QIDA METAL · PRODUCT PROCUREMENT GUIDE
304L Stainless Steel Angle
For equipment supports, architectural metalwork and corrosion-resistant connections. Specify hot rolled, welded or bent manufacture, material standard, corner geometry and visible faces together.
| Procurement Item | Details |
|---|---|
| Applicable Standard | ASTM A276/A276M / 304L (bars and shapes) |
| Product Category | Steel Sections & Bars / Angles |
| Dimensions & Quantity | The sizes below are enquiry references. Available combinations, quantities and delivery times are subject to written quotation. |
| Documentation | Specify heat/batch inspection documents, standard edition, traceability and project certification in your enquiry. Documents are subject to confirmation of actual availability. |
01 / Product Features & Selection
- Confirm low-carbon 304L and the shape standard separately for welded-service material selection.
- Agree finish and outer radii by sample / drawing for visible-face assemblies.
- Specify contamination prevention, post-weld cleaning and separated packaging to protect corrosion-resistant surfaces.
02 / Specifications, Dimensions & Ordering Options
These dimensions help define your purchase requirement; they do not imply that every combination is in stock. Specify tolerances, quantity, delivery condition and destination port. Submit drawings for special sizes.
| Parameter | Specification / Enquiry Range | Points to Confirm |
|---|---|---|
| Equal Leg Dimensions / mm | 20×20, 25×25, 30×30, 40×40, 50×50, 60×60, 75×75, 80×80, 100×100 | Confirm leg thickness and corners for the actual series. |
| Unequal Leg Dimensions / mm | Submit a×b×t drawings. | Hot rolling, laser welding and plate bending are not automatically equivalent. |
| Thickness / mm | 3, 4, 5, 6, 8, 10, 12 | Distinguish nominal thickness from minimum thickness after polishing. |
| Length / m | 6 or fabrication cut lengths | Identify drilled, mitred and welded parts by drawing number. |
| Standard / Finish | Applicable A276 / A484 requirements; pickled or agreed brushed / polished finish | Confirm parent material, consumables and procedures for welded assemblies separately. |
03 / Standard Chemical Composition
ASTM A276/A276M / 304L (bars and shapes). Values are mass percentages (%). Maximum limits are shown by ≤, minimum limits by ≥; ranges are specification limits and Fe is the balance. These are not measured results for a current delivery heat.
| Element / Indicator | Requirement or Range |
|---|---|
| C | ≤0.030 |
| Si | ≤1.00 |
| Mn | ≤2.00 |
| P | ≤0.045 |
| S | ≤0.030 |
| Cr | 18.0–20.0 |
| Ni | 8.0–12.0 |
| Fe | Balance |
Common A276 304L bar / shape composition, mass %. Confirm product standards separately for laser-welded, hot rolled and cold-drawn routes. Do not substitute A240 plate or A312 pipe chemistry.
04 / Mechanical Properties & Application Limits
| Thickness / Material Condition | Yield Strength Re / Rp0.2 (MPa) | Tensile Strength Rm (MPa) | Elongation After Fracture A (%) |
|---|---|---|---|
| Annealed reference; confirm dimensions and specimens | Rp0.2 ≥170 | ≥485 | ≥40 |
Strength in MPa, A in %. Accept cold-worked and built-up shapes against the actual product standard. Annealed round-bar data does not establish the structural capacity of a welded assembly.
05 / Inspection, Processing & Quality Checks
- Verify heat number, 304L chemistry and manufacturing route; magnetism or brightness alone does not identify grade.
- Check leg thickness, angle, radii, straightness, twist and surface defects.
- Specify weld cleaning and pickling / passivation; avoid shared carbon-steel abrasives.
- Assess 316L or other materials for coastal / high-chloride service together with maintenance intervals.
06 / Export Packaging for This Product
| Stage | Recommended Arrangement | Key Considerations |
|---|---|---|
| Section-Separated Bundles | Identify section designation, steel grade, length and heat number separately. | Keep different grades and delivery conditions in separate bundles. |
| Supports & Corner Protection | Protect flanges, leg edges and machined faces; support long sections at multiple points. | Prevent handling twist, local damage and permanent bending. |
| Loading Checks | Plan loading around cut length, bundle weight, forklift points and container-door clearance. | Assess container type and handling arrangements in advance for long or heavy loads. |
Before shipment, cross-check product, grade, heat number, size, piece count, net weight and gross weight against the packing list. Match labels to inspection documents. For solid-wood pallets, dunnage or crates, check destination-country rules; wood subject to ISPM 15 must be treated and marked by an approved provider. Load dry cargo and arrange supports, blocking and securing according to weight and centre of gravity.
07 / How Qida Supports Your Procurement
| Procurement Stage | Qida Coordination | Information for the Buyer |
|---|---|---|
| Requirement Review | Review application, standards, material condition, drawings and acceptance items. | A checkable specification list helps reduce language and unit-conversion errors. |
| Order Confirmation | Confirm material, processing, inspection, packaging, delivery milestones and cost responsibilities item by item. | A clear written quotation and mutually agreed purchase requirements. |
| Delivery Coordination | Coordinate production / sourcing progress, labels, packing lists and shipping documents. | Check dimensions, quantities and heat/batch correspondence at agreed milestones. |
| After-Sales Follow-Up | Review issues using order number, heat number, arrival photographs and test records. | A defined issue description and documented resolution communications. |
Qida focuses on clear specifications, material requirement checks and delivery coordination. Include cutting, cut-to-length, surface treatment, third-party inspection and certificate requirements in your enquiry so that the achievable scope can be agreed before order placement.

Technical Sources & Ordering Notes
This selection and enquiry guide is compiled from the primary public sources below. Values are not an inspection certificate for a delivery batch and do not imply a supply or authorization relationship with the source publishers. The agreed order governs standard edition, product form, thickness range, specimen and delivery condition. Similar grades are not automatically equivalent. Confirm project certification and inspection documents before ordering.
