Abrasion Resistant Steel AR400 Plate

AR400 abrasion-resistant steel plate is a quenched-and-tempered, wear-resistant flat steel designed for applications that require extended service life in high-wear environments. With a nominal Brinell hardness around 400 HBW, AR400 combines high hardness and excellent abrasion resistance with practical fabrication properties.

Key features:

• High wear resistance and extended service life (commonly up to several times longer than standard structural steels)
• Nominal hardness: ~400 HBW (Brinell)
• Good cold-formability and toughness for many fabrication tasks
• Excellent weldability with low tendency to cold-crack when proper procedures are followed
• Good resistance to impact and abrasive wear in demanding conditions
• Supplied typically in as-rolled / quenched-and-tempered condition

Commercial details:

• Supplied for industrial and heavy-duty applications where abrasion resistance is critical
• Available in a range of plate thicknesses (starting from 3 mm; additional thicknesses, widths, lengths, and machining/cutting services available on request)
• Manufactured and sold under various brand designations — hardness is commonly used to identify the grade (e.g., "AR400").

Ordering guidance:

Provide required thickness, length, width, quantity, and any cutting, edge preparation or heat-treatment requirements when requesting a quotation. Specify intended use or welding/fabrication needs so the supplier can recommend appropriate supply condition and processing instructions.
