Electropolished raws li ASTM B912
Peb ua eddy tam sim no testing, uas tuaj yeem nrhiav cov kab mob me hauv high-temperature bolts uas cov milling cutters zoo tib yam tsis tuaj yeem pom.
Peb ua haujlwm ib kab tsim khoom tsim kho nrog cov yam ntxwv:
Lub peev xwm tsim xyoo 8 lab pieces
Laser-etched marking (kev txheeb xyuas qib tas mus li)
MTC siv blockchain qhia tag nrho cov txheej txheem los ntawm melting mus txog xa khoom
Peb lub tsev khaws khoom muaj 3M+ SS 321 hexagonal bolts hauv ntau thiab tsawg M8-M24, txhua tus ua raws li ASME B18.2.1 cov qauv, thiab muab cov ntaub ntawv tseem ceeb tshiab hauv real time.
