Peeled Round Bars / Stainless Steel
AISI 304L
Low Carbon Version of 304
Material Overview
AISI 304L - Low Carbon Version of 304
Material Type
Type: Austenitic, low carbon variant of 304
Key Benefit: Prevents carbide precipitation during welding
Advantages Over 304
- Superior Weldability: No sensitization in heat-affected zones
- Thick Sections: Better for heavy-wall applications
- High-Temperature Welding: Ideal for multi-pass welding
- Corrosion Resistance: Maintains resistance in welded condition
Mechanical Properties
| Tensile Strength: | 485-690 MPa |
| Yield Strength: | 170-310 MPa |
| Hardness: | ~180 HB |
Common Applications
- Pressure vessels and tanks requiring welding
- Welded pipelines and tubing systems
- High-purity processing equipment
- Chemical processing vessels
