304 Stainless Steel Angle

Procurement guide for 304 equal and unequal stainless angle covering route, leg dimensions, thickness, straightness, twist, finish, fabrication and traceability.

03Grade-product

Specifications and dimensions

State equal or unequal legs, leg dimensions × thickness, root radius, length and mass/section tolerance.
Define hot-rolled, laser-welded, bent or fabricated route; these products can have different corner geometry and properties.
Specify straightness, twist, squareness, cut length, end preparation, surface finish and hole pattern where required.

Standards and supply condition

ASTM A276/A276M for applicable stainless bars and shapes
ASTM A484/A484M general requirements or the ordered formed/fabricated specification

Manufacturing and processing

Angles may be hot rolled, cold formed from strip, laser welded or fabricated; the route must match the ordered standard and design basis.
Cutting, drilling, welding, pickling/passivation and finishing are coordinated with connection drawings and corrosion requirements.

Typical applications

Equipment frames, platforms, brackets and supports
Architectural trim, façade and interior framing
Food, chemical and marine fabrication after design review

Quality and acceptance controls

Verify grade, product route, heat treatment, chemistry and mechanical results against the ordered standard.
Measure legs, thickness, angle, root radius, straightness, twist, length and mass.
Inspect surface, edge cracking, welds where applicable, cut ends and hole position against drawings.
Confirm heat/lot traceability through cutting and fabrication, plus clean packing to prevent iron contamination.

Include in your RFQ

Exact grade or alloy designation and governing product-standard edition
Product form, manufacturing route and ordered delivery condition or temper
Nominal dimensions, tolerances, length/coil geometry and quantity
Surface finish, edge/end condition, straightness/flatness and permitted defects
Fabrication, forming, machining, welding and heat-treatment requirements
Mechanical, corrosion, coating or application-specific acceptance tests
Inspection document, heat/lot traceability, marking and third-party inspection
Packing, preservation, destination, Incoterms and required delivery date

Selection limits

304 designation does not define bar/strip/angle dimensions, condition, finish, tolerance or acceptance; the product standard and order do.
A bent or laser-welded angle is not automatically dimensionally or structurally equivalent to a hot-rolled shape.
