Onsale AR450 Plates, AR450 Abrasion Resistant Steel Plates

Posted:9/21/2016 3:01:38 AM

AR450 plate, also known as wear resistant plate, is abrasion resistant (AR) quenched and tempered alloy steels. Abrasion resistant steels are not intended for structural applications. These steels should not be used for structural or main load-bearing members because of the possibility that brittle fracture may occur in these high hardness steels at the high stress levels encountered in such applications.

AR450 plate exhibits high abrasion resistance and hardness. The addition of carbon and manganese coupled with quenching and tempering increase the hardness of the steel and create a durable, impact-resistant surface. However, as hardness increases, formability and the ability to easily machine and weld the alloy decrease. Special machining processes are needed to prevent work hardening and chipping during manufacturing.
AR450 plate is onsale. Bebon will offer AR450 abrasion resistant steel plates with favorable price. AR450 plate is suitable for cutting and welding. Below is the detail of these machining.
Welding:
All the normal welding procedures can be used, provided that a professional welder pays special attention to the following factors:           
Use of correct working temperature.
Correct choice of welding consumables.
Suitable arc energy.
A reserved attitude to post-weld heat treatments should be taken because they have a tendency to weaken the most important property of these steels i.e. wear resistance.
Flame Cutting:
A heat affected zone will build up on a thermally cut surface which is similar to the heat affected zone on a fusion welded steel surface. The surface hardens to a depth of 1mm-2mm during flame cutting and post heat results in a soft tempered layer below this. When flame cutting, the pre-heating and working temperature instructions concerning welding can be used as a guideline.  In practice it is advisable to preheat when cutting plates, if the thickness is over 10mm.
The maximum allowable working temperature must be kept below 200°C in order that the wear resistance will meet requirements throughout the plate.  The cooling of a cut surface must not be accelerated under any circumstances, on the contrary, the cooling of the plate surface can be slowed down if necessary.  A plate brought in from cold outside storage must be allowed to warm up sufficiently before cutting.
