2、 Physical and mechanical properties

Source of project parameters

Density 7.93 g/cm ³

Melting point 1250-1400 ℃

Tensile strength in solid solution state ≥ 480 MPa, can reach 520-1035 MPa after cold processing

Yield strength in solid solution state ≥ 170 MPa, after cold processing ≥ 263.8 MPa

Elongation rate ≥ 40% (solid solution state), slightly decreased after cold processing

High temperature stability: Maintain stability below 800 ℃, short-term tolerance to 1000-1200 ℃

3、 Typical application areas

Chemical and energy: reaction vessels, petroleum pipelines, valves (resistant to weak acid/alkali media).

Food and medical: food processing equipment, surgical instruments (non-magnetic and in compliance with hygiene standards).

Architectural decoration: curtain walls, handrails, door and window frames (both aesthetically pleasing and weather resistant).

Automobile manufacturing: exhaust system, decorative parts (resistant to high temperature and corrosion).

4、 Standard and brand

International standards: ASTM A240 (sheet metal), EN 10088-2 (European standard), JIS SUS304 (Japanese standard).

Chinese brand: 06Cr19Ni10 (new national standard), old brand 0Cr18Ni9 57.

5、 Selection and Precautions

Low carbon version: 304L (C ≤ 0.03%) is suitable for high intergranular corrosion resistance scenarios.

Surface treatment: Available in 2B (matte), BA (glossy) and other processes to meet decorative needs.

Environmental restrictions: Avoid long-term exposure to chlorides (such as seawater) to prevent the risk of pitting corrosion.

S30400 steel plate is widely used in both industrial and civilian fields due to its corrosion resistance, processing flexibility, and high temperature stability. When selecting, it is necessary to optimize the matching based on environmental and process requirements.
