AR 500 plate in non-traditional use 1

[Saari]

I am currently in a situation where people want to use 500 BHN liner plate in a loaded application (ie, chutes). They will be under load.

I am looking for viable for & against arguments

If you look for wear and abrasion resistance, with or without impact loading, hardness alone may not be the most useful parameter. The application should be defined more precisely and a suitable solution looked for.

The abrasion resistant wear plate can be used under "load" conditions provided you design for this material. Fabrication and welding must be performed under controlled conditions, not like dealing with A 36 structural steel.

Typically, AR 500 plate is furnished in a quenched and tempered heat treatment condition for use under impact loading and abrasive wear service conditions.

Caution should be used for fabrication (bending and welding). Normally, a lower strength filler metal like E7018 H4 weld rod is used for welding this plate under controlled preheat and interpass conditions.

Frankly, I would still use the AR 500 plate as liner material instead of building chutes and running the risk of having to replace section of the chutes for repairs instead of simply changing out liners.

This stuff is a joy to work with. Hope you have a good plasma torch for cutting and air forming dies for your brake.

It may be hard to obtain right now as the supply is tight due to armor plate use for our adventure in Iraq.
