*2.2.3 Other hardbanding materials*

The development of new hardbanding materials with high performance has already attracted the attention of the industry. Many technical service companies have developed new materials. Major products can be found in the following:

#### *2.2.3.1 Postle industries hardbanding*

Postle Industries has developed some new hardbanding materials, such as Duraband® NC hardbanding and Tuffband® NC hardbanding:

Duraband® NC from Hardbanding Solutions is a 100% crack-free casingfriendly hardbanding, which can provide maximum protection of the tool joint and casing as well as workstring completion tubing [22]. Duraband® NC consists of a hard but tough tool steel matrix with a high volume of tightly packed micro-constituents, which ensures a non-cracking hard band with excellent wear resistance in open hole drilling as well as being casing friendly.

Tuffband® NC is a high hardness hardbanding which can meet different application requirements [23]. When used by itself, it is especially suitable for casingfriendly hardbanding applications. When casing protection is not a factor, it can be used as a weld matrix with tungsten carbide (WC). Tuffband® NC is applied crack free and prevents spalling even under the most extreme drilling conditions and is 100% rebuildable.

#### *2.2.3.2 TE metal works hardbanding*

TE Metal Works specialize in 100% nonmagnetic applications for all directional and vertical drilling. TE NM1X hardbanding developed by TE Metal Works is an alloy which is 100% nonmagnetic and 100% crack free [24]. This hardbanding will outlast 3 times the length of non-mag welding alloys.

#### *2.2.3.3 HBK series hardbandings*

HBK series hardbandings are developed by Kooben Technology [25]. Kooben is only one company in China with the ability to research, develop, and manufacture hardbanding. Kooben's hardbanding product line now has three grades. They are HBK 100, HBK 150, and HBK 300, which are suitable for any application. The performances of their hardbandings are similar to those of Arnco hardbandings. They can offer at the industry's most competitive prices and are compatible with all Arnco hardbandings. Besides, the client testing phase of nonmagnetic hardbanding wire has begun. In addition, Kooben is also one of the few companies in the world that have nonmagnetic hardbanding wire products.
