Factory Spot Plate Nm360 Nm400 Nm450 Nm500 Nm550 Mn13 Hot Rolled Wear Resistant Steel Plate

The wear-resistant steel plate is composed of low-carbon steel plate and alloy wear-resistant layer, and the alloy wear-resistant layer is generally 1/3~1/2 of the total thickness. During operation, the matrix provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resisting layer provides wear-resisting properties that meet the requirements of specified working conditions. There is metallurgical bonding between the wear-resisting layer of wear-resisting steel plate alloy and the substrate. Through special equipment and automatic welding process, the high hardness self protective alloy welding wire is uniformly welded on the base plate. The composite layers are one to two or even multiple layers. During the composite process, uniform transverse cracks occur due to different alloy shrinkage ratios, which is a remarkable feature of the wear-resistant steel plate. The alloy wear-resistant layer is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are also added. The carbides in the metallographic structure are distributed in fibrous form, and the fiber direction is perpendicular to the surface. The micro hardness of carbide can reach above hv1700-2000, and the surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperature, maintain high hardness, and have good oxidation resistance. They can be used normally under 500 ºC. The wear-resistant layer has narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (s, w), etc; It mainly consists of chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel and boron are also added. The carbides in the metallographic structure are distributed in fibrous form, and the fiber direction is perpendicular to the surface. The carbide content is 40-60%, the microhardness can reach above hv1700, and the surface hardness can reach HRC58-62. Wear resistant steel plates are mainly divided into general-purpose type, impact resistant type and high-temperature resistant type; The total thickness of wear-resistant steel plate can reach 3mm at least and 80mm at most; Wear resistant steel plate can be rolled into wear-resistant pipe with minimum diameter of DN200, and can be processed into wear-resistant elbow, wear-resistant tee and wear-resistant reducer.

Wear resistant steel plate has high wear resistance and good impact performance. It can be cut, bent and welded. It can be connected with other structures by welding, plug welding and bolt connection. It is time-saving and convenient in the process of maintenance. It is widely used in metallurgy, coal, cement, electricity, glass, mining, building materials, brick and tile and other industries. Compared with other materials, it has high cost performance, It has been favored by more and more industries and manufacturers. 

1. It have certain anti-rust ability.
2. The thickness is precise, and usually tolerance is within -0.1/+0.1mm.
3. It has high wear resistance and good impact performance. It can be cut, bent and welded. It can be connected with other structures by welding, plug welding and bolt connection.
4.The wear resistant alloy steel layer is even, so that the hardness on surface of plate is qualified and closed to each other.
5.Relatively low cost.
6.It is widely used in metallurgy, coal, cement, electricity, glass, mining, building materials, brick and tile and other industries.
 

We have more than 10,000tons wear steel plate stocks all the year time. The grades can meet most of the demands, and the thickness differ from 3mm to 80mm. So short time delivery is possible.
                                     

*What is your paying terms?
Our usual paying terms are 30%TT as deposit and balance paid after seeing copy of bill of loading. For clients cooperated for more than one year, we accept 20% prepay. Beside we do business also under D/P and LC terms.

*How long is your delivery time?
For the goods we have in stocks, we deliver the goods within 5days. If it is a production order with volume not above 200tons, the delivery time will usually be within 20days after sealing contract. And the delivery time shall be slightly longer for order volume above 200tons.

*Can you do partial shipment?
We will follow client request to do partial shipment or not. Partial shipment is not a problem for us.

*What is your Minimum Order Quantity?
For goods in stocks we supply starting with one piece. Shall it is a production order, the MOQ is 3tons. Please be noted price based on MOQ will be slight higher than FCL condition due to higher unit cost.

*Before cooperation we want a sample for inspecting of quality, is that okay?
  We can provide a free sample for you shall sample value not above 30USD, you only need to pay the express charge. For a sample valued more than 30USD, the express charge and just one half of sample value is on the account of you, and we afford the other half.

*What is the mode of transportation?
Ocean freight is the most important shipping way, and we choose the ship line based on soonest and earliest shipping time, rather than cheaper cost; or we follow clients '  instruction if there is one. Also railways will be chosen by us when it is more convenient. For samples and papers, the transportation will be by air.
