Work Hardening Alloys
These alloys are designed to produce an austenitic matrix containing high amounts of manganese and nitrogen. The combination of these additions produces a rapid work hardening rate and high work hardening capacity. Some grades contain chromium and nickel to offer higher strength and better impact properties.
Low & Medium Alloyed Steels
These materials are used in various applications where mostly a combination of high strength and high toughness is required. The wear resistance is improved at the expense of ductility by the increased amount of chromium and carbon.
Tool steel filler materials are designed to possess excellent mechanical properties at elevated temperatures. While low alloy grades are easily machinable and can be used for buffering, chromium-molybdenum medium carbon containing alloys are used in severe pressure conditions at high temperatures. More complex tungsten and vanadium containing alloys are preferred in cutting tools where the number of layers are restricted to one or two.
Abrasion Resistant Alloys
A vast range of alloys can be classified into several groups based on their carbide forming constituents :
Alloys containing primary chromium carbides with varying Cr/C ratios in an austenitic or martensitic matrix
Alloys with primary titanium or niobium carbides
Materials with complex carbides designed for high temperature applications
Boron containing materials for severe abrasion conditions.
Martensitic/Ferritic Stainless Steels
These alloys contain chromium varying from 9% to 16% with carbon level from 0.03 to 0.5%. The microstructure is mostly martensitic with small amounts of delta ferrite and retained austenite depending on the overall chemistry and the welding conditions. The filler materials are designed for various applications and the properties are enhanced by additions of nickel, molybdenum, vanadium, tungsten, cobalt and other grain refining elements.
Nickel Base Alloys
These alloys are designed for extreme corrosive environments. The alloys mostly consist of a high strength corrosion resistant Ni-Cr-Mo matrix with some precipitation hardening.
Austenitic Stainless Steels
The series of austenitic stainless steels are available in the form of solid wires. They are extensively used for cladding and joining for corrosive and high temperature environments.
Duplex Stainless Steels
Austentitic/ferritic dual phase duplex and super duplex stainless steels in the form of solid wires designed for highly corrosive environments where a combination of strength and excellent pitting resistance is required.
Wires for Welding Cast Iron
Nickel and nickel-iron solid wires are designed to weld cast iron parts. They are also suitable for joining and repair of cast irons and can be used for welding nodular ductile iron containing spheroidal graphite.
