For the company's development and take-off, we work together to move forward and create a better tomorrow!

SM490B carbon steel material,We have marine steel CCS AH36 hot rolled plates 300tons in Shanghai stock. Specification: 12*1800*8000, 15*2100*8400, 15.5*3150*8200, 12.5*2380*7500, 21.5*2540*5200, 29*2160*6010, 17*1980*5720, 15.5*1700*8400, 18*2300*6750, 18.5*2680*8800, 14.5*1800*6500, 11*1890*6960, 17.5*1500*6790, 13.5*1900*6050, 14.5*1750*8300, 12*1830*9220, 13.5*1900*6050, 14*2000*6000, 13*2470*7780, 13*3020*6700, 12*1610*11240, 19*2090*7070, 14*1820*6500.

As the boiler steel plate 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.

SM490B carbon steel material,Q355GNHE corten steel is characterized by adding a small amount of Cu, P, Cr, Ni and other alloying elements to the steel, so that the steel material forms a dense layer between the rust layer and the substrate with a thickness of about 50 to 100 μm and good adhesion to the substrate metal. The amorphous spinel oxide layer prevents oxygen and water in the atmosphere from penetrating into the steel substrate, slows down the rust development to the steel material, and greatly improves the steel material's resistance to atmospheric corrosion.

SM490B carbon steel material,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. 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).

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
