Feature :
--Add Ti in 304 steel, so corrosivity is fine when it is brilliant to resist; --Intensity of high temperature and high temperature resist oxygen quality finely; --With high costs, processability is inferior to 304.
The use:
--Aviation machine part, and boiler vapour make blast pipe; --The utensil which the chemical industry, hot permutater,etc. used under the high temperature.
