SA 240 Gr 304 Material Specification PDF: Gangsteel Stainless Solution in China

 

Introduction to SA 240 Gr 304 Material Specification PDF

The SA 240 Gr 304 material specification PDF is a comprehensive document detailing the requirements for ASME SA240 Grade 304 stainless steel, a widely used austenitic alloy for plates, sheets, and strips in pressure vessels and general applications. This specification covers chemical composition, mechanical properties, heat treatment, and testing methods to ensure material integrity. Grade 304 is known for its corrosion resistance and strength, making it ideal for industries like chemical processing and food production. Gangsteel, a leading manufacturer and exporter in China, provides SA 240 Gr 304 compliant products with downloadable PDFs upon request.

As specialists in ASME SA240 stainless steel plates, Gangsteel offers customized solutions for global clients. This article summarizes the key details from the SA 240 Gr 304 material specification PDF, including ss 304 plate density, sa-240 304l material, and other variants.

 

What is SA 240 Gr 304 Material?

SA 240 Gr 304 material is an austenitic chromium-nickel stainless steel (UNS S30400) specified in the ASME SA240 standard. It is designed for pressure vessels and general use, with excellent weldability and formability. Equivalent to EN 1.4301 and JIS SUS304, it is non-magnetic and resistant to mild corrosives. For low-carbon versions like sa 240 304l material, carbon is limited to 0.03%. Gangsteel’s SA240 Gr 304 meets the specification, suitable for sa 240 type 304 304l applications.

 

Chemical Composition from SA 240 Gr 304 Specification PDF

The SA 240 Gr 304 material specification PDF requires the steel to conform to specific chemical limits. The table below details the composition for UNS S30400 (Grade 304):

Element

Maximum (%)

Purpose

Carbon (C)

0.08

Enhances strength; limited to prevent sensitization.

Manganese (Mn)

2.00

Improves hot workability.

Phosphorus (P)

0.045

Controlled for quality.

Sulfur (S)

0.030

Minimized for corrosion resistance.

Silicon (Si)

0.75

Aids in oxidation resistance.

Chromium (Cr)

18.0–20.0

Provides corrosion protection.

Nickel (Ni)

8.0–10.5

Stabilizes austenitic structure.

Nitrogen (N)

0.10

Boosts strength (optional).

For sa 240 304h material (high carbon) or sa 240 304l material (low carbon), limits vary slightly. Gangsteel ensures compliance for materiale sa 240 304 and sa-240-304 material.

 

Mechanical Properties from SA 240 Gr 304 Specification PDF

The specification PDF outlines mechanical requirements tested per ASTM A370. For SA 240 Gr 304:

Property

Minimum Value

Description

Tensile Strength

515 MPa (75 ksi)

Maximum stress before breaking.

Yield Strength (0.2% offset)

205 MPa (30 ksi)

Stress at plastic deformation.

Elongation (in 2 in.)

40%

Measure of ductility.

Hardness (Brinell)
