What is the difference between EN 10025-6 S550Q high strength steel & SS400 ?

In terms of service, our service is a "one-stop" way of working. We have our own EN 10025-6 S550Q high strength steel processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as EN 10025-6 S550Q high strength steel cutting, welding, drilling, galvanizing, etc., at the lowest cost.

Hardness is the characteristic of providing excellent wear-resistant protection during the whole service life of wear resistant steel plate. High hardness minimizes wear because the sharp edges of the abrasive are difficult to cut into a hard surface. Wear resistant steel plate can be used for bucket, loader, dump truck, powder concentrator, chute and various wear-resistant lining plates. EN 10025-6 S550Q high strength steel, Wear resistant steel plate can withstand any form of wear from a variety of rocks, sand and gravel.

The wear-resistant layer of EN 10025-6 S550Q high strength steel wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy EN 10025-6 S550Q high strength steel carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

Molybdenum is a well known alloy element. Molybdenum can refine the grains of steel material, improve the hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperature. Adding molybdenum to EN 10025-6 S550Q high strength steel, structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
