Corrosion resistance
The addition of molybdenum makes it perform well in chloride ion environments (such as seawater and chemical media), and its resistance to pitting, crevice corrosion and uniform corrosion is better than 304 stainless steel. Especially in environments with sulfuric acid concentrations below 15% or above 85%, the corrosion resistance is significantly enhanced.
Mechanical properties
Strength and processing: Strength can be improved by cold processing (such as rolling and stretching), but it cannot be hardened by heat treatment.
Tensile strength: Higher than ordinary 304 stainless steel, suitable for scenes with greater pressure.
Applicable scenarios
Industrial environment: Marine engineering, chemical equipment (containing sulfuric acid, phosphoric acid and other media), coastal building exterior materials.
Special working conditions: Papermaking equipment, heat exchangers, piping systems, and industrial scenes that require high corrosion resistance.
Processing characteristics
Weldability: Standard welding methods can be used, and no annealing treatment is required after welding.
High temperature performance: It is resistant to oxidation when used intermittently below 1600℃ or continuously below 1700℃, but long-term use should be avoided in the range of 800-1575℃

Composición del acero inoxidable
El acero es una aleación de hierro y carbono. Los aceros inoxidables son aceros que contienen al menos 10,5% de cromo, menos de 1,2% de carbono y otros elementos de aleación. La resistencia a la corrosión del acero inoxidable y
Las propiedades mecánicas pueden mejorarse aún más añadiendo otros elementos, como níquel, molibdeno, titanio, niobio, manganeso, etc.
