22 INCH TO 48 INCH ASME B16.47 Series A B Welding Neck Blind Nickel 200 flange
1. Nickel 200 (UNS N02200) Introduction
This is commercially pure (99.6%) nickel, It has good mechanical properties and excellent resistance to many corrosive environments. Annealed nickel has low hardness, good ductility and good weldability, making the metal easy to fabricate. The metal has a low work-hardening rate, but it may be cold worked to moderately high strength levels while maintaining ductility.
| CHEMICAL ANALYSIS NICKEL 200 |
| (Ni + Co) | Nickel + Cobalt 99.00 min |
| Cu | Copper 0.25 max |
| Fe | iron 0.045 max |
| Mn | Manganese 0.035 max |
| C | Carbon 0.15 max |
| Si | Silicon 0.35 max |
| S | Sulfur 0.1 max |
| NICKEL 201 IS THE LOW-CARBON VERSION, AT 0.02 MAX CARBON |
APPLICATIONS
Nickel 200 the metal finds applications in the handling of foods, synthetic fibers and caustic alkalies, and also in structural applications where corrosion resistance is of prime importance. It is further used in chemical shipping components, electrical and electronic parts and in aerospace and missile components.
Nickel 201 is used for caustic evaporators, combustion boats, plater bars and electronic components. It is more suitable than nickel 200 for applications involving exposure to temperatures above 600ºF (315ºC).
Nickel 201 is used for caustic evaporators, combustion boats, plater bars and electronic components. It is more suitable than nickel 200 for applications involving exposure to temperatures above 600ºF (315ºC).
FORGING
Both grades will be forged between 2200/1600ºF (1205/870ºC), but light forging may be carried out below 1200ºF (650ºC) to improve mechanical properties.
HEAT TREATMENT
The alloy is annealed as a ‘recovery’ from cold work, at temperatures that may vary from, say, 1100ºF (595ºC) through 1700ºF (925ºC) depending upon the metal’s mechanical working history. Controlled atmospheres should be used to maintain the metal’s appearance.
It should be noted that long exposure of Nickel 200 to temperatures in the range 800/1200ºF (425/650ºC) will result in graphite precipitation. Nickel 201 should be used for such applications.
MACHINABILITY
Annealed material tends to form long, stringy chips, whereas material that has had a degree of cold work will machine more easily. High-speed steel or cast-alloy tools are recommended
WELDABILITY
Both Nickel 200 and Nickel 201 may be welded using conventional processes, but oxy acetylene welding should not be used on Nickel 201 due to the danger of carbon pickup.
