We supply different grades of boron steel for agricultural machines, such as plows and many other products where wear resistance is a critical issue.

Boron steels are used in wear resistance parts and fasteners for agricultural, forestry and off-road vehicles. Boron alloying even in small quantities significiantly increases the hardenability of steel, allowing lower contents of carbon and other alloying elements.

The benefits are:
low hardness in the rolled condition
good weldability
good formability
a good combination of high tensile strength and tougness after quenching and tempering.

Abrasive wear in industrial applications such as mining, materials handling and agricultural machinery constitutes a large part of the total wear. Hardened high strength boron steels are known for their good wear resistance and mechanical properties, but available results in the open literature are scarce. This work aims at investigating how different quenching techniques affect the two-body abrasive wear resistance of hardened high strength boron steels. Furthermore, the wear as a function of depth in thicker hardened high strength boron steel plates has also been studied. The material characterisation has been carried out using microhardness, SEM/energy dispersive spectroscopy and three-dimensional optical surface profilometry. The results have shown that water quenched and tool quenched high strength boron steel had similar wear resistance. The main wear mechanisms appear to be microcutting combined with microfatigue. Workhardening during the abrasion process has been found to affect the abrasive wear.

Boron is a small interstitial element which is added to fully killed and de-oxidised steel to improve hardenability.
Boron-treated steels are produced in the range 0.0005 – 0.005% added boron and are most effective in lower carbon steels < 0.40% C.
Boron increases the strength of heat-treated steels in the quenched and tempered condition.
Boron can be substituted for other alloying elements, maintaining the hardenability.
Boron steel grades can be hot worked using cooled tooling by pressing, bending and forging. Quenching from hot working temperature; produces a rapid cooling rate and a martensitic microstructure which is auto-tempered to produce high strength, tough, hard, durable and wear resistant components.
Applications
An economically attractive alternative to conventional engineering steels with process and production benefits.
The combination of good abrasion resistance and high strength, allow innovative freedom of design.
Fork-arms for materials handling use 0.30% carbon manganese boron steel modified with minor additions of chromium and/or molybdenum.
Wear components including; ground engaging tools, wear plate, screen plate, punching tools, spades, knives, saw blades and caterpillar tracks
Structural components including; safety parts in automotive, agricultural machinery.
Alternative to hot work tool steel H13 and cold work tool steel D2 in fork-arm manufacturing.
Steel-making
Boron has a great affinity for oxygen and nitrogen and if allowed to combine the hardenability benefits will be lost. Therefore, the steel must be fully de-oxidised and a strong nitride forming element added.
Aluminium is used to reduce the oxygen level and Titanium to reduce the nitrogen level; typically residual levels ~ 0.030%.
Boron steels can be manufactured with modified inclusions and low inclusion counts to aid formability in the through thickness direction.
Hardenability
The minimum level for increased hardenability is 0.0008%, further additions having little additional effect, typical actual results are 0.002 – 0.003% boron in solution.
Additions of chromium (up to 0.70%), molybdenum (up to 0.5%), vanadium & niobium (trace only) are made to increase depth of hardening and improve temper resistance.
The effect on hardenability is greatest during rapid cooling when boron is retained in solution within the grain, locking the martensitic transformation.
Heat Treatment
The limited solubility of boron has a dramatic effect on transformation characteristics in heat treatment. Boron retards the formation of ferrite and pearlite, promoting the formation of martensite during rapid cooling and not depressing the martensite start (Ms) temperature.
When quenching boron steels, it is important that the cooling rate is high enough to produce a martensitic microstructure; developing higher strength and good toughness.
Slow cooling rates will lead to the presence of; upper and lower bainite, widmanstatten ferrite; developing lower strength and poor toughness.
Boron steels are either; fully heat treated by harden, quench and temper or; quenched and auto-tempered from hot working temperature.
Hot Working
Boron steels are less susceptible to grain growth due to the presence of titanium and have a wide hot working range. Typically; Hot working temperatures ~ 1050 C, Quenching temperatures ~ 900 C.
Machinability
In the as rolled / delivered condition boron steel grades are softer than equivalent engineering steel grades, avoiding the need for costly annealing prior to forming operations.
The addition of boron does not impair machinability, cutting, punching or drilling; suitable for both oxy-fuel profiling and cutting by sawing
Weldability
Boron steels, in spite of, good hardenability are readily weldable and can be welded in either the as rolled or heat treated condition. Suitable welding processes include but not limited to;
Manual metal arc with basic electrodes
All combinations of gas shielded metal arc
Auto-geneous TIG
Resistance spot welding
Laser conduction and/or laser penetration welding
Friction welding processes
The heat affected zone
The presence of titanium reduces the grain coarsened region and extends the grain refined zone.
If, the cooling rate in the grain coarsened region is high, there is a risk of the formation of coarse untempered martensite which is brittle and susceptible to hydrogen cracking.
When welding boron steels precautions should include but not limited to;
Low hydrogen practice
Calculation of pre-heat using the Pcm formula, suitable for micro-alloy and boron steel grades.
Aim to keep pre-heat and interpass temperatures below martensite finish (Mf) temperature.
Regulate and control heat input to maintain interpass temperature.
Avoid very high heat inputs; which may lead to heat sink and quenching effects in the heat affected zone.
Apply post heat below Mf temperature to reduce cooling rate and temper any coarse martensite which may form in the heat affected zone.
