Add value to your pumps and drilling devices and complete product range.

Wear resistance, toughness, corrosion resistance, and resistance to thermal shock are the key material properties required for long-lasting, all-perfect pump function.

The unique combination of all these material characteristics has made Cemented Carbide the most widely used material in carbide tools as pump seals and bearing in the sewage, mining and process sectors. Moreover, there is further potential to tailor Cemented Carbide for a vast range of environmental applications.

Adapted grades offering to meet the performance and production techniques adopted by the customers

Metal Cutting
Cemented Carbide and Cermet grades provide the toolmaker with a productivity solution for different applications and cutting conditions, extending tool life and ease of tool fabrication.There are grades suitable for example for non-ferrous cutting applications, where the saw blade cuts through materials as UPVC and aluminum, as for interrupted cutting applications.

Wood Cutting
Cemented Carbide and Cermet grades provide the toolmaker with improved edge quality without reduction in brazing and grinding characteristics.

A grade offering for Wood Cutting has been developed by extensive research and development into the cutting characteristics needed for circular saws. Through the introduction of DC (anti- corrosive) and DH (next generation) grades we provide materials that give optimum performance for wood cutting tools.

Combine excellent pass form wear resistance with high strength and toughness in the roll body.

Carbide tools and carbide components optimizes the hot rolling mills. The cast-in-carbide (CIC) concept takes this material a step further, as demonstrated in hot rolling mills all over the world. The CIC technology offers new opportunities for rolling mill managers to improve product quality, reduce down-time and increase productivity. Cemented Carbide manufacture is a highly specialized area, involving many different metallurgical, chemical and mechanical processes. The main stages from powder to finished roll blank are pressing, shaping and sintering. A pressing capacity of up to 1,200 tons places our powder pressing facilities in a class of their own. In the direct sintering process, the shaped blanks are heat-treated to a well-defined temperature and time exposure, depending on the particular carbide grade.

Carbide rolls have reached their correct hardness after the sintering process is complete. This hardness makes the rolls very difficult to machine. Because of this difficulty, it is important that we engineer each product to be as close as possible to their final dimension during the manufacture of the blanks. Grinding is normally utilized for machining the final roll shape. Grades with 25 and 30% binder can also be machined by turning.

In today's competitive Oil & Gas drilling environment, the pursuit of faster, economical and superior wells has conjured a host of technological advances.

However, in the end, it all comes down to the drilling bit. Cemented Carbide is an ideal material for drilling inserts and carbide drill bits due to its high hardness, compressive strength and thermal conductivity. Research and Development within Sandvik Hard Materials has taken these properties and used innovative techniques to improve the toughness and impact resistance, while reducing the risk of thermal effects of the carbide drill bits during drilling.

The variety of material that Sandvik can supply provides coverage for a variety of application needs. In soft rock/heat generation formations, engineers typically select grades that are extra coarse with high binder content. These characteristics result in high fracture toughness and prolonged carbide drill bit life. Medium coarse grades with low binder content are generally used in drilling hard formations. This results in high hardness (better abrasion resistance), but low fracture toughness, ultimately having a higher penetration rate but increased likelihood for fracture.

Sandvik manufactures a large variety of inserts and carbide drill bits used in rotary & percussion rockbits for Oil & Gas and mining industries. Extreme drilling conditions, whether rotary, percussion or downhole, require unique solutions. Sandvik has the technology to supply the customers with inserts and carbide drill bits that perform every time.
