Jiangsu Jiuming 30Cr13 Stainless Steel Plate, Manufacturer for Deep Processing, 30Cr13 Martensitic Stainless Steel Plate
Stainless Steel Sheets Stainless steel sheets feature a smooth surface, high plasticity, toughness, and mechanical strength, and are resistant to corrosion from gases, solutions, and other media. They are an alloy steel that is not prone to rust, but it is not entirely rust-proof. 304 Stainless Steel Sheets 304L stainless steel sheets have significantly lower carbon content than 304. The 304L is superior to 304 in terms of resistance to pitting corrosion at welding points and other treated areas. Chemical Composition 304 Stainless Steel Grade: 0Cr18Ni9 (0Cr19Ni9) 06Cr19Ni9 S30408 Chemical Composition: C: ≤0.08, Si: ≤1.0, Mn: ≤2.0, Cr: 18.0-20.0, Ni: 8.0-10.5, S: ≤0.03, P: ≤0.035, N: ≤0.1. Basic Information Stainless steel sheets are divided into two types based on manufacturing process: hot-rolled and cold-rolled. They are categorized into five types based on the steel's microstructure: Austenitic, Austenitic-Ferritic, Ferritic, Martensitic, and Precipitation Hardening. They are required to withstand corrosion from various substances such as grass, iron, nitric acid, nitric acid-hydrofluoric acid, copper, etc., and are used in industries such as chemicals, food processing, papermaking, oil, nuclear energy, as well as in construction, kitchenware, tableware, vehicles, and various home appliance components.

Stainless Steel Sheets Stainless steel sheets are divided into hot-rolled and cold-rolled types, including thin cold sheets with thicknesses of 0.02-4mm and medium-thick plates with thicknesses of 4.5-100mm. To ensure that the mechanical properties such as yield strength, tensile strength, elongation, and hardness of various stainless steel sheets meet the requirements, the sheets must undergo heat treatment such as annealing, solution treatment, and aging treatment before delivery.

Stainless Steel Sheet Introduction: Stainless steel sheets are categorized into hot-rolled and cold-rolled types, encompassing thin sheets with thicknesses of 0.5-4mm and thick sheets from 4.5-35mm. They are classified into five categories based on the microstructure of the steel: Austenitic, Austenitic-Ferritic, Ferritic, Martensitic, and Precipitation Hardening. These sheets are required to withstand corrosion from grass, iron, nitric acid, nitric-hydrofluoric acid, copper, methyl, ethyl, and various other substances. They are used in industries such as chemical, food, papermaking, oil, atomic energy, as well as in construction, kitchenware, tableware, vehicles, and various home appliance components. To ensure the mechanical properties like yield strength, tensile strength, elongation, and hardness of the stainless steel sheets meet requirements, heat treatments such as annealing, solution treatment, and aging treatment must be conducted before delivery. The corrosion resistance of stainless steel primarily depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal microstructure, with the chromium element playing a major role. Chromium possesses high chemical stability and can form a passivating film on the steel surface, isolating the metal from the outside world and protecting the sheet from oxidation, enhancing its corrosion resistance. Once the passivating film is damaged, the corrosion resistance decreases.

The brand names of Japanese steel (JIS series) are mainly composed of three parts to represent the material, such as: S (Steel) represents steel, F (Ferrum) represents iron; the second part represents different shapes, types, and applications, such as P (Plate) represents plate, T (Tube) represents tube, K (Kogu) represents tool; the third part represents a characteristic number, usually the tensile strength. For example: SS400 - one S represents steel (Steel), the second S represents "structure" (Structure), 400 is the minimum tensile strength of 400MPa, indicating that it is a common structural steel with a tensile strength of 400MPa. SPHC 2. SPHC - The first S stands for Steel, P for Plate, H for Heat, and C for Commercial, indicating general-purpose hot-rolled steel plates and strips.
China Brand Numbers: (1) Cold Rolled Non-Oriented Silicon Steel Strip (Sheet) Representation: DW + 100 times the Iron Loss Value (unit weight iron loss value per unit weight at a magnetic flux peak of 1.5T under a frequency of 50Hz and a sine wave) + 100 times the thickness value. For example, DW470-50 indicates a cold rolled non-oriented silicon steel with an iron loss value of 4.7w/kg and a thickness of 0.5mm, currently represented as 50W470. (2) Cold Rolled Oriented Silicon Steel Strip (Sheet) Representation: DQ + 100 times the Iron Loss Value (unit weight iron loss value per unit weight at a magnetic flux peak of 1.7T under a frequency of 50Hz and a sine wave) + 100 times the thickness value. Sometimes, an "G" added after the iron loss value indicates high magnetic flux. For example, DQ133-30 indicates a cold rolled oriented silicon steel strip (sheet) with an iron loss value of 1.33 and a thickness of 0.3mm, currently represented as 30Q133. (3) Hot Rolled Silicon Steel Sheet Hot rolled silicon steel sheet is represented by DR, divided into low silicon steel (silicon content ≤2.8%) and high silicon steel (silicon content > 2.8%) based on the amount of silicon content. Representation: DR + 100 times the Iron Loss Value (unit weight iron loss value at a magnetic induction intensity of 1.5T during 50Hz repetitive magnetization and sine wave variation) + 100 times the thickness value. For example, DR510-50 indicates a hot rolled silicon steel sheet with an iron loss value of 5.1 and a thickness of 0.5mm. The brand number for hot rolled silicon steel thin plates used in household appliances is represented by JDR + iron loss value + thickness value, such as JDR540-50. Japan Brand Numbers: (1) Cold Rolled Non-Oriented Silicon Steel Strip: Nominal Thickness (expanded 100 times) + Code A + Iron Loss Guarantee Value (100 times the iron loss value at a frequency of 50Hz and magnetic flux density of 1.5T). For example, 50A470 indicates a cold rolled non-oriented silicon steel strip with a thickness of 0.5mm and an iron loss guarantee value of ≤ 4.7. (2) Cold Rolled Oriented Silicon Steel Strip: Nominal Thickness (expanded 100 times) + Code G: indicates general material, P: indicates high orientation material + Iron Loss Guarantee Value (100 times the iron loss value at a frequency of 50Hz and magnetic flux density of 1.7T). For example, 30G130 indicates a cold rolled oriented silicon steel strip with a thickness of 0.3mm and an iron loss guarantee value of ≤1.3.
