What is the difference between pure nickel N02200 (Ni200) and N02201 (Ni201)?
The following article explains how to distinguish the pure nickel alloy grades N02200 (Ni200) and N02201 (Ni201):
First, give some basic introduction to N02200 (Ni200) and N02201 (Ni201):
N02200/Ni200 pure nickel is a multifunctional and extremely important metal material. It is widely used in industry because of its good strength and plastic toughness. In addition to forming valuable alloys with other metals, pure nickel has good properties. Used alone as corrosion-resistant structural materials and functional materials. In fact, pure nickel used as corrosion-resistant structural materials is a nickel-carbon alloy containing carbon.
N02201/No2201 pure nickel is a multifunctional and extremely important metal material. It is widely used in industry because of its good strength and plastic toughness. In addition to forming valuable alloys with other metals, pure nickel has good properties Used alone as corrosion-resistant structural materials and functional materials. In fact, pure nickel used as corrosion-resistant structural materials is a nickel-carbon alloy containing carbon.
In summary, the N02200 (Ni200) and N02201 (Ni201) mentioned above are both pure nickel alloys, which also contain the metallic element carbon, making them also called nickel-carbon alloys.
A convenient and concise way to distinguish metal materials is to compare the chemical metal components:
N02200/Ni200 chemical metal composition (%):
Carbon C: ≤0.15,
Silicon Si: ≤0.35,
Manganese Mn: ≤0.35,
Sulfur S: ≤0.01,
Nickel: 99,
Cobalt Co: 99,
Iron Fe: ≤0.40,
Copper Cu: ≤0.25.
N02201 (Ni201) chemical metal composition (%):
Carbon C: ≤0.02,
Silicon Si: ≤0.35,
Manganese Mn: ≤0.35,
Sulfur S: ≤0.01,
Nickel: 99,
Cobalt Co: 99,
Iron Fe: ≤0.40,
Copper Cu: ≤0.25.
In each standard, their names are different, but their material usage characteristics are roughly the same:
N02200/No2200 corresponding grades:
National brand number: N8,
American label: Nickel200, No2200,
German brand number: 2.4066, Nickel99.2
N02201/No2201 corresponding grades:
National brand number: N6,
American label: Nickel201, No2201,
German brand number: 2.4068, Nickel99
The environment in which metal materials are used will cause corrosion, wear and fracture properties of the materials, so material selection needs to be given priority.
Regarding the corrosion resistance properties of N02200 (Ni200) and N02201 (Ni201) materials complained about in this article, the following is a brief introduction:
Corrosion resistance of N02200 (Ni200): It corrodes very slowly in the atmosphere. It has good corrosion resistance in seawater and HCl in various hydrochloric acids. However, it should be used with caution in HIC acids with high flow rates. It is not available in H3PO4 and HNO3. , H2SO4 can only be used in H2SO4 without air, has good corrosion resistance in high temperature anhydrous HF, has good corrosion resistance in high temperature chlorine and HCl, has good corrosion resistance in chlorine and fluorine gas corrosion resistance.
N02201/No2201 Corrosion Resistance: It corrodes very slowly in the atmosphere. HCl has good corrosion resistance in seawater and various hydrochloric acids. However, it should be used with caution in HIC acids with high flow rates. It is not usable in H3PO4 and HNO3. H2SO4 can only be used in airless H2SO4. It has good corrosion resistance in high-temperature anhydrous HF, has good corrosion resistance in high-temperature chlorine and HCl, and has good corrosion resistance in chlorine and fluorine gases. Corrosion resistance, and its welding resistance to intergranular corrosion will be even better (mainly due to its reduced carbon content).
