ASTM B348 Titanium Bar

Qhov no ASTM B348 Standard Specification yog rau annealed Titanium thiab Titanium Alloy Bars thiab Billets, Qib los ntawm qib 1 mus rau qib 34. Titanium yog siv nyob rau hauv kev tshawb fawb roj, fais fab nroj tsuag thiab mining thiab ua cov nroj tsuag.

Txheej txheem cej luam

Txuj: ASTM B348

Titanium tuav yog tsim los ntawm kub dov, ib tug txheej txheem uas txo lub cheeb ntawm titanium ingots thaum nce lawv ntev. Txoj kev tsim khoom no tso cai rau kev tswj hwm qhov ntev thiab cov khoom siv kho tshuab, kom ntseeg tau tias muaj kev sib raug zoo thiab siab - cov khoom zoo kawg.

Qhov tshwm sim ntawm ASTM B348 titanium bar yog muaj zog, ruaj, hnav, thiab corrosion heev-resistant, ua rau nws yog ib qho khoom siv zoo heev rau kev lag luam, kev kho mob, thiab kev siv dav hlau.

Peb muab titanium tuav hauv cov qib hauv qab no:

Gr1, Gr2, Gr5, Gr7, thiab Gr5 ELI (Gr23)
Kev cai qhov ntau thiab tsawg tuaj yeem tsim tau raws li cov neeg siv khoom xav tau, thiab kev tshuaj xyuas ultrasonic yog ua tiav ntawm txhua lub bar ua ntej xa khoom kom ntseeg tau zoo sab hauv.

Terminology

Lus txhais

Bar: Ib qho kub dov, forged, lossis txias ua haujlwm ib nrab- cov khoom tiav cov khoom tiav nrog tus ntoo khaub lig- thaj tsam tsawg dua lossis sib npaug li 16 in² (10,323 mm²). Rectangular titanium tuav yuav tsum tsawg dua los yog sib npaug li 10 hauv (254 mm) hauv qhov dav thiab> 0.1875 hauv (4.8 mm) hauv thickness.

Billet: Ib qho khoom semi- tiav, kub dov los yog forged los ntawm ib tug ingot, nrog ib tug ntoo khaub lig-sectional cheeb tsam > 16 in² (10,323 mm²), qhov dav yog tsawg tshaj tsib npaug ntawm thickness.

Kev ua haujlwm, ua tiav, thiab tshwm sim

ASTM B348 titanium bars thiab billets yuav tsum tsis txhob raug mob sab nraud lossis sab hauv tsis zoo uas tuaj yeem cuam tshuam rau lawv txoj kev siv.
Annealed tuav yuav muab nkag rau hauv cov nram qab no tiav:
