Characteristics:
Shiny surface condition excellent workability
Applications:
It generally used in braiding the hose for bathing product and machinery. With it good flexibility,resistant to high temperature and resistant to corrosion,it used widely in many industries.
Type 304 often refers to as "18-8" (18% chromium, 8% nickel ). T-304 is the basic stainless alloy mostly commonly utilized for wire cloth weaving. It withstands outdoor exposure without rusting and resists oxidation at an elevated temperature up to 1400 Degrees Fahrenheit. Type 304 L is very similar to T-304, the difference being the reduced carbon content for better weaving and secondary welding characteristics.
Type 316: Stabilized by the addition of 2% molybdenum, T-316 is an "18-8" alloy. Type 316 has better resistance to pitting corrosion than the other chromium-nickel stainless steels where brines, sulfur-bearing water or halogen salts, such as chlorides are present. Type 316 L: Type 316 L is very similar to T-316, the difference being the reduced carbon content for better wire cloth weaving and secondary welding characteristics.
