Description:
OTW 10SS is an exclusive gas shielded, metal cored alloy wire, specifically designed for use in severe sour (SS) environments
and is fully compatible with all drill pipe sour service grades. Drill pipe sour service grades (VM 105 DP SS™, TSS™-105,
CYX™-105) and HWDP differ greatly from normal API grades and use a modified form of steel on the pipe body and tool
joints.
This alloy is formulated to be non-cracking, easy to apply and repair, with low dilution and minimal pre-heat temperatures.
The reduced overall hardness is designed to optimize performance in even the most severe sour environments.
OTW 10SS is formulated to produce a unique, hard tool-steel microstructure with numerous ultra-fine/ultra-hard phases,
dispersed in a tough tempered martensitic matrix.
OTW 10SS produces an excellent, non-spatter bead in both appearance & quality, ensuring greater flexibility & increased
arc stability between 100 to 400 AMP operating ranges”. Reducing labor costs, OTW 10SS offers a high deposition rate
with exceptional, all-position welding ability. The result is a cost-effective solution for multi-purpose hardbanding
applications, including Drill Pipe Tool Joints, HWDP Tool Joints & Center Wear Pads.

Compatibility Conclusions: OTW 10SS
Product A – This product is non compatible and has cracking and galling issues
Product B – Leading Ti containing repair product
Product C – Leading overall in non-cracking
Product X – Leading non-cracking, casing friendly product with poor open hole performance
After rewelding with OTW 10SS over the 7 welded hardbanding alloys, all the hardbanding overlay is examined
visually for cracks and then cut and polished to study the interface between the new and old hardbanding prod-
ucts. There should be a smooth transition with no crack formation and the micrographs of transition zone be-
tween different alloys and OTW 10SS are recorded and studied.
OTW 10SS has been shown to be not only fully compatible (interchangeable) with itself, but also with the other products
in the OTW range, OTW16 XS, OTW12 Ti and OTW13 CF plus the most commonly used hardbanding alloys available in
the market today.

Non-Cracking Design (NCD)
Most hardbanding products have a high hardness and different thermal expansion coefficient to that of the tool joint
material that they are welded to. These mechanical differences plus the thermal stress created during welding results
in high tensile stresses in the hardbanding layer, which are usually relieved by controlled cracking of hardbanding.
The OTW range are all Non-Cracking Designed alloys. Not only this NCD feature give advantages in reducing casing
wear, but when OTW 10SS is used it can save up to 75% of re-application costs compared to when using commercial
products that are cracking. The table below demonstrates the reduction in the number of processes required with its
consequential significant cost reduction.
OTW 10SS is designed to be crack free on tool-joints, this has been done for over 6 years and with continuous success
when the welding procedure in the OTW Hardbanding Application Manual is followed.
