Nws yog feem ntau siv rau vuam ntawm carbon steel thiab stainless hlau los yog rau
welding ntawm martensitic thiab ferritic stainless hlau nrog tsis zoo toughness
Nws tseem tuaj yeem siv rau hauv petrochemical, thermal fais fab nroj tsuag thiab
lwm yam lag luam xws li reactor puab phab ntsa surfacing hloov hlau.
Ripple zoo
Vuam 22% Cr-12% Ni stainless hlau (SUS309S)
Los yog stainless hlau nrog carbon steel, tsis tshua muaj alloy steel vuam.
