Understanding EN-GJS-500-7 Properties and Specifications
EN-GJS-500-7, also known as Grade 500-7 spheroidal graphite (SG) iron, is a versatile cast iron alloy. It's widely used in many industries. Its chemical composition and microstructure are key to its exceptional mechanical properties. Let's dive into the details of this grade.
Chemical Composition and Structure
The typical chemical composition of EN-GJS-500-7 includes:
- Carbon (C): 3.40-3.85%
- Silicon (Si): 2.30-3.10%
- Manganese (Mn): 0.10-0.30%
- Sulphur (S): ≤0.02%
- Phosphorous (P): ≤0.10%
- Magnesium (Mg): ≤0.07%
The microstructure features roundedgraphite nodules. These nodules enhanceductilityand prevent cracks. Manufacturers adjust the composition to meet specificmechanical properties.
Mechanical Properties and Standards
EN-GJS-500-7 has impressive mechanical properties, including:
- Minimum tensile strength of 500 MPa
- Minimum yield strength of 320 MPa
- Minimum elongation of 7%
- Brinell hardness range of 170-230 HB
This grade meets BS EN 1563 (2011) and ISO 1083 (2004) standards. Tensile strengthandelongationare crucial for qualification. It's also known as ISO 500-7, China QT500-7, USA ASTM A536 70-50-05, and Japan FCD500.
"The rounded graphite nodules in the structure produce a more ductile cast iron that inhibits crack formation."
Applications and Uses of Grade 500/7 SG Iron
EN-GJS-500-7 ductile iron, also known as Grade 500/7 SG iron, is very versatile. It's used in many industries because of its strength and ability to dampen noise and vibrations. This makes it perfect for parts that need to be tough and quiet.
In the car industry, EN-GJS-500-7 is used to make valve bodies, gears, and pistons. It's great because it can handle the tough conditions cars face every day.
But it's not just cars. EN-GJS-500-7 is also used in machinery parts and industrial equipment. It's strong, making it ideal for iron brackets for trucks, tractors, and other machinery. It's also used to make dies and molds because it's stable and easy to work with.
