Product Description

Products Details

Malleable Iron 131R Reducing Tee. Reducing tee is a kind of connection pipe fittings with different size for three ways.Strength refers to the ability of a metal to resist permanent deformation and fracture. Tensile strength, yield point, etc. are commonly used to characterize the properties of metal materials. Tensile strength (strength limit) is the maximum stress a material can withstand before breaking. Tensile strength is one of the main mechanical indicators of metal materials. Because it represents the maximum stress value that the material can withstand under tensile conditions, it is also one of the main indicators in part design and material selection. The tensile strength of our Malleable cast iron is 330 Mpa, 10% higehr than the standard.

Our products

Plasticity refers to the ability of a metal material to plastically deform under the action of external forces without being destroyed. Commonly used plasticity indicators include elongation after fracture and shrinkage of area. The larger the values of elongation after fracture and shrinkage of area, the better the plasticity of the material.The elongation of our malleable iron pipe fittings is 10%, 66% higher than the standard.Good plasticity ensures the smooth progress of pressure processing and welding, and ensures the safety and reliability of parts during work.
