Stainless Steel 304 Angle is an L-shaped structural profile made of high-quality austenitic stainless steel 304, which has become an ideal choice for industrial, architectural and decorative applications due to its excellent performance and wide applicability. Its core material contains 18% chromium (Cr) and 8% nickel (Ni), giving the product excellent corrosion resistance, can withstand moisture, weak acid and alkali environments and high temperature oxidation (up to 800°C), and at the same time has a non-magnetic, easy to process the characteristics of the product, to support the welding, cutting, bending and other processes.

The right-angled L-shaped cross-section design of the angle is divided into equilateral (e.g. 30 x 30mm) and unequal, with flexible specifications, taking into account the needs of lightweight and high load-bearing. The surface can be polished, brushed and other processes, showing a metallic luster, to meet the aesthetic requirements of decorative projects.

FAQ

Q: How to distinguish between 304 and inferior stainless steel angle?

A: Material testing: stainless steel potion test, 304 should show colourless or reddish.
Marking: regular products have '304' or 'SUS304' steel seal.
Surface quality: high-quality 304 without cracks, burrs, uniform colour.

Q: What are the main application scenarios?

A: Construction: stair handrails, brackets, curtain wall skeleton.
Machinery: equipment frame, reinforcement.
Home: furniture skeleton, decorative strips.
Chemical: corrosion-resistant bracket (need to evaluate media compatibility).

Q: What do I need to be aware of when installing?

A: Cutting: Use special saw blade for stainless steel to avoid carbon steel contamination, which may lead to rust.
Welding: argon arc welding is recommended, and after welding, pickling and passivation are required to restore corrosion resistance.
Fixing: use 304 stainless steel screws to avoid galvanic corrosion.

Q: How do I maintain and clean it?

A: Daily cleaning: neutral detergent + soft cloth to wipe, avoid wire ball scratch.
Rust treatment: Use stainless steel special cleaner or citric acid solution.
Regular inspection: check for pitting in humid or high salt environment.

Q: What are the factors that influence price?

A: Nickel price fluctuation: 304 contains nickel, international nickel price affects the cost.
Size and thickness: the thicker and wider the price is higher.
Surface treatment: polished is more expensive than gross.

Q: How to choose with 316 stainless steel angle?

A: 304: suitable for general environment, cost-effective.
316: contains molybdenum, resistant to chloride corrosion, such as coastal, chemical, but the price is 30% ~ 50% higher.
