GG 15 Steel Grade: The Unbeatable Solution for High-Temperature Applications

GG 15 Steel Grade is a type of gray iron alloy that is specifically designed for high-temperature applications. It is known for its unbeatable performance and reliability under extreme heat conditions.

Mechanical Properties:
– Tensile Strength: GG 15 Steel Grade has a tensile strength of around 200 MPa, which allows it to withstand high loads and stresses.
– Yield Strength: This steel grade has a yield strength of approximately 150 MPa, indicating its ability to resist deformation under load.
– Hardness: GG 15 Steel Grade has a hardness of 180 to 220 Brinell, ensuring its durability and resistance to wear.
– Ductility: It exhibits good ductility, which means it can be easily shaped or formed without breaking or fracturing.

Chemical Composition:
– Carbon (C): GG 15 Steel Grade typically contains a carbon content of 3% to 3.5%. Carbon provides strength and hardness to the alloy.
– Silicon (Si): It has a silicon content of around 2.2% to 2.5%. Silicon improves the casting fluidity and promotes the formation of graphite flakes, enhancing the alloy’s heat resistance.
– Manganese (Mn): GG 15 Steel Grade contains manganese in the range of 0.8% to 1%. Manganese aids in the formation of pearlite, which improves the alloy’s strength and wear resistance.
– Phosphorus (P): It has a phosphorus content of less than 0.3%. Phosphorus helps improve the castability of the alloy.
– Sulfur (S): GG 15 Steel Grade typically has a sulfur content of less than 0.1%. Sulfur improves the machinability of the alloy.
– Iron (Fe): Iron is the main component of GG 15 Steel Grade, constituting the majority of its composition.

GG 15 Steel Grade’s unparalleled mechanical properties and optimized chemical composition make it the ultimate choice for applications requiring resistance to high temperatures. It is commonly used in automotive, industrial, and engineering sectors where components are exposed to extreme heat and thermal stress.
