ma ukelo wel piny ma nok mi kwo. | Kethu lim ma kwong eca yot, ento gwoko piny ma jwigere kare ku kare mitire i saa mi tic. |
3. Poko tic mi tic: Nicaku i ngec mi kwo nituc i tic mi gedo
Tung tung eni i chemistry man kite migi nyuthu tic migi i tic mi kare eni:
Stainless Steel: Jagwok pa leng pa piny ma rii pi kare malac. Jutiyo kudu pol kare i kabedu ma cik ma tek mi gwoko leng pa kum, leng pa piny, man leng pa piny. Nicaku i jam tic mi yath, reactors mi yath, man kabedo mi kano cam man kongo nitundu i ot ma jugiero i dhu nam nyo i kabedo ma ngic, stainless steel ubedo piny maber pi gwoko piny ma jutiyo kudu pi kare malac man ma nyayu ngo piny ma rac.
Alloy Steel: The Backbone of Load-Bearing Limits. Bedo agonya kud i peko mi kabedu ma nyai, alloy steel timo tic ma pire tek ungo i kabedu ma mitu ciro peko madit, lworo, nyo lyethu man kero ma lee. Lanyuth uketho i iye piny ma jutiyo kudu pi podho pa ndege, piny ma pire tek ma tiyo kudu i injin pa mutukari, paip mi boiler ma tek, man jam tic matung tung ma tek man ma tek. Gitiye "ju ma pire tek ungo" mi tic ma tek man ma tek tek.
I ajiki: Anyim pa Rational Material Selectio
I lembe ma nok, kadi nang stainless steel utiye thenge moko pa alloy steel, i lembe mi diro, gi nyuthu paru ario matung tung mi yiku piny: acel mitu bedo ber pa piny, man mukende mitu kelo aloka loka madit i kum piny. Anyim pa yubu piny ma rieko mito ju ma gisomo tic mi yubu piny ni ketho wigi ikum bei piny ma jucaku kende, ento de ni timo sayusac ma thuc ikum tic migi ikum kwo pa piny, yeny mi gwoko gi, man beru pa tic migi, pi ni nwangu rwom maber ikind "kwo ma rondo ku rondo" pa stainless steel ku "high strength" pa alloy steel.
