Ar Plate Steel

Often called ar plate or abrasion resisting plate ar235 steel plate is an abrasion resistant as rolled carbon steel that contains a high carbon content.

Ar plate steel.

This plate product is intended for use in applications where a good balance of formability weldability toughness and abrasion resistance are required. This means that ar is harder due to the addition of carbon and formable and weather resistant due to added alloys. Hardox wear plate is the world s leading abrasion resistant ar steel. It is a high carbon steel alloy that provides greater impact and sliding abrasion resistance by comparison.

Abrasion resistant steel plate. Therefore ar plate is used in. Ar400 is a quench and tempered steel and may be difficult to weld due its high strength and hardenability. Abrasion resistant ar steel plate is a high carbon alloy steel plate.

Service temperature is 400 f. Welding ar plate to itself or any structure with dissimilar and softer or lower strength steel poses particular challenges the biggest of which is preventing cracking in the weld metal or heat affected zone haz of the ar plate. Ar 400 plate is a quenched and tempered high strength alloy steel which has superior abrasion resistance and toughness ar 400 alloy steel will reduce material handling costs to a minimum for earth moving mining and other similar industries in which a combination of toughness and abrasion resistance is required. What are you recommendations for welding ar400 plate.

Typical uses are wear plates truck bodies chute liners and storage bin liners. Abrasion resistant ar steel plate is a high carbon alloy steel designed specifically to have greater hardness properties than low carbon steel. Applications for ar400 include dump body liners hoppers crushers feeders cutting edges equipment buckets etc. Ar400 is thru hardened abrasion resistant alloy wear plate.

Hardox is hard through and through from the surface deep down to its core giving you extended service life and high productivity in the most challenging environments. Hardness range is 360 440 bhn with a nominal hardness of 400 bhn. The base steel around the weld rapidly heats and cools during welding resulting in a heat affected zone haz with high hardness. Carbon added during the formation of the steel plate substantially increases toughness and hardness but reduces strength.

Any hydrogen in the weld metal may diffuse into haz. However this increase in strength and abrasion resistance will make the steel less malleable. Much like ar450 and ar400 ar500 steel is a specific type of abrasion resistant steel. Ar 235 plate has been developed primarily to supply a low cost material for high abrasion applications.

Hardness typically comes at the expense of strength making ar wear resistant steel an ideal material for harsh high abrasion conditions and not for structural applications. This has a surface hardness of 477 534 bhn.
