09CuPCrNi-B steel as rolled, killed

Weathering steel plate refers to the low alloy structural steel with protective rust layer and atmospheric corrosion resistance, which can be used to manufacture steel structures such as vehicles, bridges, towers, containers, etc. Compared with 09CUPCRNI-B steel, ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only a small amount of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and so on. The total amount of alloy elements only accounts for a few percent, instead of more than 10 percent as stainless steel, so the weathering steel price is relatively low.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with 09CUPCRNI-B steel ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

Booking space and making power of attorney (ten copies of order); the data of the original order shall be correct and consistent to the greatest extent when making the order, so as to reduce the frequent changes in the subsequent process. For booking with the company's seal for booking space, if the accessories for booking space (such as the price confirmation document of the shipping company) need to be provided, they can only be booked with all of them. Obtain the shipping space allocation receipt and extract the ship name, voyage number and B / L number information.

09CUPCRNI-B 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 09CUPCRNI-B 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. 09CUPCRNI-B steel annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
