Ar Plate Steel

Much like ar450 and ar400 ar500 steel is a specific type of abrasion resistant steel.

Ar plate steel.

Any hydrogen in the weld metal may diffuse into haz. Abrasion resistant ar steel plate is a high carbon alloy steel plate. Abrasion resistant steel plate. Hardness range is 360 440 bhn with a nominal hardness of 400 bhn.

Therefore ar plate is used in. Ar400 is thru hardened abrasion resistant alloy wear plate. This has a surface hardness of 477 534 bhn. Ar 235 plate has been developed primarily to supply a low cost material for high abrasion applications.

Typical uses are wear plates truck bodies chute liners and storage bin liners. Service temperature is 400 f. 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.

Hardox wear plate is the world s leading abrasion resistant ar steel. What are you recommendations for welding ar400 plate. Abrasion resistant ar steel plate is a high carbon alloy steel designed specifically to have greater hardness properties than low carbon steel. Metals depot stocks an wide range of thicknesses of ar 400 that can be purchased.

It is a high carbon steel alloy that provides greater impact and sliding abrasion resistance by comparison. This plate product is intended for use in applications where a good balance of formability weldability toughness and abrasion resistance are required. Carbon added during the formation of the steel plate substantially increases toughness and hardness but reduces strength. The base steel around the weld rapidly heats and cools during welding resulting in a heat affected zone haz with high hardness.

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. Ar400 abrasive resistance steel plate is intended for higher impact wear applications where cold bending and very good weldability is important. 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 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.

However this increase in strength and abrasion resistance will make the steel less malleable. Ar400 is a quench and tempered steel and may be difficult to weld due its high strength and hardenability.
