Japanese Standard Flake Graphite Type Pearlite Cast Iron Serials, Tensile Strength, and Chemical Compositions (Mass Fraction) (%)

Japanese Standard Flake Graphite Type Pearlite Cast Iron Serials is a type of cast iron. This type of cast iron is known for its excellent tensile strength and chemical composition. It is well suited for a variety of engineering applications such as general machine tools and other heavy-duty industrial machinery. It is a cost effective material as compared to other cast iron varieties.

In this article, we will look at some of the characteristics, serials, tensile strength and chemical composition of Japanese Standard Flake Graphite Type Pearlite Cast Iron Serials.

Characteristics of Japanese Standard Flake Graphite Type Pearlite Cast Iron Serials

Japanese Standard Flake Graphite Type Pearlite Cast Iron Serials exhibits excellent wear resistance, good fatigue strength and high ductility. It has a high carbon content and a good amount of pearlite which gives it good toughness. The toughness of pearlite is due to its combining of grain with a uniform distribution of graphite in the matrix. The presence of graphite makes the material less brittle and more resistant to shock loads. The graphite also increases its high temperature performance.

Serials of Japanese Standard Flake Graphite Type Pearlite Cast Iron Serials

Japanese Standard Flake Graphite Type Pearlite Cast Iron Serials is classified into four main categories based on its mechanical and chemical properties.

The categories are as follows; FC250, FC300, FC350 and FC400.

FC250 has the lowest tensile strength of 250N/mm2 but it has high ductility and toughness. It also has good machinability and corrosion resistance.

FC300 has a tensile strength of 300N/mm2 and it has a high resistance to shock and impacts. It is suitable for use in components for the machinery industry.

FC350 has a higher tensile strength of 350N/mm2 and is suitable for use in structural trucks and other structural components.

FC400 has the highest tensile strength of 400N/mm2 and is used in highly stressed components such as shafts and gears.

Tensile Strength of Japanese Standard Flake Graphite Type Pearlite Cast Iron Serials

The tensile strength of Japanese Standard Flake Graphite Type Pearlite Cast Iron Serials ranges from 250N/mm2 to 400N/mm2 depending on the serial number. It has excellent fatigue strength and its strength can be further increased by applying proper heat treatment techniques.
