304L Stainless Steel Tube Pipe

Alloys 304 (S30400) and 304L (S30403) stainless steels are variations of the 18 percent chromium – 8 percent nickel austenitic alloy, the most familiar and most frequently used alloy in the stainless steel family.


High strength, excellent corrosion resistance and minimized carbon content make Alloy 304 and 304L Stainless Steels useful for applications where welding is required. Uses include architectural mouldings and trim, welded components of chemical, textile, paper, pharmaceutical and chemical industry processing equipment.


Other advantages are its resistance to oxidation, excellent formability, ease of fabrication and cleaning, excellent strength to weight ratio and good toughness at cryogenic temperatures.


For severely corrosive environments, the lower content of Type 304L is preferred because of its greater immunity to intergranular corrosion.

Properties of 304 stainless steel

also known as 18/8 ,is a kind of strong commonality and most widely used chrome - nickel stainless steel.

As a kind of widely used steel, it has good corrosion resistance, heat resistance, strength and mechanical properties at low temperature. Hot work-ability such as punching, bending is excellent.No heat treatment hardening phenomenon . If it is in industrial pollution area, you will need to clean in time to avoid the corrosion.
