Ar Plate Steel

The base steel around the weld rapidly heats and cools during welding resulting in a heat affected zone haz with high hardness.

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. Abrasion resistant ar steel plate is a high carbon alloy steel designed specifically to have greater hardness properties than low carbon steel. Ar 235 plate has been developed primarily to supply a low cost material for high abrasion applications. Metals depot stocks an wide range of thicknesses of ar 400 that can be purchased.

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. Abrasion resistant ar steel plate is a high carbon alloy steel plate. Abrasion resistant steel plate. Applications for ar400 include dump body liners hoppers crushers feeders cutting edges equipment buckets etc.

Rapid cooling highly restrained joints and or excessive hydrogen in the weld metal or filler metals are among the. 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. Carbon added during the formation of the steel plate substantially increases toughness and hardness but reduces strength. Typical uses are wear plates truck bodies chute liners and storage bin liners.

Hardness range is 360 440 bhn with a nominal hardness of 400 bhn. Ar400 is thru hardened abrasion resistant alloy wear plate. It is a high carbon steel alloy that provides greater impact and sliding abrasion resistance by comparison. Ar400 abrasive resistance steel plate is intended for higher impact wear applications where cold bending and very good weldability is important.

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. 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. Ar400 is a quench and tempered steel and may be difficult to weld due its high strength and hardenability.

This has a surface hardness of 477 534 bhn. Much like ar450 and ar400 ar500 steel is a specific type of abrasion resistant steel. 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. Therefore ar plate is used in.

Any hydrogen in the weld metal may diffuse into haz. What are you recommendations for welding ar400 plate.
