What grade is Q295NH steel welding?

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional Q295NH steel welding production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of Q295NH steel welding leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

The company produces and export steel plates and steel section products of various materials all year round. The width of the Q295NH steel welding thin plate is 500 - 1500 mm; the width of the thick plate is 600 - 3000 mm. Steel plates are classified by steel type, including ordinary steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, etc .; according to use, there are shipbuilding plate, pressure vessel plate, wear resistant steel plate, bridge builidng steel, corten steel plate, and pipeline steel plate.

Application of Q295NH steel welding stainless steel coil: 1. Automobile industry. As a structural material of automobile, stainless steel coil can not only greatly reduce the weight of vehicle, but also greatly improve the service life of automobile. 2. Water storage and transportation industry. The storage and transportation equipment based on stainless steel coil is recognized as the most sanitary, safest and most efficient water industry equipment. 3. The construction industry. The decorative panels of exterior walls and interior walls are generally made of stainless steel, which is not only durable, but also very beautiful.

After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of Q295NH steel welding, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.

Q295NH steel welding, Chinese material Q235B is one of the most widely used carbon steel in the world. Some like to compare its strength with other equivalent steel grades. We need to take care that the Q235B steel strength varies with thickness. For the min. yield strength of Q235B steel plate: it is 235Mpa if thickness ≤16mm, 225 Mpa for thickness 16-40mm, 215 Mpa for thickness 40-60mm, 205 Mpa for thickness 60-100mm, 195 Mpa for thickness 100-150mm, 185 Mpa for thickness over 150mm. The tensile strength of Q235B steel plate is 375-500 Mpa.

we are the best professional steel manufacturer in China. We can supply kinds of steel product size，if you want to purchase steel plate or steel pipe and other products. Please contact us freely. we can give you the Q295NH steel welding best price with high quality.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
