Nickel 201 is the low-carbon version of Nickel 200.
Because of its low carbon content, Nickel 201 is not subject to embrittlement by intergranularly precipitated carbon or graphite when exposed to temperatures of 315 to 760℃ for prolonged time if carbonaceous materials are not in contact with it.
However it does suffer from intergranular embrittlement by sulfur compounds at temperatures above 315℃.
Sodium peroxide can be used to change them to sulfates to counteract their effect.
APPLICATIONS
Electronic components, caustic evaporators, combustion boats and plater bars.
Our pipe factory has 296 employees ,including 4 senior engineers,18 engineers and 38 professional technicians.
We can produces 30,000tons of austenitic steel and duplex steel pipes annually with 18 seamless production lines and 3 perforation production lines.
Our pipe factory has been certified to the ISO9001:2015 quality management system and certified by various classification societies (such as BV, ABS,CCS,DNV/GL,TUV,LR,KR etc).

Quality Control Of Huashang Duplex Steel Seamless Pipe |
1. Raw Materials
Our raw materials come from well-know mills in China, such as Tingshan, Tisco, Bao Steel, Yongxing, Walsn.....
We will do MTC checking (PMI), tensile strength test, surface/dimension inspection for raw material.
2. Production
Specially assigned person shall follow up and check the process flow card and finally keep the copy.
3. Before Shipment
Our quality inspection team responsible for different categories of products. We will conduct routine appearance testing, PMI testing, non-destructive testing. We also equipped with a professional lab that can do physical and chemical properties test. we also can accept the third inspection, such as BV, LR, TUV, ABS, DNV-GL ect.
