SUH409L Stainless Steel Coil Strip Price Per kg (latest 2026)

As of 2026, the global stainless steel market remains volatile, driven by energy transition policies, fluctuations in raw material costs, and shifts in the automotive manufacturing landscape. For procurement managers, understanding the price of SUH409L stainless steel involves more than just tracking the "per-kilogram" quote; it requires strategic timing of purchases. By mid-2026, prices for SUH409L stainless steel coils and strips typically ranged from $1.10 to $1.55 per kilogram (FOB China/Asia), depending on thickness, surface finish, and order volume.

 

What is the price of SUH409L stainless steel coil in 2026?

As of early June 2026, SUH409L (S40903/00Cr11Ti) cold-rolled coil/strip FOB China prices stand at USD 1.15–1.35 per kg (USD 1,150–1,350/ton) for standard 2B finish, 0.5–2.0 mm thickness, 1000/1219 mm width, with prime automotive-grade material at USD 1.20–1.50 per kg; thin gauges (0.4–1.0 mm) command a USD 0.05–0.10/kg premium, while 1219 mm width adds USD 0.03–0.05/kg, and BA surface carries a USD 0.05/kg uplift over 2B, based on FOB Shanghai/Ningbo terms with 1-ton minimum order.

According to market trends for 400-series stainless steel coils in China and supplier quotations in 2026, the indicative price range for SUH409L stainless steel coils is as follows:

SUH409L Stainless Steel Coil Price Trend(2026)

Price Trend Analysis (2026 January to June):

SUH409L 2B Finish: Increased by 12.8% from $1,083/ton to $1,222/ton

SUH409L No.1 Finish: Rose by 13.3% from $1,042/ton to $1,181/ton

Average monthly price increase: ~1.9-2.2% per month

 

What is the difference between SUH409L and SUH409?

The main difference is that SUH409L is a low-carbon version of standard SUH409.

Carbon Content: The maximum carbon content of standard SUH409 is 0.08%, while the maximum carbon content of SUH409L is limited to 0.03%.

Weldability: SUH409L is specifically designed for superior weldability. The lower carbon content prevents the formation of chromium carbide (a type of sensitization defect) in the weld area, thus reducing the risk of post-weld intergranular corrosion.

 

How to calculate the weight of SUH409L Coils?

Where:
OD = outer diameter (mm)
ID = inner diameter (mm)
Width = coil width (mm)
0.00785 = density conversion factor for steel

 

Applications of SUH409L Stainless Steel Coil

Automotive exhaust systems: manifolds, front exhaust pipes, and catalytic converter housings.

Heat exchangers: Industrial furnace components requiring oxidation resistance up to 650°C.

Agricultural equipment: Components exposed to mildly corrosive environments, where aesthetics are less critical but durability is paramount.

Household appliances: High-end oven liners and heating element supports.

 

How to verify the quality of SUH409L during the procurement process?

To verify the quality of SUH409L during procurement, buyers should check the chemical composition (C ≤0.03%, Cr 10.5–11.75%, Ni ≤0.5%, Ti ≥6×(C+N)), confirm mechanical properties (tensile 350–450 MPa, yield ≥205 MPa, elongation ≥20%) via Mill Test Certificates (EN 10204 3.1), inspect surface finish for scratches, pits, or oxidation, measure thickness and width tolerances (±0.02–0.05 mm), and ensure batch traceability, as deviations can reduce corrosion resistance and weldability in automotive or industrial applications.
