Wear-resistant steel plates, also known for abrasion-resistant steel plates, are specially designed and manufactured to resit harsh wear and impact conditions. These plates are made from high-quality steel alloys that have been hardened and treated to enhance their resistance against abrasion, erosion, and impact damage.
Properties of wear-resistant steel plates:
The critical characteristic of wear-resistant steel plates is their ability to withstand repeated friction, impact, and scratching, therefore reducing downtime and maintenance costs. They offer excellent resistance to abrasive materials, such as rocks, ores, coal, minerals, and grains, which can cause significant damage to unprotected surfaces. These plates also exhibit high hardness, toughness, and strength, enabling them to resist deformation and maintain their structural integrity under demanding operating conditions.
Application of wear-resistant steel plate:
Wear-resistant steel plates are commonly used in mining, construction, manufacturing, and material handling industries, where equipment and machinery are subjected to frequent wear, impact, and sliding abrasion. These plates provide a reliable and cost-effective solution to extend the lifespan and durability of critical components, such as buckets, chutes, crushers, hoppers, and conveyor systems.
Wear-resistant steel plates are available in various grades and thicknesses to cater to different application requirements. They can be easily fabricated and welded, allowing customized shapes and sizes to fit specific equipment or structures. Additionally, these plates can be further processed, such as bending, forming, cutting, or drilling, to suit different installation needs.
Overall, wear-resistant steel plates play a crucial role in protecting vulnerable components and structures from excessive wear and damage, thereby improving operational efficiency, reducing maintenance costs, and extending the service life of equipment in various industries.
Because of the different countries where the steel is produced and the different uses of the wear plates, the governments of various countries have established various production standards for wear-resistant steel plates. According to the actual situation of this website, we are back to listing some common production standards for the reference of incoming buyers.
China Standard:
GB/T 24186-2022: High strength abrasion resistant steel plate,sheet and strip for construction machine.
This standard applies to single-rolled steel plates with a thickness not greater than 120 mm and steel strips and sheared steel plates with a thickness not greater than 25.4 mm for wear-resistant structural components of mining, construction, and agricultural construction machinery.
GB/T 3274-2017: Hot-rolled plates, sheets, and strips of carbon structural steels and high strength low alloy structural steels.
This standard applies to hot-rolled steel sheets and strips of carbon structural and low-alloy structural steels with a thickness not greater than 400mm.
American standard:
ASTM A514/A514M-13: Standard specification for high-strength wear-resistant alloy steel plates
ASTM A745/A745M-14(2020): Standard Specification for Wear-Resistant Carbon Steel Castings
British Standards:
BS 4844-2:2007+A2:2017: Standard specification for wear-resistant alloy cast iron
BS EN ISO 6506-1:2014: International standard for methods of testing the hardness of metallic materials
BS EN ISO 6508-1:2016: International standard for methods of testing Brinell hardness in metallic materials
BS EN ISO 148-1:2016: International standard for the preparation of impact specimens for impact testing of metallic materials
Japanese Standards:
JIS G4051: Standard specification for hot-rolled steel plates and strips for mechanical structures of carbon steel
JIS G3131: Standard Specification for Hot-Rolled Low Carbon Steel Plates and Strips
JIS G3141: Standard Specification for Cold-Rolled Low Carbon Steel Plates and Strips
The hardness of abrasion resistant steel is determined by a Brinell hardness test. This test uses a small steel ball to inflict force on a material. The indentation created by the steel ball is then measured and used to calculate Brinell hardness number (BHN).
China:
According to GB/T 24186-2022, the grade of Chinese wear-resistant steel plate consists of two parts: the hanyu pinyin initials "NM" for "wear-resistant" in Chinese and the Brinell hardness value of the specified surface. The common grades include NM300, NM360, NM400, NM450, NM500, NM550, NM600.
According to GB/T 24186-2022, the size, weight, and allowable deviation of wear-resistant steel plates are stipulated by GB/T 709-2019.
GB/T 709-2019:
Thickness: 3mm-100mm
Width: 1000mm-4600mm
Length: 2000mm-16000mm
Weight: weight calculation formula: weight (kg) = thickness (mm) × width (mm) × length (mm) × 0.00785
Allowable deviation: The value range of allowable deviation needs to be calculated according to the actual product length, width, and height values.
International Standards:
Common international grades of wear resistant steel plates include AR200, AR235, AR400, AR450, AR500, and AR600.
