Top-quality 316 stainless steel tubes from China manufacturer. Enhanced corrosion resistance, molybdenum-added alloy, suitable for marine, chemical, and industrial use. Custom sizes and shapes available.
2507 contains a higher level of chromium, molybdenum, and nitrogen than standard duplex grades, offering superior corrosion resistance and mechanical strength in harsh environments.
It’s used in seawater equipment, heat exchangers, pressure vessels, desalination plants, and chemical/petrochemical industries due to its extreme corrosion resistance and durability.
Yes. We offer complete OEM customization, including non-standard wall thicknesses, shapes, and pre-cut lengths based on your project drawings.
Yes. We manufacture both types to suit different pressure and cost requirements.
Each order is delivered with Mill Test Certificates (EN10204 3.1/3.2). We also support SGS, TUV, BV, ABS, and LR third-party inspections upon request.
While 2507 performs excellently in corrosive environments, it’s generally recommended for use in temperatures below 600°F (316°C) to avoid embrittlement.
