Metallographic grinding and polishing insight

How to select a preparation method

The Metalogram displays materials according to specific physical properties: hardness and ductility. 

• Hardness:

  T

  With competitive price and timely delivery, sino welding sincerely hope to be your supplier and partner.

  he easiest attribute to measure but is not sufficient information about a material to find the correct preparation method.

• Ductility:

  The ability of a material to deform plastically is important for grinding and polishing. This property expresses how the material responds to mechanical abrasion.

The X-axis represents the hardness in Vickers (HV). The values are not shown in a linear progression, because the variety of preparation methods for softer materials is greater than for hard ones. The shape of the Metalogram results from soft materials generally being more ductile and hard materials usually being more brittle.

Selection of a Preparation Method

1. Find the hardness on the X-axis.

2. Move up or down, depending on the ductility of the material. Unlike hardness, ductility is not easily defined in precise numbers.

3. Place the material on the Y-axis according to any previous experience. A prerequisite is to have an idea of how a ductile or brittle material will perform.

Product Description

Product Descripition

The surface alloy layer of this product has high hardness and excellent wear-resistant performance.The base metal is a common rolled plate with good toughness and plasticity.The wear-resistant alloy layer and the base metal are metallurgy combined and firmly combined in service,wear is resisted by the high hardness of the surface allov aver. And the impact of external force is resisted by the strength and toughness of the matrix.
