321 Cov Yeeb Nkab Steel Hlau

321 Cov yeeb nkab steel hlau yog ib hom stainless hlau yeeb nkab paub rau nws cov khoom siv kub heev, corrosion tsis kam, thiab ruaj khov. Nws yog siv thoob plaws ntau yam lag luam, suav nrog Aerospace, kev ua yeeb yam, cov zog hluav taws xob, thiab cov chaw muaj dej hiav txwv. Nws cov kev pab cuam muaj xws li kub thiab corrosion tsis kam, zoo weldability, thiab muaj zog neeg kho tshuab.

1. Muaj pes tsawg leeg

Chromium (CR): {{17-19% - Muab corrosion tsis kam thiab lub zog.

Nickel (NI): {9-12% - txhim kho kev txhim kho thiab tawv.

Titanium (ti): Feem ntau ntxiv ntawm 5 zaug ntawm cov ntsiab lus carbon - ruaj ruaj cov khoom siv thiab tiv thaiv carbide nag lossis tiv thaiv cov nag los nag.

Cov pa roj carbon (c): Ntau tshaj ntawm 0. 08% - Cov txiaj ntsig cov pa roj carbon qis txo qhov kev pheej hmoo ntawm cov dej nag carbide.

2. Thaum tshav kub tiv thaiv

Kev kub siab rau kev rau siab: tuaj yeem tiv taus kub txog 900 degree (1652 degree f) tsis muaj oxidation lossis tsis muaj zog.

Thermal Stability: tswj cov khoom siv neeg kho mob thaum lub siab ntsuas kub, ua rau nws haum rau cov ntawv thov kub siab.

3. Corrosion Kuj

Oxidation tsis kam: Zoo heev tiv taus rau oxidation thaum kub, ua rau nws haum rau cov ntawv thov kub thiab oxidative ib puag ncig.

General corrosion resistance: muab cov kev tsis kam ua rau ntau yam tshuaj, nrog rau cov kua qaub thiab alkalis.

Intergranion Corrosion Kuj: Titanium Ruaj Kheesilization pab tiv thaiv cov nag los nag thiab txo qhov kev pheej hmoo ntawm kev sib cav sib ceg, tshwj xeeb tshaj yog thaum vuam.

4. Cov Khoom Siv Neeg Kho Tshuab

Lub zog: zoo tensile thiab tawm los ua kom haum rau cov qauv thiab load-cov kab ntawv thov.

Ductility: tswj qhov yooj thiab tawv ntawm qhov kub.

Lub Hardness: Feem ntau, nws muaj lub hardness uas tshuav hluav taws xob uas muaj zog thiab tawv.

5. Weldability

Yooj yim ntawm vuam: Zoo Weldability nrog cov qauv vuam. Qhov sib ntxiv ntawm titanium tiv thaiv carbide nag lossis ua kom muaj zog thaum vuam, kom ua kom muaj zog weld sib koom tes.

Txo carbide nag los daus: stidilization nrog titanium minimizes teeb meem cuam tshuam rau kev tsim carbide thaum vuam.
