304/304L/304H Stainless Steel Pipe

Brief Introduction Of 304/304L/304H stainless steel:
304 stainless steel,European norm 1.4301 is the most common form of stainless steel used around the world, largely due to its excellent corrosion resistance and value.It is an austenite steel.It is not very electrically or thermally conductive and is non-magnetic. It has a higher corrosionresistance than regular steel and is widely used because of the ease in which it is formed into various shapes.It contains between 16 and 24 percent chromium and up to 35 percent nickel, as well as small amounts of carbon and manganese.
304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications. It is also common in buildings, décor, and site furnishings.
304 stainless steel does have one weakness: it is susceptible to corrosion from chloride solutions, or from saline environments like the coast. Chloride ions can create localized areas of corrosion, called "pitting," which can spread beneath protective chromium barriers to compromise internal structures. Solutions with as little as 25 ppm of sodium chloride can begin to have a corrosive effect.
304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious carbide precipitation as a result of welding. 304L can therefore be used "as welded" in severe corrosion environments and it eliminates the need for annealing.
This grade has slightly lower mechanical properties than the standard 304 grade, but it's nonetheless widely used thanks to its versatility. Like Type 304 stainless steel, it's commonly used in beer-brewing and wine-making, but also for purposes beyond the food industry such as in chemical containers, mining and construction. It's ideal for use in metal parts such as nuts and bolts that will be exposed to salt water.
Unlike 304L, Type 304H has a higher carbon content making the steel more suitable for use in applications where elevated temperatures are present. It is an austenitic chromium-nickel steel alloy and the greater carbon content delivers an increased tensile and yield strength.
The material is recommended for use in ASME pressure vessels in working service above 525° C due to the grade's heat resistant properties.
