    ASME SA249 Stainless Steel Welded Pipe , SS Welded Pipe For Falling Film Evaporators

    ASME SA249 ASTM A249 TP304 OD4'' X 1.5MM Welded Stainless Steel Tube for Falling Film Evaporators


    AISI 304 welded stainless steel tube is the most common material in stainless steel. Because SS 304 contains 18% chromium (Cr) and 8% nickel (Ni), it is also known as 18/8 stainless steel. SS304 has good processability, weldability, corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, and no heat treatment hardening. SS304 is widely used in the industrial and furniture decoration industry and the food and medical industry.


    The reason why 304 grade stainless steel has excellent corrosion resistance in the atmosphere is due to the formation of a chromium passivation film on its surface. But when SS304 is in a warm chloride environment, the corrosion is even faster than non-alloy mild steel.
