The rockwell hardness of S460QL1 steel grade

We will return our customers with zealous service attitude, high quality products and favorable price. We have been accumulating, perfecting, developing and expanding constantly. We have huge S460QL1 steel grade steel products stock. We have won the trust and support of our customers with high-quality service and excellent product quality. The company adheres to the development concept of honesty and win-win cooperation. We are willing to form an alliance with like-minded partners to work together for development and common progress.

As a bulk commodity, the rise and fall of S460QL1 steel grade, steel pipe prices are related to many downstream industries, such as construction industry, railway, highway, urban public transport and other infrastructure construction, industry and real estate. The price of S460QL1 steel grade, steel pipe rises and falls every day, and is guided by the quotation market in various places. However, in fact, the procurement of steel pipes is more complicated than this, and the market guide price can only be used as a reference.

Tempering the important S460QL1 steel grade welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve S460QL1 steel grade strength, plasticity and toughness.

Common carbon killed steel plates are steel plates made by hot-rolling ordinary carbon structural steel killed billets. The advantage of S460QL1 steel grade, killed steel is that the chemical composition is uniform, so the mechanical properties of each part are also uniform, the welding performance and plasticity are good, and the corrosion resistance is strong.
Common killed steel plates are mainly used to produce components that withstand impact at low temperatures, welded structures and other structural parts that require higher strength.
