Corrosion resistance
TP304 is an austenitic stainless steel containing 18%-20% chromium and 8%-11% nickel. It exhibits excellent corrosion resistance in oxidizing environments, especially for common acid and alkali media such as dilute sulfuric acid and dilute nitric acid. Its intergranular corrosion resistance is comparable to that of Super304H, but σ phase and carbide precipitation may occur after high-temperature aging, resulting in a decrease in thermal strength.
Mechanical properties
High temperature performance: Long-term use temperature can reach 650℃, and oxidation resistance temperature can reach 850℃.
Processing performance: Excellent cold deformation ability, supporting bending, cutting and sizing processing.
Mechanical properties: Tensile strength, yield strength and elongation all meet industry standards, and the elongation can reach more than 35% after heat treatment.
Application scenarios
Chemical/petroleum: Used in heat exchangers, pipelines and other equipment, corrosion-resistant and pressure-resistant.
Food processing: The surface is smooth and easy to clean, suitable for food pipelines such as dairy products and meat processing.
Medical equipment: manufacturing surgical instruments, implant housings and piping systems with good biocompatibility.
Architectural decoration: used for high-end building handrails, door and window frames, etc., with both corrosion resistance and aesthetics.
Production process
The organization properties are optimized through hot rolling perforation, cold rolling forming and solution heat treatment, and the specifications cover pipes with an outer diameter of 6-377mm and a wall thickness of 1.0-20mm.

Composição do aço inoxidável
O aço é uma liga de ferro e carbono. Os aços inoxidáveis são aços que contêm pelo menos 10,5% de crómio, menos de 1,2% de carbono e outros elementos de liga. A resistência à corrosão do aço inoxidável e
As propriedades mecânicas podem ser melhoradas pela adição de outros elementos, como o níquel, o molibdénio, o titânio, o nióbio, o manganês, etc.
