1. Introduction to 13mnnimor steel plate.
13mnnimor steel plate is a high-strength, high-toughness, corrosion-resistant alloy structural steel, which is widely used in petrochemical, electric power, shipbuilding, construction and other fields.
Second, the chemical composition of 13mnnimor steel plate.
3. Mechanical properties of 13mnnimor steel plate.
Fourth, 13mnnimor steel plate manufacturing process.
Smelting: Electric furnace + external refining process is adopted to ensure the chemical composition and physical properties of steel.
Continuous casting: The billet is produced through continuous casting technology to ensure the internal quality and surface quality of the billet.
Rolling: Hot continuous rolling or controlled rolling and controlled cooling process are used to ensure the uniformity of the structure and properties of the steel plate.
Heat treatment: normalizing + tempering heat treatment is carried out to eliminate internal stress and improve the mechanical properties and corrosion resistance of the steel plate.
Inspection: Chemical composition, mechanical properties, size and surface quality inspection are carried out on each batch of steel plates.
Packaging: Adopt moisture-proof, rust-proof, shockproof and other measures for packaging to ensure that the steel plate is intact during transportation and storage.
