Weathering steel is mainly used in railway, vehicles, bridges, towers and other steel structures exposed to the atmosphere for a long time. shipbuilding RD 36 hull steel plate. Weathering steel is used to make structural parts such as containers, railway vehicles, oil derricks, seaport construction, oil production platform and containers containing hydrogen sulfide corrosion medium in chemical petroleum equipment. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, which benefits the weathering steel component manufacturers and users.
Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate shipbuilding RD 36 hull steel plate has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts
With the increase of temperature, the yield limit of shipbuilding RD 36 hull steel plate will decrease monotonically, but the tensile strength of shipbuilding RD 36 hull steel plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of shipbuilding RD 36 hull steel plate. Near the blue brittleness temperature, the shipbuilding RD 36 hull steel plate strength increases and the plasticity decreases. The elongation and section shrinkage of shipbuilding RD 36 hull steel plate increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. shipbuilding RD 36 hull steel plate, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.
We are engaged in shipbuilding RD 36 hull steel plate corten steel, weathering steel, atmosphere corrosion resistant steel materials. After receiving your inquiry about the weathering steel, we will make quotation for you at the first time. Meanwhile, our professional team can give you valuable answers about all kinds of question about the weathering steel. For example, corten steel cost per square foot, S355J2WP equivalent, shipbuilding RD 36 hull steel plate ASTM A242 steel properties, A588 steel yield strength, etc. If you have any demands or questions about weathering steel, please feel free to contact us.
Our company will accept the product quality objection registration record, pass it to the shipbuilding RD 36 hull steel plate production unit and relevant departments, and timely coordinate the supervision of product shipbuilding RD 36 hull steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
