Effect of Boron on properties of hardox 500 plate application

Based on the main HARDOX 500 plate application business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and 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 HARDOX 500 plate application products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Both 20# seamless steel pipe and 20G seamless steel pipe are carbon structural steel with average carbon content of 0.20%. There are big differences in the use standard, chemical composition, mechanical properties and price between HARDOX 500 plate application, 20# seamless steel pipe and 20G seamless steel pipe, so they must be selected correctly in the design and use, so as to avoid affecting the service life or even causing destructive accidents. The purpose of HARDOX 500 plate application, GB8162 20# seamless steel pipe is for general structure, the purpose of GB8163 20# seamless steel pipe is for conveying fluid, and the purpose of GB3087 standard 20# seamless steel pipe is for low and medium pressure boiler. 20G seamless steel pipe is used for high pressure steam boiler and pipeline.

Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance. Our shipbuilding steel plate and HARDOX 500 plate application steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas.

As the tungsten content increases, the strength and toughness of the NM360 wear-resistant steel plate increase. When the mass fraction of tungsten exceeds 1.06%, the toughness decreases due to the increase in the amount of carbide precipitation. This is because tungsten combines with carbon atoms in the NM360 wear-resistant plate to form a short-range ordered C-w atom pair bond structure. The C-w atomic bond is stronger than the C-Mn and C-Fe atomic bonds. Therefore, after adding tungsten to the NM360 wear-resistant steel plate, cracks will be formed, and the energy required to break the atomic bond will be greatly increased. The toughness and strength of HARDOX 500 plate application, NM360 wear-resistant steel plate treated with water toughening treatment will also be significantly improved.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. HARDOX 500 plate application, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785
