Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and hardness of Q295NH heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported hardness of Q295NH to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
The yield strength of A36, D36, E36 and F36 is not less than 355N/mm^2, and the hardness of Q295NH tensile strength is 490~620N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20 ° respectively. Impact toughness that can be achieved at -40℃, -60 ℃.
Weathering steel plate hardness of Q295NH for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate hardness of Q295NH has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.
In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and hardness of Q295NH pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30. Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J. Due to the effect of carbon and chromium content, hardness of Q295NH, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after quenching and tempering, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.
We are professional hardness of Q295NH carbon steel plates supplier with good reputation, and have participated many significant projects that finished with carbon steel materials in the world. If you have any question about carbon steel materials, such as A36 steel modulus of elasticity, A283 grade C properties, A572 grade 50 hardness, hardness of Q295NH EN 10025 S235JR equivalent Indian standard, S355JR specification, carbon steel price etc., please feel free to consult us.
After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
