Product Overview
We supply stabilized stainless steel including 321, 321L, 329, 330, 347 and 347H. Commodities are supplied in plates, round bars and seamless pipes with stable metallographic structure and standardized chemical composition.
Grade performance introduction
321 / 321L: Titanium stabilized steel, low-carbon 321L improves welding corrosion resistance for medium-high temperature pipeline systems.
329: Duplex stainless steel with high strength and good resistance to chloride corrosion for pressure structural parts.
330: High nickel alloy stainless steel, excellent anti-oxidation and anti-carburization capacity for various industrial furnace accessories.
347 / 347H: Niobium stabilized material, 347H with higher carbon owns superior creep strength for high-temperature pressure vessels.
Processing service & quality management
Support cutting, bending, slitting and surface treatment. Strict finished product inspection is implemented with full test reports for customers’ quality verification.
Main application fields
Boiler heat exchange tubes, high-temperature flue pipelines, heat treatment baskets, chemical high-temperature reactors and furnace lining components.
Export packaging
Cover products with rust-proof paper and waterproof film and fix with steel belts. Precision pipes and sheets adopt plywood case packaging to avoid collision damage and rust during long-distance ocean transportation.
