316/316L Stainless Steel Pipe

316 and 316L are molybdenum-containing austenitic stainless steels, with corrosion resistance far superior to 304, especially against chloride ions, seawater, and acidic/alkaline environments. 316: Standard type, high overall strength, suitable for general corrosion protection applications. 316L: Low-carbon version, less prone to intergranular corrosion after welding, more suitable for welded components, pressure vessels, and harsh operating conditions.

SUS316

Characteristics: Mo should be added, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used under harsh conditions. Excellent work hardening (non-magnetic)

Uses: Mainly used in seawater equipment, chemicals, dyes, papermaking. Oxalic acid, fertilizer and other production equipment; Food industry, coastal facilities, ropes, CD rods, bolts, nuts.

316L/SUS316L

Characteristics: As the low C series of 316 steel, in addition to having the same characteristics as 316 steel, its resistance to grain boundary corrosion is excellent.

Use :316 steel use, against grain boundary corrosion fear of special requirements of the product.

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
