Introduction to SA240 304 Material Sheets

SA240 304 material sheets are versatile austenitic stainless steel products widely utilized in industries such as chemical processing, food manufacturing, and construction. These sheets, compliant with ASME SA240 standards, provide outstanding corrosion resistance, formability, and strength, making them a staple for various applications.

Gangsteel, a premier manufacturer and exporter based in China, offers top-tier SA240 304 sheets tailored for global markets. As a reliable ASME SA240 stainless steel plate supplier, Gangsteel ensures precision engineering and competitive pricing. This article delves into the features, applications, and advantages of SA240 304 material sheets, incorporating tables for enhanced clarity.

What is SA240 304 Material?

SA240 304 is an austenitic stainless steel grade featuring 18–20% chromium and 8–10.5% nickel, which contribute to its superior corrosion resistance and durability. This material is non-magnetic in the annealed state and can be hardened through cold working. Equivalent materials include UNS S30400, EN 1.4301, and JIS SUS304, facilitating international use. Gangsteel’s SA240 Gr 304 sheets are produced under strict ASTM A240 stainless plate guidelines, ensuring high performance in diverse environments.

 

Chemical Composition of SA240 304

The chemical composition of SA240 304 is defined by ASME SA240 to guarantee optimal corrosion resistance and mechanical integrity. The table below outlines the key elements:

Element

SA240 304 Composition

Purpose

Carbon (C)

≤ 0.08%

Allows for strength while maintaining weldability.

Chromium (Cr)

18.0–20.0%

Enhances corrosion and oxidation resistance.

Nickel (Ni)

8.0–10.5%

Improves ductility and resistance to acids.

Manganese (Mn)

≤ 2.0%

Boosts strength and formability.

Silicon (Si)

≤ 0.75%

Aids in deoxidation and scaling resistance.

Phosphorus (P)

≤ 0.045%

Controls impurities to prevent material degradation.

Sulfur (S)

≤ 0.03%

Minimizes brittleness for better machinability.

Nitrogen (N)

≤ 0.10%

Increases pitting resistance and overall strength.

Gangsteel maintains rigorous quality control for SA240 304 sheets, aligning with JIS G 4304 stainless steel plate standards for international compatibility.

 

Mechanical Properties of SA240 304

SA240 304 sheets exhibit balanced mechanical properties suitable for fabrication and structural use. The table below summarizes these as per ASME SA240:

Property

SA240 304 Value

Description

Tensile Strength (min)

515 MPa (75 ksi)

Maximum stress the sheet can withstand before breaking.

Yield Strength (min)

205 MPa (30 ksi)

Stress at which plastic deformation begins (0.2% offset).

Elongation (min)

40% (in 2 inches)

Measure of ductility, showing stretchability before fracture.

Hardness (max)

201 HBW (Brinell) or 92 HRB (Rockwell B)

Resistance to surface indentation, indicating wear resistance.

Density

7.93 g/cm³ (7930 kg/m³)

Essential for weight calculations in design and engineering.

These properties make SA240 304 sheets superior to budget options like SA240 Gr 201, while Gangsteel offers variants like SA240 Gr 304L for enhanced weldability.

 

Equivalent Materials for SA240 304

SA240 304 has several international equivalents, allowing for flexible sourcing and application. The table below lists common equivalents:

Standard

Equivalent Grade

Description

UNS

S30400

Unified Numbering System designation for global identification.

EN/DIN

Applications of SA240 304 Material Sheets

SA240 304 sheets are adaptable to numerous industries due to their corrosion resistance and formability. The table below highlights key applications:

Industry

Application

Related Products

Chemical Processing

Sheets for tanks, reactors, and liners handling mild corrosives.

SA240 Gr 317L, SA240 Gr 316L

Food Manufacturing

Hygienic surfaces for equipment like conveyors and storage units.

SA240 Gr 301

Automotive

Exhaust systems and decorative trims requiring durability.

SA240 Gr 409

Gangsteel’s ASME SA 213/SA 213M stainless pipes integrate well with SA240 304 sheets for comprehensive systems.

 

Weight Calculation for SA240 304 Material Sheets

The density of SA240 304 is 7.93 g/cm³ (7930 kg/m³). To calculate the weight of a sheet:

Weight (kg) = Density (kg/m³) × Volume (m³)
Volume (m³) = Length (m) × Width (m) × Thickness (m)

Example:

  • Sheet: 3 meters long, 1.5 meters wide, 3 mm (0.003 meters) thick.
  • Volume = 3 × 1.5 × 0.003 = 0.0135 m³.
  • Weight = 7930 kg/m³ × 0.0135 m³ ≈ 107.1 kg.

This is vital for logistics in projects using SA240 Gr 304 or equivalents like SA240 Gr 310S.
