Ar Plate Steel

Therefore ar plate is used in.

Ar plate steel.

Carbon added during the formation of the steel plate substantially increases toughness and hardness but reduces strength. 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. Any hydrogen in the weld metal may diffuse into haz.

Abrasion resistant ar steel plate is a high carbon alloy steel designed specifically to have greater hardness properties than low carbon steel. Service temperature is 400 f. What are you recommendations for welding ar400 plate. Much like ar450 and ar400 ar500 steel is a specific type of abrasion resistant steel.

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. 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. 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 235 plate has been developed primarily to supply a low cost material for high abrasion applications.

Abrasion resistant ar steel plate is a high carbon alloy steel plate. However this increase in strength and abrasion resistance will make the steel less malleable. Typical uses are wear plates truck bodies chute liners and storage bin liners. Ar400 is thru hardened abrasion resistant alloy wear plate.

This means that ar is harder due to the addition of carbon and formable and weather resistant due to added alloys. Ar400 abrasive resistance steel plate is intended for higher impact wear applications where cold bending and very good weldability is important. Abrasion resistant steel plate. 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.

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 plate product is intended for use in applications where a good balance of formability weldability toughness and abrasion resistance are required. It is a high carbon steel alloy that provides greater impact and sliding abrasion resistance by comparison.

Rapid cooling highly restrained joints and or excessive hydrogen in the weld metal or filler metals are among the. Applications for ar400 include dump body liners hoppers crushers feeders cutting edges equipment buckets etc.
