FAQ
Stainless steel 304 pipe's weight is calculated using one formula which is P=t(D−t)×C. Where: t = Thickness (mm or inches) D = Outer Diameter (inches) C = Specific weight of 304 stainless steel (0.287lbs/in3)
304 stainless steel is good quality. It has excellent anti-corrosive property, good formability and good strength hence it is a popular and widely used stainless steel grade. 304 is indeed a very capable and often more economical choice for a wide array of applications.
The primary difference depends on their chemical composition. 316 stainless steel includes molybdenum roughly 2% which boosts its corrosion resistance especially against chlorides and acids compared to 304. Visually they appear very similar.
304 stainless steel contains about 18% chromium and 8% of nickel. It is popularly known as 18/8 stainless steel.
304L has less carbon and more 0.03% for enhanced weldability. 304H has maximum carbon content 0.04 - 0.10% for higher strength at elevated temperatures including chemical resistance up to 925°C.
Designed for use demanding great strength under harsh temperature, a 304H pipe is a high carbon variant of 304 stainless steel.
The main difference is the carbon content. 304L's lower carbon level improves weldability and reduces the risk of sensitization, while 304 offers slightly higher strength but is more exposed to hostile environments during soldering.
Suitable for utensils like sinks and saucepans, stainless steel 304L is a low carbon austenitic grade with great weldability and uniformity for deep drawing process manufacture.
We offer a comprehensive range of 304 stainless steel pipes and tubes. We may cut them to your precise proportions or provide them in conventional sizes. Purchasing directly from us makes getting what you need quite simple.
