8MM SIZE IN 2000*6000MM PLATE SHEET HARDOX FOR Boiler Plate
Hardox® 450 can be welded with all conventional arc welding methods for ordinary and high-strength steel. Use welding consumables with a yield strength of max.
500 MPa and a sufficiently low hydrogen content of max.
5ml/100 g of weld metal.The following consumables fulfill the hydrogen criteria: • All solid wires applied at MAG (GMAW) and TIG welding • MAG welding with flux cored wires (FCAW): Rutile and basic types • MAG welding with metal cored wires (MCAW): Certain types • SAW: Basic types of fluxes in combination with solid wires Welding materials with these properties reduce residual stress levels in the joint and its sensitivity to cold cracking. Preheating can be avoided by welding with austenitic stainless consumables according to type AWS 307 or AWS 309.
The wear-resistant steel plate is composed of a low-carbon steel plate and an alloy wear-resistant layer. The alloy wear-resistant layer is generally 1/3 to 1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity against external forces, and the alloy wear layer provides wear resistance that meets the requirements of specified working conditions.
There is a metallurgical bond between the wear-resistant steel plate alloy wear-resistant layer and the substrate. Through special equipment and automatic welding process, the high hardness self-shielding alloy welding wire is uniformly welded on the substrate. The composite layer has one to two layers or even multiple layers. During the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear. It is a remarkable feature of wear-resistant steel plate.
The alloy wear-resistant layer is mainly made 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 shape, and the fiber direction is perpendicular to the surface. The microhardness of carbide can reach above HV1700-2000, and the surface hardness can reach HRC58-62. Alloy carbide has strong stability at high temperature, maintains high hardness, and also has good oxidation resistance. It can be used normally within 500°C.
Wear-resistant layer manifestations include narrow channels (2.5-3.5mm), wide channels (8-12mm), curves (S, W), etc.; mainly chromium alloys are used, and manganese, molybdenum, niobium, nickel, and boron are also added And other alloy components, the carbides in the metallographic structure are distributed in the form of fibers, 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 three categories: general-purpose, impact-resistant and high-temperature resistant types; the total thickness of wear-resistant steel plates can reach 5.5 (2.5+3) mm as small as possible, and the thickness can reach 30 (15+15) mm; Rolling small-diameter DN200 wear-resistant pipes can be processed into wear-resistant elbows, wear-resistant tee, and wear-resistant reducer.
Our company can produce low alloy high strength abrasion resistant steels of grade NM360, NM400, NM450, NM500, NM550 and NM600 which have high strength and good abrasion resistant properties, good toughness and weldability, excellent processing properties and formability. Good performances of our company’s plates have been positively proven in different climates, terrains and environments.
These grades of plates are mainly applied for excavators, front wheel loaders, tippers bodies, conveyers, chutes, containers,
crushers, fragmentizes, mixers, sieves, demolition tools and barges. Our company’s abrasion resistant plates maximize the abrasion
resistant performance of products, reduce the risk of accidental shutdown and contribute to making precise equipment maintenance plan as per different situations and the service of life is doubled,tripled or even five times multiplied.in the mean time,the plates can make the final products and machines get lighter weight themselves,longer life and reduce emission of co2,because of the combination of material’s high hardness, good toughness and high strength.
