Hauv stainless hlau, peb muaj austenitic steel, martensitic steel, ferritic steel, Hastelloy, Monel, duplex, super duplex, thiab ntau ntxiv. Peb kuj tseem muab cov hlau phaj ntawm titanium thiab lwm yam hlau hlau alloys muaj zog. Cov hlau phaj no muaj ntau ntau ntawm toughness thiab hardness. Lawv muaj lub zog tensile ntau dua thiab muaj zog dua tawm los. Lawv kuj yog heev malleable thiab ductile nyob rau hauv cov xwm. Qhov no yog vim li cas vim li cas peb thiaj li muaj qhov sib txawv ntawm cov hlau phaj rau txhua yam kev lag luam thiab cov tshuab ua haujlwm.
Lawv kuj tseem tiv taus ntau hom kev xeb xws li oxidation, txo qis, thiab crevice corrosion. Lawv tuaj yeem tiv taus kom ya raws thiab siab dua huab cua kuj tseem tuaj yeem tiv taus cov cua kub siab thiab lwm yam gases uas tej zaum yuav muaj kuab lom heev. Lawv tuaj yeem tiv taus ntau hom roj thiab lwm yam tshuaj. Lawv tuaj yeem tiv taus qhov corrosion vim cua sov ntawm qhov kub siab heev. Lawv yog qhov tsim nyog tshaj plaws rau kev siv hauv marine daim ntawv thov vim lawv tuaj yeem tiv taus dej hiav txwv tau yooj yim.
Cov hlau phaj no kuj yog weldable nyob rau hauv ib txwm theem raws li lawv yog welded thiab machined nyob rau hauv lub annealed tej yam kev mob. Lawv kuj tsis tas yuav preheating thiab yooj yim rau welded, machined thiab tsim. Tuam Tshoj koom ua ke hlau thiab hlau txwv S890Q steel daim hlau yog ua los ntawm cov khoom zoo zoo raw khoom thiab tseem muaj kev tshuaj xyuas thib peb kom ntseeg tau tias kev ua haujlwm raug. Peb tab tom muab cov kev pabcuam zoo tshaj plaws rau kev txaus siab ntawm peb cov neeg siv khoom txaus siab. Peb ib txwm sim muab kev pabcuam zoo thiab nrawm rau peb cov neeg siv khoom.
