Hastelloy B3 Nickel Alloy Fasteners Heavy Hex Nut 1/4"-4" ASME B 18.2.2

1.Hastelloy B3 description

Hastelloy B-3 is a nickel-molybdenum alloy with excellent resistance to pitting, corrosion, and stress-corrosion cracking plus, thermal stability superior to that of alloy B-2. In addition, this nickel steel alloy has great resistance to knife-line and heat–affected zone attack. Alloy B-3 also withstands sulfuric, acetic, formic and phosphoric acids, and other non-oxidizing media. Furthermore, this nickel alloy has excellent resistance to hydrochloric acid at all concentrations and temperatures. Hastelloy B-3’s distinguishing feature is its ability to maintain excellent ductility during transient exposures to intermediate temperatures. Such exposures are routinely experienced during heat treatments associated with fabrication.

3.Fasteners package method


Often small hardware, fasteners and other parts are packaged in bags and displayed in bins or on
hangers. Bagging is the most effective way to package and organize small parts, while also being the
most flexible and affordable. In order to better protect the products during transportation, we will pack the
packed products in wooden cases.

4.Fasteners Application

A fastener (US English) or fastening (UK English) is a hardware device that mechanically joins or affixes
two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints
that can be removed or dismantled without damaging the joining components. Welding is an example of
creating permanent joints. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel.

7.Production Flow

Huitong Group was established in 1978. After 38 years'development and innovation,by now,Huitong Group has set up multiple subsidiary companies.Among them,Zhengzhou Huitong Pipe Fitting Co.,Ltd.,with the indepent right of import and export, is mainly engaged in exporting steel pipe and pipe fittings for Huitong Group and assisting another subsidiary company of Huitong Group:Zhengzhou Huitong Machanical Equipment Co.,Ltd., in exporting machanical equipment.

Zhengzhou Huitong Pipeline Equipment Co.,Ltd.,with the strong support of Huitong Group,and years'development and innovation, are more and more professional in technical service and can manufacure products with all kinds of material,shape and size. Especially in elbows, tee, reducer, flange and pipe cap etc., we have gained more than 20 product patent, and hundreds of technology patent. Also,we have gradually taken an ireplacable role in High-pressure,high-temperature and anti-corrosion area. With the continuous construction of engery in China,such as petrol gas,electric power,etc.,our company has become the purchasing center of whole set fittings for such projects.In 2009,a foreign trade team established,is manily engaged in oil gas and electric power projects abroad.By now, our products have been exported to

Canada,Malaysia,Parkistan,UAE, Eygpt,the Middle East countries, etc.. We have passed the qualification of ISO9001:2000 and API quality certification system.
