Wear Resistant Steel Plate refers to a special plate product designed for use under large-area wear conditions. At present, the commonly used wear-resistant plates are made of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity by surfacing welding with a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance. In addition, there are cast wear plates S690QL equivalent and alloy quenched wear plates.
The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, S690QL equivalent. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.
The S690QL equivalent steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the S690QL equivalent internal quality of the steel.
S690QL equivalent, 27SiMn material has high strength and wear resistance, high hardenability, medium plasticity during cold deformation, good machinability and fair weldability. It is mostly used after quenching and tempering, and can also be used in normalizing or hot rolling state. 27SiMn material chemical elements: C: 0.24-0.32, Si: 1.10-1.40, Mn: 1.10-1.40. 27SiMn material mechanical properties: tensile strength 980 MPa; yield strength: 835 MPa; elongation after fracture: 12%; impact energy: 39J. 27SiMn material can be used to make hot stamping parts with high toughness and high wear resistance, which do not need heat treatment or normalizing, such as tractor track pins.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
