Different types of stainless steel have different mechanical properties. Martensitic stainless steel has high strength and hardness, which is suitable for manufacturing parts with corrosion resistance, high strength and high wear resistance, such as turbine shaft, stainless steel cutter, stainless steel bearing, etc. ABS EH32 offshore oil drilling platform steel, Ferrite stainless steel has moderate mechanical properties and low strength. However, it is resistant to oxidation and is suitable for various industrial furnace parts.
Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business ABS EH32 offshore oil drilling platform steel department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and ABS EH32 offshore oil drilling platform steel after-sales service department constitute the service customer network.
S355J2 steel plate ABS EH32 offshore oil drilling platform steel rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the ABS EH32 offshore oil drilling platform steel single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
Oxygen (O) is a harmful element in steel such as ABS EH32 offshore oil drilling platform steel. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel ABS EH32 offshore oil drilling platform steel products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
