عربىIron-based alloy powder is made by adjusting the Ni and Cr content of 18-8 or Cr13-type stainless steel and adding B and Si elements.
This type of material is widely used in mechanical engineering. It is good strength, wear resistance, wide range of sources, low price, generally used in mechanical parts working at room temperature, for sliding surfaces of the hard surface coating and wear parts of the size, but the melting point of this type of material is high, spraying is easy to cause oxidation and coating porous and so on.
This series of alloys wear resistance, pressure resistance and toughness is good, easy to process, used for wear-resistant parts and shaft pump surface, turbine box body sealing surface and other parts.
Weldments in the case of dynamic loads and impact loads, in addition to the requirements to ensure that the tensile strength, yield strength, impact toughness, plasticity have higher requirements. At this time should be used low hydrogen type welding consumables.
Some welding consumables are only suitable for welding in a certain position, the other position of the welding effect is poor, some welding consumables are in a variety of positions that can be welded, the selection should consider the characteristics of the welding position.
Weldments work in corrosive media, distinguish the type of media, concentration, working temperature, and corrosion type (general corrosion, intergranular corrosion, stress corrosion, etc.), so as to select the appropriate stainless steel welding consumables.
Iron-based alloy powder is made by adjusting the Ni and Cr content of 18-8 or Cr13-type stainless steel and adding B and Si elements.
Alloy wear resistance, pressure resistance and toughness is better, easy to process, used for wear-resistant parts and shaft pump surface, turbine box body sealing surface and other parts. Because it contains boron, silicon and other elements, it is self-melting and can be sprayed directly or remelted, and can be used for laser cladding.
