Stainless Steel 304L Tubing
Stainless steel 304L tubing is a low-carbon variant of the standard 304 grade, also referred to as TP304L or 304L stainless steel tube. The 0.03% reduction in carbon content makes it highly resistant to sensitisation during welding. It is widely used across food processing, pharmaceuticals, oil and gas, and chemical industries where corrosion resistance and weld integrity are non-negotiable.
Stainless Steel 304L Tubing Price
Stainless steel 304L tubing is priced based on tubing form, size, finish, and order quantity. Understanding the key pricing parameters helps in accurate sourcing and budgeting.
Approximate price range:
In India, the stainless steel 304L tubing price per kg and per foot both vary. It generally costs between INR 220 and 320 per kg. Seamless tubes are more expensive, depending on their diameter and wall thickness.
Cost per foot (approx.):
A standard 1-inch 304L seamless tube (Schedule 40) costs per foot. Larger diameters and heavier wall schedules increase the cost proportionally. The stainless steel 304L tubing price per kg and per foot both vary by order size and finish specification.
Factors affecting the price:
Raw material cost, surface finish (polished vs. mill finish), tubing type (seamless vs. welded), and order volume are the 4 primary factors that determine the final stainless steel 304L tube price. Bulk orders reduce the per-kg rate.

How To Choose The Right Stainless Steel 304L Tubing
Choosing the right 304L stainless steel tube supplier directly affects material quality, project timelines, and long-term performance. Evaluate any supplier across these 6 criteria before placing an order.
Evaluate the manufacturer's technical expertise:
A qualified manufacturer maintains detailed knowledge of low-carbon austenitic grades, including TP304L. Request material test reports (MTRs), mill certifications, and grade-specific datasheets before confirming any order.
Check grade availability and product range:
A reliable 304L stainless steel tube supplier maintains a ready inventory across seamless, welded, ERW, and instrumentation tube forms. Avoid suppliers who source only on demand; lead time risk is high.
Verify quality certifications and testing capabilities:
Confirm ISO 9001 certification and the ability to produce NDT reports, hydrostatic test results, and third-party inspection documents from bodies such as SGS or Bureau Veritas.
Examine the strength of raw material sourcing:
SS 304L tubing should come from certified mills. Request mill traceability documents and verify that raw material procurement complies with ASTM A213, A269, or equivalent international standards.
Assess customisation capabilities:
If the project requires non-standard OD, special wall thickness, or specific finish grades, confirm that the manufacturer supports custom fabrication within standard lead times.
Review delivery timelines and supply capacity:
Confirm dispatch capacity, warehouse location, and the supplier's ability to handle urgent or large-volume orders. On-time delivery is a direct indicator of operational reliability.
Stainless steel 304L tubing is a low-carbon variant of the standard 304 grade, also referred to as TP304L or 304L stainless steel tube. The 0.03% reduction in carbon content makes it highly resistant to sensitisation during welding. It is widely used across food processing, pharmaceuticals, oil and gas, and chemical industries where corrosion resistance and weld integrity are non-negotiable.
Stainless Steel 304L Tubing Price
Stainless steel 304L tubing is priced based on tubing form, size, finish, and order quantity. Understanding the key pricing parameters helps in accurate sourcing and budgeting.
Approximate price range:
In India, the stainless steel 304L tubing price per kg and per foot both vary. It generally costs between INR 220 and 320 per kg. Seamless tubes are more expensive, depending on their diameter and wall thickness.
Cost per foot (approx.):
A standard 1-inch 304L seamless tube (Schedule 40) costs per foot. Larger diameters and heavier wall schedules increase the cost proportionally. The stainless steel 304L tubing price per kg and per foot both vary by order size and finish specification.
Factors affecting the price:
Raw material cost, surface finish (polished vs. mill finish), tubing type (seamless vs. welded), and order volume are the 4 primary factors that determine the final stainless steel 304L tube price. Bulk orders reduce the per-kg rate.

How To Choose The Right Stainless Steel 304L Tubing
Choosing the right 304L stainless steel tube supplier directly affects material quality, project timelines, and long-term performance. Evaluate any supplier across these 6 criteria before placing an order.
Evaluate the manufacturer's technical expertise:
A qualified manufacturer maintains detailed knowledge of low-carbon austenitic grades, including TP304L. Request material test reports (MTRs), mill certifications, and grade-specific datasheets before confirming any order.
Check grade availability and product range:
A reliable 304L stainless steel tube supplier maintains a ready inventory across seamless, welded, ERW, and instrumentation tube forms. Avoid suppliers who source only on demand; lead time risk is high.
Verify quality certifications and testing capabilities:
Confirm ISO 9001 certification and the ability to produce NDT reports, hydrostatic test results, and third-party inspection documents from bodies such as SGS or Bureau Veritas.
Examine the strength of raw material sourcing:
SS 304L tubing should come from certified mills. Request mill traceability documents and verify that raw material procurement complies with ASTM A213, A269, or equivalent international standards.
Assess customisation capabilities:
If the project requires non-standard OD, special wall thickness, or specific finish grades, confirm that the manufacturer supports custom fabrication within standard lead times.
Review delivery timelines and supply capacity:
Confirm dispatch capacity, warehouse location, and the supplier's ability to handle urgent or large-volume orders. On-time delivery is a direct indicator of operational reliability.
