SS 304 is standardized internationally under the following cross-references, which buyers can use to match specifications across different sourcing regions:
Mechanical properties for SS 304 pipe meet the following minimums:
SS 304's oxidation resistance holds up well under thermal loading: the material withstands intermittent thermal exposure up to 870°C and continuous service up to 925°C without degrading. This, combined with the grade's retained ductility and impact strength at very low temperatures, gives SS 304 pipe a usable service range spanning cryogenic to moderately high-temperature applications.
Every SS 304 pipe order from Siddhgiri Overseas is dimensionally checked before dispatch, and Mill Test Certificates (MTC) are issued documenting the material's properties for project records and compliance requirements.
SS 304 pipe from Siddhgiri Overseas is manufactured across a very wide sizing range to serve everything from light architectural trim to heavy industrial process lines:
Both seamless and welded/ERW construction are available across this size range, allowing the construction type to be matched to the application rather than forcing a single method across every job.
Surface finish is specified separately from size and schedule. Available finishes include:
SS 304 pipe's balance of corrosion resistance, formability, and weldability makes it suitable across a broad range of industries:
For chloride-heavy or marine environments outside SS 304's comfort zone, SS 316/316L is the better-suited grade; for projects involving heavy or repeated welding, SS 304L reduces the risk of carbide precipitation at the weld.
Siddhgiri Overseas is ISO certified for quality, occupational health & safety and environment management, and holds the import and export certification required to supply stainless steel pipe and tube to customers worldwide. Certificate copies are available on request for buyers who need them for their own compliance records.
SS 304L is a low-carbon version of SS 304, developed specifically to reduce the risk of carbide precipitation during heavy or repeated welding. If a project involves extensive field welding, 304L is generally the safer choice; for general-purpose use, standard SS 304 performs the same core role.
SS 316 adds molybdenum to the composition, which gives it significantly better resistance to chlorides and marine environments than SS 304. SS 304 is the right choice for general industrial, architectural, and food-grade use; SS 316/316L is better suited to coastal, marine, or heavy-chloride process environments.
Yes. SS 304 is widely used in food and beverage processing lines, and with a 2B or mirror-polished (#8) finish it is a standard material choice for sanitary and food-processing equipment.
SS 304 is an austenitic stainless steel, and in its annealed condition it is generally non-magnetic to weakly magnetic. Cold working during forming can increase magnetic response slightly, which is normal for this grade family.
SS 304 withstands intermittent thermal exposure up to 870°C and continuous service up to 925°C without degrading, making it suitable for applications like automotive exhaust systems that see cyclical high-temperature exposure.
Yes, Siddhgiri Overseas manufactures SS 304 pipe in both seamless and welded/ERW construction across the full size range, so the construction type can be matched to the application and budget.
SS 304 pipe is available from 1/8" NB (15.88mm OD) thin-wall sizes up to 48" NB (1219mm OD) heavy structural sizes, spanning Schedule 5S/10S through Schedule 160, covering architectural, structural, and industrial process applications.
Yes. Every SS 304 pipe order is dimensionally checked before dispatch, and Mill Test Certificates (MTC) documenting the material's properties are issued with the shipment.
