| Property | Tensile Strength (MPa) | Yield Strength 0.2% (MPa) | Elongation (%) | Hardness (HB / HRB) |
|---|---|---|---|---|
| SS 304 Annealed | 515 min | 205 min | 40% min | 201 HB max |
| SS 304L Annealed | 485 min | 170 min | 40% min | 201 HB max |
Hygienic WFI piping and tank flanges resistant to organic acids and sanitizing agents.
Low-to-medium temperature nitric acid and general chemical transport.
Structural forging rings, pressure vessel nozzles, and high-strength industrial flanges.
SS 304L has a lower carbon content (<=0.03%) which prevents intergranular chromium carbide precipitation during welding, making 304L superior for heavy welded flange assemblies.
We manufacture ASME B16.5 SS 304 flanges in Class 150, 300, 600, 900, 1500, and 2500.
Yes, every batch is supplied with an EN 10204 3.1 Mill Test Certificate including PMI chemistry reports and heat number traceability.
Delivering precision-engineered flanges, pipes, and forged steel components designed for strength, durability, and performance in critical high-pressure industrial applications.
