S890QL equivalent steel price forecast

The full name of 304 stainless steel pipe is SUS304 stainless steel pipe. SUS304 stainless steel pipe belongs to the stainless steel pipe made of American trademark. It is equivalent to Chinese grade 0Cr19Ni9 stainless steel pipe, which is generally replaced by 0Cr18Ni9. The mechanism of stainless steel rust prevention is that the alloy elements form a fine oxide film, which insulates the touch of oxygen and prevents continued oxidation.

As the boiler steel plate S890QL equivalent steel is working under medium temperature (below 350 ℃) and high pressure, the boiler steel plate is not only subjected to high pressure, but also subjected to impact, fatigue load and water and gas corrosion. The performance requirements for boiler steel mainly include good welding and cold bending performance, certain high temperature strength, alkali corrosion resistance, oxidation resistance, etc.

S890QL equivalent steel annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of S890QL equivalent steel annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. S890QL equivalent steel annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about S890QL equivalent steel pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.
