Rwm/homemade landslides

Good evening sorry if this has been covered before but I was wondering if there was a source to buy rwm landslides from. Or if I was to make my own what would be the best material to use. Many thanks dan

I use digger bucket edge available in various thicknesses and widths. Is hard wearing and can be cut and drilled. It comes with a tapered edge but I turn this to the top with the taper facing the back of the mouldboard.

Easy
I have made mine using lemkin reversible landsiides cut ends square to length then weld together

Slow drill and counter sink holes job done

How many landslides will you wear out in a weekend? (wear not ware). The landslide resists the mouldboard thrust but is never high enough. A piece of laminate floor would endure one plot.

Plough parts are hot forged ,,its highly unlikely you could make any wareing part to the correct shape and sizes,,its specialized material

Might well have been that way 30 years ago. Not any more though. Get yersen into the digital age!
Hardox is ok but does not behave all that well if you are going to weld it. Lots of good wear plate about now around about 460 hardness which just by way of chance is the same as original TCN shares were.

For some reason the hardox I used welded very well with both stick and mig at the end of the day it was used in quarries as a wear face to make things last longer in a very abrasive environment I gather it is even used now to make bulk tipper bodies that are used in a similar environment

Not trying to be a smart arse but this explains things in more detail. AR or abrasion resistant is through hardened where as case hardened is only surface hardened. Kristeel exhibits similar properties to surface hardened.
Hardox is amongst the hardest. I use quite a bit of 400, 450 and 460 as these are slightly easier to countersink, machine and weld well
AR400 vs. AR450 vs. AR500 – Understanding Abrasion Resistant Steel
Abrasion Resistant Steel Plate

In construction and fabrication, the grade and composition of the steel plate materials used make a huge impact on the final product. Abrasion resistant steel plate is a common steel plate that boasts a harder, tougher quality that lasts about four times longer than ordinary high-strength structural steel plate.
But what makes it tougher, and how do you know when your project requires abrasion resistant steel?
We get this question a lot, so here is the run-down on abrasion resistant steel plate, as well as the differences between hardness levels AR400, AR450, AR500 and beyond.
What is Abrasion Resistant Steel Plate?
Abrasion resistant (AR) steel plate is a high-carbon alloy steel plate. This means that AR is harder due to the addition of carbon, and formable and weather resistant due to added alloys.
Carbon added during the formation of the steel plate substantially increases toughness and hardness, but reduces strength. Therefore, AR plate is used in situations where abrasions and wear and tear are the main causes of failure. AR plate is not ideal for structural construction uses like support beams in bridges or buildings.
Common uses for AR plate include conveyors, buckets, dump liners, construction attachments, grates, body armor and ballistic plates (and as targets at shooting ranges).
How the Quenched & Tempered Process Creates AR Plate
AR material is produced by quenching and tempering forged steel blocks, or ingots. During this process, the grain structure is changed to increase toughness and encourage formability (or, to be less brittle), and results in through-hardening of the material.
Quenching and tempering (Q&T) is a two-part process:
Quenching occurs when steel brought to a high temperature – usually between 1,500-1,650-degrees Fahrenheit – is rapidly cooled with water. This process causes crystal structures to form within the steel, increasing hardness.
Tempering is the process of re-heating quenched steel to a below-critical temperature (around 300-700-degrees Fahrenheit), and then allowing the plate to cool in normal air temperatures.
Reheating the material breaks down the crystal structures formed during the quenching process, while the long cooling allows the crystal structures to refrom – maintaining most of the strength and hardness, but adding to overall ductility.
What’s With the F?
Many times, abrasion resistant steel is labeled "AR400F" and "AR450F" (and sometimes "AR500F"). Today, AR material with or without the "F" are interchangeable, but – historically – material with an "F" simply meant that it was "formable" and could be bent to a certain degree without cracking.
When mills produced both formable and non-formable steel plate, formable was slightly more expensive. However, diminished demand and more competitive pricing has resulted in the production of formable-only AR steel.
Tempering Steel Plate

What is Through-Hardening?
AR steel is often described as being through-hardened, but what does that really mean?
When grain structure changes during the initial heating stage of Q&T, the composition of the entire plate changes. This is referred to as through-hardening. Through-hardening differs from "case-hardening," also referred to as "surface-hardening," which only hardens the surface while allowing the metal deeper underneath to remain soft. In this case, the composition, or hardening, of the plate only changes at the surface level.
AR400 versus AR450 versus AR500+
Before we dive into the difference between these common types of AR steel, it is important to clarify that AR steels are not governed by a specific chemistry, but a level of hardness.
Different mills may have different “recipes” for AR steel, but produced material is administered a hardness test – known as the Brinell Test – to determine the category in which it falls.
The technical difference between AR400, AR450 and AR500 is the Brinell Hardness Number (BHN), which indicates the material’s level of hardness:
AR400: 360-440 BHN Typically
AR450: 430-480 BHN Typically
AR500: 460-544 BHN Typically
AR600: 570-625 BHN Typically (less common, but available)
So, what does this mean in terms of usability? How do you know which level of hardness your project needs?
Projects that require AR materials are typically those that need a specific balance between hardness and brittleness. As you increase hardness, you also increase brittleness, making the material difficult to form, shape and weld. For some projects, hardness is critical, so brittleness is sacrificed. But in other cases, the material must be formed and handled, so the level of hardness must be reduced.
As a general rule, AR400 and AR450 are the “sweet spots” in terms of good hardness combined with good formability. For projects that truly beat up the material, AR500 and AR600 will last longer and need to be replaced less frequently.
Ultimately, you and your team will be the best judge of which material your project needs. Cost, of course, comes into play, as sometimes it’s worth having a formable material that needs to be replaced more often.
