405 stainless steel 
 Name: ferritic stainless steel 
 Standard: AISI, ASTM, 
 Type: 405 
 UNS Number: S40500 
 ● 405 steel properties and applications: 
 405 is equivalent to China's 0Cr13Al stainless steel cooling from high temperature to produce a significant hardening. 405 stainless steel for turbine materials, quenching parts, composite steel. 
 405 stainless steel tube annealed / (° C) :780-830 fast-cooling or slow
