hot rolled 09CuPCrNi-B steel angles size measurement

hot rolled 09CUPCRNI-B product is a low-alloy high-strength steel that adds a small amount of alloying elements to general steel to make it have corrosion resistance in the atmosphere. Weathering steel has 2-8 times the atmospheric corrosion resistance of ordinary carbon steel, and the longer the service time, the better the corrosion resistance. In addition to excellent weather resistance, weathering steel also has excellent mechanical and welding functions.

The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of hot rolled 09CUPCRNI-B structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of hot rolled 09CUPCRNI-B etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in hot rolled 09CUPCRNI-B etc. steel is strictly controlled.

Turkey produced 8.97 million metric tons of crude steel in the first quarter, with a 9.6 percent increase from the same month of last year. Iran's crude hot rolled 09CUPCRNI-B steel production in March amounted to 6.75 million mt. up by 13.2 percent year on year. The CIS registered a hot rolled 09CUPCRNI-B crude steel output of 25.15 million mt. falling by 0.6 on year-on-year basis, with Russia producing 17.9 million mt, down by one percent, and Ukraine producing 5.32 million mt, falling by 3.4 percent, both on year-on-year basis.
