What is the difference between carbon steel Q235B and corten a steel angle

Our company was founded in 2000, which initially committed to providing high-quality steel corten a steel angle products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export corten a steel angle steel to the international market, opening up the international steel market.

Weather resistant steel sheet is a low-alloy high-strength steel that adds a small amount of alloying elements to ordinary steel to make it have good corrosion resistance in the atmosphere. This kind of material has a higher atmospheric corrosion resistance than ordinary carbon steel. corten a steel angle, Weather resistant steel sheet and plate is widely used in manufacturing industries such as containers, bridges, automobiles, railway vehicles, and construction abroad.

Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, corten a steel angle weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.

Stainless steel plate and other plates are like smelting, refining, casting, rolling, hot rolling and cold rolling is the final process steps in the manufacture of stainless steel. At present most of the world's corten a steel angle stainless steel factory use the AOD furnace furnace ldpe-g-nvp stainless steel production, its production accounted for about 70% of the world's stainless steel output, a VOD furnace a converter three-step method is used to produce stainless steel, its production accounted for about 20% of the world's corten a steel angle stainless steel production, production of stainless steel with other methods, its production accounted for about 10% of the world's production of stainless steel.

Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39. 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB. corten a steel angle, 45# steel chemical composition % (Carbon: 0.42 to 0.50, Silicon: ≤0.40, Manganese: 0.50 to 0.80, Sulfur: ≤0.045, Phosphorus: ≤0.045, Chromium: ≤0.40, Nickel: ≤0.40, Molybdenum: ≤0.10).

It is a modern high-tech professional enterprise integrating scientific research, corten a steel angle production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as corten a steel angle process technology development, technology transfer and related technical consulting and technical services.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
