SA387Gr5Cl2 steel material is suitable for refining and gas treatment in hydrogenation and conversion equipment at high temperature. The maximum thickness of Hardox 450 machining, SA387Gr5Cl2 steel plate can reach 250mm. According to different thickness and impact requirements, the heat treatment of SA387Gr5Cl2 steel plate is normalizing plus tempering or normalizing plus rapid cooling plus tempering. By using special smelting method, the content of phosphorus is reduced so that sa387 has high brittleness resistance and good impact toughness at low temperature.
The chemical composition difference between Hardox 450 machining, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between Hardox 450 machining, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
The boiler steel pipe has excellent anti-oxidation and corrosion performance: the general steel pipe is easy to be corroded under high temperature and produces harmful substances, but the boiler steel pipe has no such worries. The high-precision material and wall thickness of the boiler steel pipe can effectively prevent the corrosion. Good tensile strength of Hardox 450 machining, boiler steel pipe: it can keep the original state well without affecting its quality after being heated and stretched.
