Type304 often refers to as 18-8(18%chromium,8%nickel).T304 is the basic stainless alloy mostly commonly commomly untilized for wire cloth weaving .it with stands outdoor exposure withot rusting and resists oxidation at an elevated temperature up to 1400 degrees fahrenheit. type 304L is very similar to T-304, the difference being the reduced carbon content for better weaving and secondary welding characteristics

Type 316 :stabilezed by the addition of 2%molybdenum ,T-316is an 18-8alloy .type 316 has better resistance to pitting corrosion than the other chromium-nickel stainless steel where brines ,sulfur-bearing water or halogen salts ,such as chlorides are present.type 316L :Type 316 is very similar to T-316 ,the difference being the reduced carbon content for better wire cloth weaving and secondary welding characteristics
