GGG 40 steel grade is a type of ductile iron that has excellent mechanical properties and is commonly used in various industries.
Some of the mechanical properties of GGG 40 steel grade include a minimum tensile strength of 400 MPa, minimum yield strength of 250 MPa, and minimum elongation of 12%. These properties make it suitable for applications that require high strength, good ductility, and resistance to wear and impact.
The chemical composition of GGG 40 steel grade typically consists of 3.50-3.90% carbon, 2.40-3.20% silicon, 0.15-0.30% manganese, 0.02-0.04% phosphorus, and 0.025-0.06% sulfur. Additionally, it contains small amounts of other elements such as chromium, nickel, and copper.
Industries that commonly use GGG 40 steel grade include automotive, construction, machinery, and general engineering. Its high strength and ductility make it suitable for applications such as engine components, gears, and structural parts. Its resistance to wear and impact also makes it suitable for use in heavy machinery and equipment.
Overall, GGG 40 steel grade offers a good combination of mechanical properties and chemical composition, making it a versatile material for various industrial applications.
