How to distinguish the normal floating rust and rusting of hsla steel grades

The company always adheres to the hsla steel grades principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great hsla steel grades cause. Customers are welcome to visit our company at any time. We are always ready to support you.

The bridge steel plate hsla steel grades produced by BBN company has pure steel, flat and smooth plate surface, small difference between plates, -40 ℃ impact value and aging impact value are stable, and the margin is large. Bridge steel plates can be controlled by rolling, cooling, normalizing, and tempering organize production with different production processes. This bridge steel hsla steel grades is widely used in the manufacture of large railway bridges and highway bridges.

In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel hsla steel grades surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.

Temperature has a great influence on the strength of the material, hsla steel grades. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

Chemical composition of 65Mn steel: C 0.62-0.70, Si 0.17-0.37, Mn 0.90-1.20, Cr ≤ 0.25, Ni ≤ 0.30, Cu ≤ 0.25. 65Mn steel mechanical properties: tensile strength: ≥735 Mpa, yield strength: ≥430 Mpa, elongation after fracture: ≥9%, reduction of area: 30%, impact absorbed energy: no impact. hsla steel grades, 65Mn steel has high strength, high hardenability, less decarburization tendency, overheat sensitivity, easy to produce quenching cracks and temper brittleness. 65Mn steel is used for making various flat and round springs, leaf springs, spring rings, valve springs, steel wire cold coil springs, clutch springs of light trucks and cars.

Our company is one of the famous steel suppliers in China, specializing in the production of steel plates, steel pipes and other steel products. If you are interested in steel products, or need to purchase a large number of hsla steel grades steel plates and pipes. Please contact our company directly, we will provide the most favorable price and the most perfect system, our employees have professional product knowledge. We hope to provide you with high quality products.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
